Dry Claw Vacuum
Pumps and Compressors

Principle of Operation

The main components of dry claw vacuum pump and compressor are two claws which turn in opposite directions in a housing. These claws are only separated from one another by a minimum gap and do not touch. Air intake is via a filter. The intake air is compressed by the special geometrical form of the claws and expelled at the delivery connection on the end. A synchronized gear ensures exact synchronism of the two claws.

Dry Claw Vacuum Pumps and Compressors

Principle of Operation

With claw vacuum pumps, two claw-shaped rotors turn in opposite direction inside the housing. Due to the shape of these claw rotors, the air or gas is sucked in, compressed and discharged. The claw rotors do not come into contact either with each other nor with the cylinder in which they are rotating. Tight clearances between the claw rotors and the housing optimise the internal seal and guarantee a consistently high pumping speed. A synchronisation gearbox ensures exact synchronisation 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.
