Extreme conditions, which prevail in humid and wet processes, lead to lime scale or abrasion, and hence to a considerable reduction in the performance of the pump. Elmo Rietschle liquid ring pumps, however, meet these challenges.The use of high-quality materials such as stainless steel and ceramics ensure utmost reliability and constant operating characteristics – for years to come.
Advantages at a Glance
Robust and economical
Dry running
Oil-lubricated gearboxes and bearings separated from the compression chamber
Modular design
Frequency control available
An oil-free vacuum pump, also referred to an oil-less vacuum pump or dry running vacuum pump, is essentially a pump that does not use lubricants in the chamber to create a vacuum or cool the pump. In oil-lubricated machines lubrication is used a seal the vacuum chamber and cool the pump. Oil-free machines use other means to cool the machine during operation such as water or air cooling.
