    Becker’s screw vacuum pumps, designed for rough vacuum, and screw compressors are dry positive displacement pumps. They have two counter-rotating rotors and a housing that encloses the rotors. Thanks to the direct drive via an integrated frequency inverter, a drive gear is no longer required.

    The rotors are designed with a regular, thread-shaped profile and mesh with each other like cogwheels. When the rotors rotate, they move out in a machine direction and convey the medium from the suction side (inlet) to the pressure side (outlet). They rotate in opposite directions without touching one another or the housing.

    The working chamber of the machines is 100% oil-free, making them relatively maintenance free. The integrated speed control enables energy-optimised operation of the devices. Becker drives continuously adjust the volume flow to the demand. It‘s high efficiency results into low energy consumption.
