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.
