Claw vacuum pumps. C series
Elmo Rietschle's dry-running claw technology generates contact-free vacuum or compressed air efficiently and economically due to the principle of internal compression. This leads to considerable energy savings, reduced power consumption, and lower cost of ownership overall compared to the traditional rotary lobe design without internal compression.
Claw vacuum pumps of the C series in continuous operation allow the following limit values to be reached: marginal residual pressure of 50 mbar, maximum overpressure up to 2.2 bar. Combined vacuum pump compressors provide a vacuum of up to -0.6 bar, and an excess pressure of up to 1.0 bar.
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
