Key figures of the series

Operating principle

Liquid ring vacuum pumps, built with high-quality materials such as stainless steel and ceramics, are used predominantly in humid and wet processes. An eccentrically running impeller forms a liquid ring from the operating liquid, which draws in, compresses and discharges the gas. The pumps are extremely quiet, insensitive to condensate and low-wear.
