Operating Principle
Claw vacuum pumps and compressors feature two claw-shaped rotors. The rotors are mounted in a cylinder and move in opposite directions. The shape of these claw rotors extracts, compresses and expels the pumped medium.
The claw rotors do not come into contact with each other or the housing. The minimal clearance between the rotors and the chamber housing optimizes the internal seal. So, no lubricants or operating fluids are required in the compression chamber.
Claw vacuum pumps and compressors are driven by a directly flange-mounted motor. A synchronizing gearbox maintains precise rotor timing.
Operation as a compressor is also possible.
