About the series

Technology and features

Operating principle

Claw vacuum pumps were developed for industrial applications that require constant vacuum, high pumping speed and completely oil-free compression. Two claw rotors running without contact compress the air without oil or other operating fluids in the pump chamber, which saves a considerable amount of energy compared with conventional designs. Explosion-proof versions are available for many series.

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

Features of the series

  • Also available with IE4 motors of the highest efficiency class
  • Single-stage, dry (oil-free) mono claw pump; contact-free internal parts without wear
  • Modular design: pump chamber accessible for cleaning without touching the gearbox and timing
  • Newly developed, integrated silencer; compact footprint
  • Lower internal temperatures extend the service life of the lip seals and prevent oil leaks
  • Corrosion-resistant claws and coated pump chamber as standard
