Claw Vacuum Pumps And Compressors
The Elmo Rietschle dry claw pumps offer significant energy saving and high efficiency compared to the traditional rotary lobe blower designs without internal compression.
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.
Explosion proof versions with reduced leakage are available as well as ATEX compliant vacuum pumps and compressors.
