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 Marvel of Vacuum Dry Ovens
A Vacuum Dry Oven is a versatile piece of equipment with a wide range of applications in laboratory research, engineering, and industry. It is most often used for delicate drying processes, such as drying tiny parts or removing flammable solvents. The low-pressure environment also minimizes oxidation during drying.Get more news about Vacuum Dry Oven,you can vist our website!

Fast and Gentle Drying
The vacuum oven ensures rapid and gentle vacuum drying. Its speed-controlled vacuum pump saves around 70% energy. The chamber load is not only dried at high speed but also extremely gently in our powerful and robust vacuum drying oven. Together with the speed-controlled vacuum pump, the vacuum oven forms an unbeatably energy-efficient duo.

Precise Temperature Control
Separately adjustable and directly heated thermoshelves ensure precise temperature control3. The temperature range of a standard vacuum oven can operate at temperatures as high as 200C to 250C.

Vacuum Cycles
When vacuum drying large quantities of powder or granulate, the vacuum cycles come into play perfectly. Two vacuum values can be set, between which the pressure is oscillated under controlled conditions. This way, a large amount of dry air is admitted within a short time, which absorbs humidity and is immediately extracted by the vacuum pump.

Energy Efficiency
The demand-oriented pump control ensures a significantly longer service life for the membranes3. The energy-saving potential is particularly impressive compared to an uncontrolled vacuum pump3. With representative measurements in ramp operation, energy consumption was around 70% lower, and even better values were achieved with a constant vacuum value.

Applications
The spectrum for vacuum drying in a vacuum oven ranges from foodstuffs to cosmetics, granulate, watches, books, printed circuit boards, to electronic components or injection molds3. Applications include drying, curing, aging, vacuum embedding, and plating.

In conclusion, the Vacuum Dry Oven is a marvel of modern technology, providing efficient, gentle, and precise drying capabilities across a wide range of applications. Its energy efficiency and versatility make it an indispensable tool in various fields.
