Claw vacuum pumps. C series

Description Claw vacuum pumps. C series

The claws of the C-Series feature an optimized, high precision on shape-claws roll together without contact, synchronized by a precision gear set. The compression is contactless and oil-free. Special seals separate the compression chamber and gearbox. 

The claw rotors control the transportation of the compressed gas 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 outstanding feature of this technology. . Elmo Rietschle holds  the patent on the newly designed triple lobe rotors with medium air compression; for the first time, vacuum and pressure are being created in one stage, simultaneously.

Advantages of claw vacuum pumps:
- Dry, contact-free operation
- Process safe and reliable
- No oil in the compression chamber
- Variable speed drive available
- Low sound level
- No greasing of bearings
