About the series

Technology and features

Operating principle

Roots vacuum pumps, also known as vacuum boosters, belong to the dry-running vacuum pumps. Together with a backing pump they cover a wide range of applications in which high pumping speeds are required. The two Roots rotors operate entirely without contact and without sealing liquid in the pump chamber; on most models only the timing gears and bearings are oil-lubricated.

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

Features of the series

  • Powerful: high pumping speed, favourable ratio of performance to size
  • Reliable: high availability thanks to condition monitoring with integrated sensors
  • Efficient: hermetically sealed synchronous motor (IE5) with frequency inverter, optimised rotor geometry, long maintenance intervals, canned motor without shaft seals
