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

  • Separate variable speed drive (VSD) for each pump: stable vacuum level, balanced operating hours
  • Easy maintenance: access to each pump without stopping the system
  • Complete system on one base frame with common intake and exhaust manifold
  • Sound-insulated enclosure
  • HEX@ controller with configurable, web-based interface
  • Dry-running claw technology: oil-free pump chamber
