THE EASY TO USE CAVITYCOMFORT PUMP FOR FRESHLY MASHED ORGANIC SUSPENSIONS

 

The CC series was developed for harsh applications in which long downtimes for service and maintenance work are not acceptable - such as pumping freshly mashed organic suspensions, i.e. highly viscous media loaded with large quantities of fibrous solid matter.To get more news about magnetic drive pumps accessories, you can visit brysonpump.com official website.

The QuickService design is one-of-a-kind. Vogelsang has managed to decisively improve the tried-and-tested concept of the progressive cavity pump: Compared to conventional progressive cavity pumps, service and maintenance work is significantly quicker and takes up less space, because the innovative QuickService design means there is no need to disassemble parts of the pipe. All essential parts, including the gasket, can be quickly and easily changed, so the pump is soon operational again. Even the mechanical seal in the trusted Quality Cartridge design is easy to replace in the CC series.

At the same time, attention was paid to creating a sturdy and fault-resistant design; features that are essential for biogas plants: The large free passage is ensured over the entire length, preventing clogging and blockages caused by coarse disruptive matter such as foil residue and wood. The sturdy design of the drive line, including the cardan shaft, makes the progressive cavity pumps in the CC series ideal for high dry matter content and media loaded with foreign matter. This means that the unique overall concept of the CC series ensures long service lives, short downtimes for service and maintenance, and low operating costs for your biogas plants.
If a gap arises between rotor and stator due to wear in operation, the capacity drops. Whereas with conventional progressing cavity pumps, this often means a sudden drastic fall of the pump performance and the replacement of the rotor and stator, the HiCone solves this with axial readjustment of the rotor. The conical shape ensures the gap is regulated, as a result of which the pump is back to its original condition and the pumping capacity returns to 100 percent. Instead of the costly and time-consuming changing of parts, there is a quick and easy adjustment - during ongoing operation.

Combined with Vogelsang's integrated QuickService concept, this means significantly reduced life-cycle costs for the user and higher pump availability, since there are no elaborate service deployments. If replacement is nevertheless necessary, the rotor-stator unit is swung out and can then be renewed either as a unit or individually. A wear-resistant sleeve, which does not need to be unmounted to change parts, protects the sturdy cardan shaft.
Thanks to the clever adjustment system, rotor and stator can be optimally positioned to each other according to operating parameters like pressure, temperature and viscosity. This results in lower power consumption, which reduces the electricity requirement. Wear is also reduced at the same time.

In addition, the HiCone's automatic start-up saves power. The positioning of the rotor and stator in relation to each other is in such a way, that there is only minimal clamping between them. This means that a smaller motor is needed to ramp up the pump than in conventional progressive cavity pumps, which reduces the power requirement when starting the pump to a minimum. This increases the energy efficiency and reduces the costs for power electronics. The result is lower electricity costs and reduced procurement expense for users. The start-up process is fully automatic without the need for additional control. The clamping between the rotor and stator can be adjusted during the entire service life at the touch of a button or at the click of a mouse from the control room.

Continuous and precise metering and mixing of adhesives

 

When processing adhesives and sealants, as well as epoxy resin and silicone, continuous metering is necessary for certain applications. Metering systems with progressive cavity pumps are suitable for this. These work based on the volumetric metering principle, meaning that they enable highly precise metering of the material quantity. DOPAG offers two metering systems with progressive cavity pumps:To get more news about progressive cavity pump, you can visit brysonpump.com official website.

Progressive cavity pumps work with no pulsation. Consisting of two components, the stator-rotor combination is the heart of the progressive cavity pump. This is a volumetric metering system that is sealed leak-free. It conveys the material continuously without any restrictions on volume, with low shear and gently in an axial direction. Progressive cavity pumps are therefore highly suitable for processing filled and abrasive materials. Rotordis and rotormix are each available in four different nominal sizes: 0.01, 0.05, 0.15 and 0.30 ml/U. Rotordis enables shot sizes from 0.002 ml (2 μl) to be processed at a discharge rate of 0.13-45 ml/min, while rotormix enables shot sizes from 0.006 ml (6 μl) to be processed at a discharge rate of 0.26-90 ml/min. In both cases, this is dependent on the viscosity and, in the case of rotormix, also on the mixing ratio. Metering precision is ± 1 per cent.

Reliable material supply
With rotordis and rotormix, materials with different viscosities can be processed, ranging from water-thin to highly viscous or pasty. Depending on the viscosity, cartridges, pressure tanks or barrel pumps can be used. With both systems, application is generally carried out directly from the metering system onto the component by means of a nozzle or mixing tube. A DC drive enables dynamic metering and a controllable back suction effect. This ensures a clean thread break at all times. A specially developed electronic metering control unit ensures optimal adaptation of all application-specific parameters. In addition, straightforward integration into automated production processes is ensured thanks to a standardised interface.

Characteristics and Main Parts of Screw Pump

 

t's a screw pump's spinning component. The driver screw connects to the motor's driving shaft. It aids in the consistent volumetric flow rate of fluid pumping. The timing gear is connected to one end, while the drive shaft is connected to the other.To get more news about screw pump stator, you can visit hw-screwpump.com official website.

The driven screw is rotated by the driver screw, which is powered by the motor's driving shaft. It has a good fit with the driven screw. High-tensile steel is used to make this screw. The driver screw's main job is to rotate the driven screw through a timing gear, which is an intermediary component.

Driven Screw
High-tensile steel metal is also used for the driven screw. Because of the movement conveyed by the timing gear, it rotates around its axis. It spins in the opposite direction as the driver's gear. The clearance area of this screw is constant. This aids in catching water inside the restricted space.

The water volume decreases and travels toward the outlet port as the driver and driven screws move together. The fluid's pressure rises as a result of this movement. It then discharges through the discharge/outlet port.

Timing Gear
The timing gear drives the driven screws in such a way that the female and male rotor assemblies do not make metal-to-metal contact. It establishes a link between the driver and driven screws. The driver screw rotates the timing gear, which then transmits that rotation to the driven screws. It drives screws in this manner. Even if the pump is turned off for a short time, it guarantees that no such connections are made.

Inlet & Outlet Ports
The intake and exit ports of a screw pump are distinct. The water is sucked into the pump through the intake port, and it is discharged through the output port. When the pump ultimately stops, the inlet and output are designed to ensure that there is enough liquid medium. This aids in the delivery of the pump's initial liquid medium. As a result, the suction tube should not dry out quickly, even if it is empty or dry.

Pressure Relief Valve
Screw pumps are a type of positive displacement pump that builds pressure even while the outlet is closed. This builds up pressure, which can lead to major problems including pump internal part damage and harm to the pump operator. As a result, every positive displacement pump has a relief valve to safeguard the pump, the operator, and any associated gear. Extra pressure is returned to the intake using this valve. Recirculating the exit fluid is another well-known method of reducing extra pressure.
Bearings
During pump operation, the top bearings of a vertically mounted screw pump sustain heavy loads as well as axial and radial stresses. As a result, the load on the lower bearings is minimal.

The bottom bearing's primary function is to keep the pump's components aligned. Water screw pumps, roller bearings and slide bearings mounted in parallel, on the other hand, they have relatively low loads. This is due to the fact that the generated radial and axial forces are opposed and cancel one another out.

Driving Shaft
The driving shaft links the pump assembly to the drive motor. This connection is made possible by the use of the proper set of flexible couplings.

This driving shaft is a critical component of many types of pumps, and it goes from side to side to ensure the driver screw's operation. The driving shaft is secured by a set of bearings that fit in the axial direction in such structures. As a result, accurate driving shaft alignment is critical to preserve the pump's service life and bearings.

NEW PROGRESSIVE CAVITY PUMP DESIGN IS EASY TO MAINTAIN

Progressive cavity pumps have their place in pumping systems. But man, are they a bear to work on. Netzsch just released a new progressive cavity pump design that takes about 90% of the hassle out of maintaining their progressive cavity pumps.To get more news about progressive cavity pump rotor, you can visit brysonpump.com official website.

WHAT IS A PROGRESSIVE CAVITY PUMP?

In case you're not familiar with them, progressive cavity pumps are best suited for shear sensitive applications, like transferring fruits and vegetables. They're also great for handling abrasive and corrosive fluids.

At the heart of every progressive cavity pump is a rotor and stator. As the single helix rotor revolves eccentrically within the double helix of the stator, a continuous cavity is formed and progresses towards the discharge end of the pump as the rotor rotates.

If you've ever worked on a progressive cavity pump, you know how difficult it is to replace the rotor or stator if something fails or the pump runs dry. The whole pump must be removed, repaired, and realigned after being reinstalled. It is a very tedious and time-consuming job.
This is really where Netzsch's NEMO FSIP Progressive Cavity Pump shines. FSIP is an acronym for Full Service In Place, meaning you can service the pump while it is installed. Its design has been re-engineered to provide full access to all the wear parts without requiring any special tools. You can simply remove and replace all rotating parts without having to disconnect the pump from the piping or having to remove the motor.Netzsche NEMO FSIP Progressing Cavity Pump

The NEMO FSIP unit is especially useful where pumps are installed in wear-intensive environments requiring more service and maintenance work. The workload required to repair this pump is minimal, saving time and increasing profitability. We saw how easy it is to service this pump at WEFTEC 2015. Watch the demo video below to see for yourself.

Improved progressing cavity pumps from NETZSCH

NETZSCH Pumpen & Systeme GmbH have added another component to their range of NEMO progressing cavity pumps. The new xLC stator adjustment unit is said to triple the service life of the pumps, particularly when conveying difficult, abrasive media. To get more news about screw pump, you can visit hw-screwpump.com official website.

When wear occurs in the rotor-stator system, the xLC unit allows the performance of the pump to be re-established by adjusting the preload between the conveyor elements.It is important for the xLC adjustment system that the elastomer in the rigid metal sleeve of the stator is flexible, which has been made possible with the development of the proven iFD stator 2.0 component.

The xLC unit uses this characteristic so that the elastomer is not vulcanized into the housing, but rather fixed through axial pressing. To regulate the preload in the rotor-stator system, the elastomer in the sheath is extended (by pulling) or shortened (by pressing), which changes the preload between the pumping elements.

In case of wear, compressing the elastomer increases the preload and re-establishes the reduced sealing line. If the stator has to be adjusted due to declining pump performance, the setting nuts of the system are adjusted, compressing the elastomer insert in the metal housing once again.

A scale with seven defined stop points facilitates gradual adjustment of the stator with only two setting screws while also showing the remaining potential until a stator change is required.

FISH FRIENDLY SCREW PUMPS

The concept of an Archimedean screw is over 2000 years old, and has many uses in modern life, however it is commonly used in a trough for moving water. This often makes the cost of their use prohibitive, due to complicated construction and restrictions on size. Along with this, wear levels are high, and leakage down the screw can reduce their efficiency,
meaning larger sizes are specified to achieve the desired result.To get more news about screw pump rotor, you can visit hw-screwpump.com official website.

Fish Flow Innovations have revolutionised the use of Archimedean Screws by being loyal to the original concept of using the screw in an enclosed tube- this way every drop that enters the screw is moved to the top, vastly improving efficiency, with obvious knock-ons to running costs, reducing size of the pump, and even savings in construction of the surrounding buildings and civil structure.

The design is simple, yet very clever, using high grade materials such as Stainless Steel and Vinyl Ester Composite to keep weight low, preventing osmosis-related damage and ensuring a long, trouble free life. A major factor in it's efficiency is that there is no leak path, with no requirement for seals that can wear on the screw vanes, meaning that EVERY drop that goes in, is pushed out at the top.

The pump is delivered as a single module, can be installed in a matter of a few hours, and requires an extremely simple civil structure, vastly reducing site costs when compared with a traditional screw pump.
The ACE archimedean screw pump has been developed in the Netherlands by Fish Flow Innovations, with the key design criteria being absolute safe passage for fish that enter the pump. In developing a specifically designed leading edge for the pump, benefits in efficiency and energy savings were also noted, making the pump the perfect solution.

The leading edge has a curved vane, which glides smoothly into the water to reduce splash and turbulence, and in turn it hydraulically guides fish and debris into the screw pump preventing collision. The smooth entry into the water also prevents direct strike as found with common screw designs, and the lower speed that is required due to the increased efficiency also helps to preserve fish in the area. The pump has an in-built reverse facility that on stopping the pump, it is allowed to back-wind for sufficient rotations to empty the pump prior to applying the brake, allowing any aquatic life that remain in the pump to escape.
The Fish Friendly Screw pump is designed to be extremely simple to install, where in most cases the pump can be installed in a matter of hours. Where typical screw pumps require weeks of complicated and intricate construction of a concrete half-pipe, the Fish Flow Innovations Screw Pump only requires a horizontal apron, and a vertical wall to sit on. The unit is supplied on a fabricated frame, which merely requires bolting to the concrete surface, with electrical connection finishing the installation.

The pump has no limitation in length- typical screws are limited due to their weight, causing sag, which often requires an inefficient slope angle to be used- the FFI Screw pump can have intermediate supports keeping the build height low
If used with a non return valve for peace of mind, the FFI screw pump is capable of pumping into a head of water, again keeping the build height low
The increased efficiency reduces the overall size of the pump- all other constructions can be smaller to suit
Common practices involving fixed speed pumps may require multiple pumps to be used- Variable speed drives often mean less pumps can be used, and run at the minimum energy output require to achieve the desired flow

The Safe Use Method Of Screw Pump

 

, screw pump stop

 

When the screw pump is stopped, the discharge stop valve should be closed first, and the suction stop valve should be closed after the pump is completely stopped.To get more news about screw pump, you can visit hw-screwpump.com official website.

Screw pump because of the large working screw length, rigidity is poor, easy to cause bending, resulting in work disorder. The connection of the shafting must be well aligned; In the work is best to be carried out after installation and positioning, so as to avoid deformation caused by pipeline involvement; Connect the pipeline should be fixed independently, as far as possible to reduce the pump. In addition, the spare screw in the preservation of the best suspension fixed method, to avoid the deformation caused by uneven placement.

2, the start of screw pump

Screw pump should be in the suction stop valve fully open in case of overload or suction.

Screw pump although has dry suction ability, but must prevent dry turn, so as not to scratch the working surface.
If the pump needs to start in the oil temperature is very low or viscosity is very high, the screw pump should be in the suction valve and bypass valve fully open in the case of start, let the pump start the lowest load, until the prime moder reaches the rated speed, then the bypass valve gradually closed.
When the bypass valve is started, the liquid is constantly circulating in the pump under the condition of throttling, and the more circulating oil, the longer the circulation time, the more serious the heat of the liquid, and even the pump due to high temperature deformation and damage, must be paid attention to.
3, screw pump operation

The screw pump must be operated in a given direction to produce a certain suction.

Pump work, should pay attention to check the pressure, temperature and mechanical shaft seal work. The shaft seal should be allowed to have a trace of leakage, such as the leakage amount does not exceed 20~30s/ drop, it is considered normal. If the screw pump in the work of noise, this is often due to the oil temperature is too low, the oil viscosity is too high, the oil into the air, coupling loss or excessive wear and other causes of the pump.

Positive displacement pumps include progressive cavity pumps. By forming a sequence of cavities in the fluid that enlarge as the pump advances, they are used to transfer fluids. Because they can produce more force and more cavities than other types of pumps, this type of pump is frequently employed to transfer thick or viscous fluids. A mechanical tool used to transfer liquids or fluids is called a single screw pump. It is made up of an impeller, a suction valve, a discharge valve, and one main shaft that connects all the parts. This kind of pump's operation is based on a straightforward air displacement procedure.
Positive displacement pumps can be classified as progressive cavity pumps, eccentric screw pumps, or cavity pumps. While the rotor of a progressive cavity pump turns, a series of small, distinct cavities with set shapes advance through the pump, transferring fluid at a volumetric flow rate that is proportionate to the fluid being pumped. These pumps are used for metering fluids and pumping materials that are abrasive or sensitive to shear. As they approach their termination, the cavities overlap. The demand for progressive cavity pumps from the water and waste-water industries is rising as a result of their ability to handle very viscous fluids, which is one of the market's major growth drivers.

Progressive Cavity Pump Systems: When Precision and Repeatability are Vital

 

As recently as half a decade ago, operators of manual and automated dispensing lines had little ability to achieve highly accurate, consistent applications of adhesives, epoxies and other fluids, especially when desiring small depositions, working with viscous materials, and/or when attaining the fastest possible throughput speed was a priority.To get more news about Progressive cavity pump part, you can visit brysonpump.com official website.

For example, jetting valves-perhaps the gold standard for high speed, micro-deposit application capabilities-can be unsatisfactorily turbulent in their accuracy. Time/pressure dispensers and auger valves can deliver accuracy down to ±10% and ±5% respectively, but have a variance that might be unacceptable for many operators, with deposit size impacted throughout the process by temperature-driven changes in material viscosity, as well as fluctuations in air pressure created by the changing fluid level in the syringe barrel. And, the original volumetric or positive displacement pumps such as piston and gear pumps, while delivering the ability to get closer to the "holy grail" accuracy level of ±1%, are often more limited in bead size range and can manifest speed deficits due to their need to fill and refill between depositions.

For many organizations, of course, these limitations-and the mandatory balancing act among variables-were, and continue to be acceptable, with the necessary compromises falling within their business operating goals. However, for an increasing number of companies in numerous highly competitive industries, where attaining the optimum levels of accuracy, consistency and speed can translate quickly into a stronger market position and greater profitability, the search for a superior adhesive and epoxy dispensing option continued.

Adapting progressive cavity pump technology to new applications

Looking to heavy industry such as oil drilling and cement processing, innovative dispensing equipment manufacturers noted the potential of progressive cavity pump technology, a unique type of positive displacement pump technology long proven in use in a number of critical applications, such as continually moving large volumes of heavy oils and slurries from deep underground. With the technology now successfully miniaturized and adapted to a table top or assembly line appropriate footprint, progressive cavity pumps offer a number of advantages over incumbent dispensing methods.

For example, unlike other types of epoxy and adhesive dispensing solutions, including other types of positive displacement/volumetric pumps and time/pressure valves, a progressive cavity pump is both a sealed system and a continuous flow operation. Progressive cavity pumps have proven their ability to dispense microbeads as small as a microliter, using a wide range of materials with viscosities ranging from 1 to 300,000 centipoise or more. And, since internal material flow is continuous, rather than relying upon a filling/refilling approach, throughput speeds are consistently high.

Most dramatically, however, progressive cavity pumps can deliver volumetric dispensing accuracy up to ±1%, and do so consistently, unimpacted by ambient temperatures and pressures that plague unsealed pumps that are exposed to environmental conditions, or by variations due to changing material volume levels during operation.
How it works

The essence of a progressive cavity pump is that it operates by use of a continuous rotor/stator configuration, rather than by having material being ejected from filling/refilling chambers at fixed, separate intervals. In this technology, the feed fluid-from plain water all the way to high viscosity greases or solders-is held in a reservoir under positive pressure supplied by an air line which forces it out of the barrel into the fluid feed path and then to the rotor/stator chamber assembly.

The metal, single-helix rotor continuously turns inside a flexible rubber stator molded with a twin helix shaped aperture, forming a constantly shifting series of tightly sealed cavities which move a precise, consistent volume of material steadily and continually toward the pump outlet. From there, fluid is driven to the dispense tip outlet with a flow rate dependent upon the rotor rotation in the feed direction, precisely controlled by the desired specifications dialed into a proprietary controller paired with the system. Of note, with this technology the flow rate is adjustable at any time by changing the motor speed on the controller, as opposed to having to stop operation to adjust the pump itself, further enhancing speed and flexibility. The fluid is dispensed from the tip by means of a voltage signal applied to the motor, and shearing is achieved by reverse Z-motion/tip retraction.

Stators for eccentric screw pumps

In the field of materials handling, progressive cavity pumps are successfully used for tasks that exceed the technical possibilities of pumps of conventional design. They have decisively expanded the range of available conveying systems and are used for conveying highly viscous, abrasive and corrosive media. The components of the progressive cavity pumps are the fixed stator and the rotating component, the rotor. Rotation and the design of both components create chambers through which the respective media are transported from the suction to the discharge side of the pump. To get more news about screw pump stator, you can visit hw-screwpump.com official website.
Stators consist of a steel jacket lined with rubber. The composition of the rubber compound in the stator depends on the requirements of the progressive cavity pumps and the medium to be pumped.

In materials handling technology, not only the abrasion behaviour but also the given physical, chemical and thermal medium properties are important factors that affect the composition of the material in the stator. The rubber mixture is therefore composed in such a way that the material wear of the stator is kept as low as possible. This increases the service life of your stators and prevents costly failures.
In paper mills, pulp, groundwood, glue and paint must be conveyed by means of stators. These are media of crumbly consistency, medium to high viscosity and chemical aggressiveness. The stators from Artemis guarantee a long service life of the progressive cavity pumps.In the food industry, eccentric screw pumps are replacing old, manual processes in the harvesting of grapes, fruit and olives. They are also used in the dairy industry or in the confectionery industry to convey highly pasty masses such as chocolate, marzipan and dough. Our materials and stators used in the food industry meet the strict requirements and quality standards of the food law thanks to our quality controls.
Petroleum industry
Downhole pumps in the field of crude oil production offer a high degree of economic efficiency compared to traditional pumping equipment. Thanks to their easy installation and maintenance, good controllability and high efficiency under difficult pumping conditions, there has been a worldwide increase in the number of pumps. To reduce long downtimes and costs caused by premature failures, we have developed special abrasion-resistant materials for the stators of the downhole pumps. The geometries are fine-tuned to the expected geological temperatures. We offer you complete systems as well as a relining service for worn stators.
Dosing technology
In the electronics industry in particular, ever smaller components must be bonded or encapsulated. One of the main tasks of stators is therefore to convey very small quantities of various media with a high degree of repeat accuracy without dripping. Due to the composition of the materials specifically adapted to the media, our stators achieve the highest possible chemical resistance!

Construction industry
Especially in the construction industry, the screw conveyors have to convey extremely abrasive substances. Artemis offers stators of various designs with a rubber or plastic casing or slotted steel tube for retensioning to prevent wear and tear of the progressive cavity pumps as far as possible. We develop solutions for you so that we achieve an optimum service life for your progressive cavity pump!

Chemical industry
In the chemical industry, the resistance of the stator's elastomer must meet the highest demands. Media to be pumped can be all kinds of substances, such as filter cake, which has hardly any liquid properties, sludge and many other chemical substances. Our sales teams and laboratory technicians will support you in selecting the appropriate compounds for your application. Our resistance list has proven to be a useful tool in this context.

DOES YOUR PROGRESSIVE CAVITY PUMP NOT START?

These positive displacement screw pumps are great for moving thick paste-like fluids at an even speed and pressure but are often problematic with abrasive and aggressive waste-streams.To get more news about Screw pump rotor, you can visit hw-screwpump.com official website.

Whatever your application, if you have an issue with a faulty progressive cavity pump try this checklist for possible solutions.

Here's our trouble-shooter for a variety of progressive cavity pump (screw-pump) issues:

Check the power supply matches the pump motor voltage and amps.
Check that the fuses haven't blown.
Has the pump been idle for some time? The rotor and stator may have ‘bonded', if it doesn't turn then check for dried debris and lubricate with an appropriate oil or glycerin.
Has the cable or its connections been damaged? If so, have the damaged section replaced.
Check that the motor windings haven't burnt out.
Have the pumped fluid's properties changed? Tight tolerances on progressive cavity pumps mean that if the media's viscosity or temperature do not match the pump's specification it can lead to thermal expansion. This could burn the rotor and stator where they rub or even jam it, stopping all movement and putting strain on the motor.
Examine the rotor to make sure it's not blocked or jammed. If it is, then withdraw it from the pump, clean down and if there is no damage evident, reassemble.
Try reducing the pump's rotation speed before switching it on, also check the delta start settings if it is an older 3-phase motor, or invertor settings on a newer 3-phase. Generally, the larger the motor, the longer the time delay between start up and full power is needed. If the pump starts okay on a low speed, wait until it has discharged steadily for a time before increasing speed step-by-step to normal operation.
IS THE PUMP GIVING TOO LITTLE OUTPUT?

Check the feed intake is supplied and that the pump's inlet is fully submerged. Stop the pump and isolate the power while you check for blockages at either end.
Check the motor is rotating in the correct direction. If not, the wiring needs correcting before it is started up again.
Has performance reduced over time? Check the wear parts and replace them if worn out. Progressive cavity pumps rely on tight tolerances and abrasive slurries can soon wear down the stator walling and rotor edges.
Examine the discharge pipework and replace it if leaking or cracked.
Another reason why the pump may be giving too little output is if the final discharge head is too high; where this is the case, you may need to use a larger pump or an alternative type.
Check that the rotation speed is correct. Reduced speed for the same power draw could indicate something jamming inside the pump, or the fluid's viscosity is too high for the pump configuration.

The screw pump: Function, areas of application and special features

"Screw pump" is short for eccentric screw pump. After the inventor, it is also known as the Moineau pump , or from English as the PCP pump (progressive or progressing cavity pump). It is one of the rotating positive displacement pumps. The pumped medium is transported from the upper tank through the hose to the spray lance.To get more news about SEEPEX Pump Parts, you can visit hw-screwpump.com official website.

The eccentric screw pump has two main components: on the one hand the rotor, a rotating screw, and on the other hand the stator, a cylinder in which the rotor is located.

The stator has a similar internal geometry to the rotor ,both are helical. When the rotor rotates in the stator, defined empty spaces (conveying chambers) with circumferential sealing result, thus creating a negative pressure. This in turn ensures that the eccentric screw pump is self-priming. Due to the constant movement of the rotor (in contrast to changes in direction of reciprocating pistons and thus corresponding dead centres), material conveying is low in pulsation. At the injection lance, the medium is then divided with the aid of compressed air and can be applied evenly.

Valves for limiting the delivery spaces do not exist in this pump, which means less wear. The rotor moves eccentrically, which means that the axis of rotation of the rotor does not correspond to the axis of symmetry of the complete pump. This is also where the name of the eccentric wrom pump comes from. The eccentric screw pump should not be confused with the Archimedes screw, which is also called a screw pump and is used today especially in the conveyance of solids such as bulk materials. This is a huge helix that simply pushes the conveying elements (often solids) upwards in a trough. There is no stator in which negative pressure is generated, so that this type of material conveying does not belong to the pumps, but is a constant pressure hoist. It was originally used as a water lifting device in ancient times to pump water.
Due to the rotor-stator principle, the WAGNER screw pumps are very easy to operate and infinitely variable and are also suitable for beginners in the field of machine processing. We also make a point of ensuring that our machines are as trouble-free and easy to use as possible for your users - accordingly, WAGNER mortar spraying equipment can be dismantled and reassembledin just a few steps, even on theconstruction site itself. All the wetted parts are made from stainless steel.In addition, our PlastCoat and PlastMax units have a long service life.They are very robust and particularly low-wear and low-maintenance, and the uncomplicated operation avoids sources of error and thus potential for damage. Our WAGNER screw pump also works much more quietly than the standard piston pump!

The screw pump combines many advantageous features of other pump solutions: Like the centrifugal pump, for example, it has no pressure or suction valves, and like a piston pump, the eccentric screw pump also has excellent pumping speed. The flow rate is constant and speed-dependent.Like a gear or screw pump, it handles pumped material with high viscosity, grain size,fibres and inhomogeneous or abrasive materials.

Spraying particularly heavy materials such as plaster or filler is hard work. The biggest advantage of a screw pump is the possibility of achieving a high working speed and yet a high-quality surface result with little physical effort due to the machine processing . The quality of your work does not decrease, on the contrary, and in addition you can plaster, fill, coat or reinforce surfaces much faster. The more surface area involved, the more obvious the time and material savings.

What are rotor stator pumps, and how do they work?

 

Rotor Stator pumps are progressive cavity pumps - a type of positive displacement pump. They can be used for pumping various viscous and abrasive fluids. To get more news about SEEPEX Pump Parts, you can visit hw-screwpump.com official website.

The fixed stator and the rotating component, the rotor, are the yin and yang of progressive cavity pumps. The rotor is the spiral steel shaft that creates conveying chambers of the inner outline of the rubber tube. Stators are metal tubes with internally molded cavities made of synthetic or natural rubber.

When the rotor is triggered, the conveying chambers move in the direction of flow. This is how the constant flow of material is achieved. The rotor takes a form which resembles a corkscrew, which, combined with the off-center rotary motion, gave its alternative name: eccentric screw pump.
2. What are rotor stator pumps used for?
Various industries use progressive cavity pumps. Putzparts is specialised in rotor stators for the construction and refractory industry to pump screed, mortar, grout, gypcrete, plaster and fireproofing cement.

Rotor stators also cater to wood processing and cellulose production, the chemical industry, the petroleum industry, domestic and industrial sewage, and low flow, high head, and agricultural water pumping.

3. What are the relevant factors when choosing the rotor stator?
Size, diameter, grain of the material, and the flow rate you want to achieve

You will want to choose your rotor stator based on its size and diameter, depending on the grain of your material and your desired flow rate. Different rotor stator pumps to suit different materials and purposes and achieve different pumping results. Different flow rates and pressure stabilities are achieved by varying designs of screw pumps.

4. Maintenance-free or clampable rotor stators?
Maintenance-free stators are more user-friendly. They can be used directly after being installed in the machine. They have unslotted steel tubes as outer casings. This means they allow for constant delivery pressure and support a hassle-free process.

Clampable stators are clamped according to material and grain size. They come in two types: stators with built-in tensioning clamps and slotted stators that are provided with an external tensioning strip.

Both transport diverse materials smoothly, continuously and with minimum pulsation. Pumps which require clamping have an integrated clamping bar or a grooved stator for the clamp, with or without an additional separate clamp. When the delivery pressure drops, the stators must be retightened.

5. How to choose the right shore for your rotor stator?
The shore is very significant: the smaller the number of the shore, the softer is the rubber. We recommend a soft rubber if you pump material with sharp aggregates, as they wear out less quickly.
6. Does Putzparts supply high-quality rotor stator pumps?
Putzparts rotor stators are made in Germany. Our high alloyed steel rotors are never hollow. We use precisely drilled, high-quality steel for long-lasting rotors.

Our stators use high-endurance rubber, which makes them long-lasting, reliable, and supportive of a solid, consistent pumping experience.

7. Can I use the pumps for different machines?
We provide Rotor Stator Pumps for various machines by Putzmeister, PFT, M-Tec, Uelzener, Turbosol, Mai, Utiform, Inotec, Imer, Brinkmann and many more. Many machines use the same rotor stator types.

For plaster, the most popular pump is the D6-3, which has a solid output of 30 litres per min at 400 rpm. If you need more, you can go with the D8-2, which has more output at 66 litres per minute than any other D-pump.

Function of a Multi Screw Pump

 

Flexible, efficient, reliable: Multi screw pumps offer a precise and reliable way of pumping the most demanding media in various applications. But how does a multi screw pump work, and for which applications is it particularly suitable?To get more news about screw pump stator, you can visit hw-screwpump.com official website.

As a global specialist in complex fluid management, NETZSCH Pumps & Systems has answers to all your questions about positive displacement pumps. We will show you the function of a multi screw pump and how to benefit from it.
Four elements are indispensable for the function a multi screw pump: The screws, also known as rotors, the pump housing, the drive or gearbox and the mechanical seals. NETZSCH offers you screws in a wide variety of designs, depending on the application. From nitrated steel alloy to stainless steel, everything is available. The screws are manufactured with a highly efficient profile. This allows you to achieve a high flow rate with low fluid shear. In addition, several pitch variants are available, which are balanced and ensure a high suction capacity. Another advantage offered by NETZSCH multi screw pumps is the innovative FSIP? design. This allows you to quickly and easily disassemble and assemble the pump without separating it from the pipeline. Thus you save time and, as a result, money. Another critical component for the function of the multi screw pump is the drive and the gearbox. The gearbox ensures smooth torque transmission between the screws and, together with the drive, guarantees contactless operation of the pump elements. This results in slight vibration and low noise generation, therefore making it possible to pump almost noiselessly. The mechanical seals also play a decisive role in the smooth functioning of a multi screw pump. NETZSCH offers single- or double-acting mechanical seals in cartridge design. Both are interchangeable and fit into the same mechanical seal housing. In addition, a pressure flush or a quench connection is optionally available. This allows you to clean the pump easily without removing it from the system and to pump the medium at a constant temperature.

Multi screw pumps belong to the group of rotating positive displacement pumps. The form of the rotors resembles a spindle screw. It consists of at least two counter-rotating rotors and a housing enclosing them. The screws are designed with a regular, thread-like profile and interlock like gear wheels. The cavities created by these three construction elements form the feeding chambers. While the rotor rotates, the chambers move out in one direction, conveying the medium from the suction side to the discharge side. Due to their design, multi screw pumps offer a constant and precise delivery rate, are relatively noiseless and have high efficiency.

Multi screw pumps are used in a wide range of applications, especially in situations where precise and reliable fluid delivery is required. Applications range from food production and the chemical industry to oil and gas production. For example, multi screw pumps convey liquids such as dairy products, juice concentrates and syrups in the food and beverage industry. But they are also used in the pharmaceutical industry to convey medication, ointments and lotions. Due to the innovative design, you can clean the multi screw pumps particularly easily (CIP - "Cleaning-In-Place-Procedure") and even keep them sterile (SIP - "Sterilisation-in-Place-Procedure"). The concept allows you to clean without an auxiliary system and without time-consuming removal from the system. This also makes multi screw pumps ideal for use in the chemical industry, where they convey liquids with high viscosities and aggressive chemicals. In the oil and gas industry, multi screw pumps pump media such as crude oil, refinery waste and lubricants. All in all, multi screw pumps offer a precise and reliable way of pumping liquids. Especially in applications with a high viscosity or an aggressive chemical composition of the medium, multi screw pumps are ideally suited.

Bauer BG Series Geared Motor for Wastewater Eccentric Screw Pump

Eccentric screw pumps at the sewage treatment in Bayreuth, Germany operate almost continuously 24/7/365. When it was time to replace the motor on one of the pumps at the site, the operators seized the opportunity, after a successful technology upgrade to their sedimentation tank drives (see P-8000-BGM), to specify an optimized replacement unit from Bauer Gear Motor.To get more news about SEEPEX Pump Parts, you can visit hw-screwpump.com official website.

Bauer was ready to offer an innovative permanent magnet synchronous motor (PMSM) solution that provided improved efficiency and increased cost-effectiveness. Working with the pump manufacturer, Bauer discovered that the installed 15kW IE3 asynchronous motor (ASM) could be downsized to a 5.5 Kw IE3 drive with PMSM technology.

The downsized motor provided significant energy efficiency. However, the exceptionally efficient rotor design of Bauer PMSM drives utilizes specialized permanent magnets, which provide additional power savings and improved environmental credentials compared to traditional motors.

Heat losses from the rotor are eliminated and total losses are reduced by 25%, which results in consistent motor efficiency improvements of over 10% compared to competitor drives. These characteristics ensure high efficiency, even across varied duty requirements. A minimum 10% overall efficiency improvement extending over yearly operating cycles delivered considerable cost savings of up to € 9.000 per pump per year along with reduced CO2 emissions.

Eccentric screw pumps operate at different speeds and operating points depending on requirement, which suits the wide partial load operation and speed range offered by the PMSM. Furthermore, this range offers a higher overload capability, which is advantageous if another pump fails on-site and the same duty requirements are spread across fewer pumps.

New generation of EagleBurgmann pump seals

These can be used to seal, among other things, chemical pumps, water and waste water pumps, circulating pumps and submersible motor pumps in numerous industrial sectors. The eMG1 is 100% compatible with the well-known MG1 standard seal. EagleBurgmann says it has been innovated in detail and functionally expanded. A vastly reduced outer diameter of the bellows support now allows direct support by a retaining ring or with the use of much smaller spacer rings. The optimized bellows shape improves the automatic alignment of the bellows on the shaft and minimizes stick-slip effects.Get more news about Submersible Pump Seals,you can vist our website!

EagleBurgmann says the profiled PEEK-PTFE disk ensures consistent centering across the entire pressure operating range, exhibits good sliding properties and safeguards the automatic alignment of the elastomer bellows in operation through continuous self-cleaning. The eMG is identical in construction with the eMG1, but has a 20% shorter installation length. This provides manufacturers with new opportunities in pump construction: e.g., a more compact design due to shorter shafts with the associated material savings and increased efficiency.

EagleBurgmann says the rotating unit is space-saving. The computed pre-modelled bellows design and the spring assembly have no excess lengths and the outer diameter of the bellows support was reduced to a minimum.

Three Misunderstandings About Mechanical Seals Of Submersible Mixers

As a mechanical equipment used in sewage treatment, submersible mixers have very strict requirements for mechanical seals . However,misunderstandings often occur about mechanical seals. For example:
1. The tighter the rotary face is, the better.Get more news about Submersible Pump Seals,you can vist our website!

In fact, a too tight rotary face is harmful and useless. First，it is to aggravate the wear between the sealing ring and the shaft sleeve, thus causing leakage prematurely; Second，it is to increase the resistance of the axial adjustment and movement of the rotary face, which cannot be adjusted in time when the working conditions change frequently; Third，the spring is easily damaged due to excessive fatigue; Last，it deforms the sealing ring and affects the sealing effect of the rotary face.

2. The tighter the stationary seat is, the better.

The stationary seat is basically in a static state, and the sealing effect will be better if it is relatively tight, but it is also harmful if too tight. First，the sealing ring will be deformed, which affects the sealing effect; second，if made of graphite, the sealing ring is generally so brittle that excessive stress can easily cause cracks; third, it is difficult to install and disassemble because the stationary seat is easily damaged.
3. The larger the spring compression, the better the sealing effect of the mechanical seal.

Excessive compression of the spring can cause rapid wear of the friction pair and instant burnout; excessive compression makes the spring lose its ability to adjust the end face of the rotary face, resulting in seal failure.

The Essential Role of Fuel Filter Housing in Vehicle Performance

The Fuel Filter Housing plays a pivotal role in maintaining the performance and longevity of a vehicle. It is a component that houses the fuel filter, a crucial part of the fuel system.Get more news about Fuel Filter Housing,you can vist our website!

The fuel filter housing refers to three components in an assembly: the Fuel Filter Head, which also includes the primer and fuel heater; the Water in Fuel Sensor, which screws into the bottom of the filter; and the Filter, also called a filter housing. The fuel filter sometimes has all-metal construction, but many engines, such as the Duramax engines, use a fuel filter made from a composite material.

Fuel filter housing is particularly important for diesel engines. Diesel engines have fuel injection systems built to very tight tolerances. If contaminants in fuel are not filtered out, they act as abrasives on the fuel injectors, wearing them quickly. Fuel injectors are expensive to replace, making the maintenance of the fuel filter very important.

If any component within the fuel filter housing fails, the engine will suffer. There are two ways the filter assembly typically fails: Seal Failure and Cracks in Filter Housing. Seal Failure refers to the o-ring seals at the top and bottom of the filter leaking. As the filter is under suction from the fuel pump, a leaking seal means air can enter the system, making the engine hard to start and causing rough running. Cracks in the filter housing can cause fuel leaks and immediately disable the vehicle.

There are various manufacturers of fuel filter housing, each offering unique features and benefits3. For instance, Dorman is a recognized brand that offers diesel fuel filter housing compatible with select Chevrolet/GMC models. On the other hand, companies like Croda Industrial Specialties offer solutions for wet processing of textiles to improve their performance and final product aesthetic effects.

In conclusion, the fuel filter housing is a critical component in a vehicle's fuel system. It ensures the cleanliness of the fuel, thereby protecting the engine from potential damage caused by contaminants. As technology advances, we can expect to see more innovations in fuel filter housing design and materials, further enhancing vehicle performance and efficiency.
