With claw vacuum pumps, two claw-shaped rotors turn in opposite directions inside the housing. Due to the shape of these claw rotors, the air or gas is sucked in, compressed and then discharged. The claw rotors do not come into contact with each other or with the cylinder in which they are rotating. Tight clearances between the claw rotors and the housing optimize the internal seal and provide a consistently high pumping speed. A synchronization gearbox ensures exact synchronization of the claw rotors.
Claw vacuum pumps are driven by a directly flange-mounted asynchronous motor, with an efficiency class IE2. Claw vacuum pumps are ideally suited to use with frequency-controlled drives. Claw vacuum pumps are available in a wide range of sizes.
There are also variants for special applications such as dust and gas explosion protection, high steam contents, gas tightness and increased oxygen contents.
