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:

Operating Principle L-Series
Compression in L-Series pumps follows the liquid ring principleThe impeller is the only moving part inside the pump. It rotates without contact within the pump casing. A rotating liquid ring seals the impeller on the front and seals its blades against one another. In order to keep the liquid ring stable, liquid is also permanently sucked into the compression chamber and is output together with the conveyed gas.

The excentrical arrangement of the impeller within the casing creates variable compression chambers between the impeller blades during rotation, which causes the conveyed gas to be compressed within a full revolution.Since the pumps always create a pressure difference during operation, they can also be used as compressors when pumping gas from the surrounding atmosphere.The L-BV product line features a patented discharge-air cooling system which returns the condensate to the operating liquid.
