Elmo Rietschle – C Series Claw

Description

The C-Series dry claw vacuum pumps and claw air compressors of Elmo Rietschle generate contact-free vacuum or compressed air efficiently and economically. This is possible because of the principle of internal compression in the rotary claw design. The gas is pre-compressed within the compressing chamber and is then discharged.

The Elmo Rietschle dry claw pumps offer significant energy saving and high efficiency compared to the traditional rotary lobe blower designs without internal compression.

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.
