Dry Claw Vacuum Pumps

C Series – Dry Claw vacuum pump

Our dry running C-Series generates contact free vacuum or compressed air efficiently and economically due to the principle of internal compression. This leads to considerable energy savings compared to the traditional rotary lobe design without internal compression.

C Series – Dry Claw vacuum pump

Wide spectrum of performance

With the C-VLR claw vacuum pumps and C-DLR claw compressors the following ultimate pressures are attainable during continuous operation: vacuum up to 50 mbar (abs.) and pressure up to 2.2 bar. Combination pressure-vacuum pumps provide under-pressure up to – 0.6 bar and overpressure up to + 1.0 bar.

Innovative claw technology

The claws of the C-Series feature an optimized, high precision shape and roll together without contact, synchronised by a precision gear set. The compression is achieved dry and wear free. Special seals separate the compression chamber and gearbox. The claw rotors control the transportation of the medium by opening and closing the inlet and outlet channels. Thus, no sealing fluid within the compression chamber is needed. The overhung rotor design in all sizes up to model 300 is another
