About the series

Technology and features

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.

The technology page shows the operating principle with an interactive drawing: Liquid ring vacuum pumps.

Features of the series

  • Single-stage liquid ring pump with flat port plate and variable port opening: stable pumping capacity throughout the entire rough vacuum range with economical operating water consumption
  • Compact pump element, robust and proven design
  • Impeller made of stainless steel as standard, corrosion-resistant
  • Monobloc design with lantern flange for automatic motor alignment and automatic centreline level setting during filling
  • Water as the operating liquid: isothermal compression, insensitive to vapour, condensate, liquid carry-over and particles
