Our leading industrial dry running and oil lubricated rotary vane pumps cater for a wide performance range. The eco-friendly dry running rotary vane pumps are used for industrial vacuum, pressure and combined pressure and vacuum applications. Whilst, the time-tested oil lubricated rotary vane machines are typically used for generating vacuum. 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.
