Elmo Rietschle Liquid Ring Vacuum Pumps and Compressors

L-Series - Liquid ring solutions

Elmo Rietschle’s L-Series pumps and compressors utilise advanced liquid ring technology to deliver efficient and reliable performance in wet and abrasive environments.


The pump operates with an eccentrically mounted impeller that creates a liquid ring sealing the blades. Gas entering through the suction port is trapped and compressed as the impeller spins. This liquid ring design allows simultaneous vacuum and compression, delivering versatile, efficient performance across various applications.
