About the series
Technology and features
Operating principle
Liquid ring vacuum pumps, built from high-quality materials such as stainless steel and ceramics, are used predominantly in humid and wet processes. An eccentrically mounted impeller forms a liquid ring in the operating liquid, which draws in, compresses and discharges the gas. The pumps are extremely quiet, insensitive to condensate and low-wear.
The technology page shows the operating principle with an interactive drawing: Liquid ring vacuum pumps.
Features of the series
- Bare shaft version for drive via coupling or belt
- Single-stage design with valve plate
- Mechanical seals flushed via internal channels – only operating liquid required
- Materials: grey cast iron, grey cast iron with stainless steel impeller, or stainless steel
