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.

Features of the series

  • Low-noise and low-maintenance
  • Bearing design for tight clearances and better pumping performance, mechanical seals
  • Interconnecting manifold as standard – small footprint
  • Water as the operating liquid: isothermal compression, insensitive to vapour, condensate, liquid carry-over and particles
  • Two-stage with efficient interstage separation for an optimum compression ratio
