Elmo Rietschle, R-WVB Series, Rotary Lobe Vacuum PumpsThe variable capacity R-WVB series rotary lobe vacuum pumps cover a range from 22 to 8,850 m3/hr and are available in 16 sizes.

Highly efficient and robust, these contact free operating triple lobe rotary blowers are designed for use with vacuum operations up to 0.5 bar (abs.). They are easy to service and emit only low noise levels and low pulsations.

Key Benefits

  • Dry running
    As dry running positive displacement rotary lobe vacuum pumps there is no need for oil or grease in the compression chamber.
  • Triple lobe technology
    Two non-contacting triple lobe rotors rotate against each other in the compression room of the R-WVB series vacuum pumps. The triple lobe rotors avoid pulsation problems while conveying air or gas mixtures.
  • Modular design
    These rotary lobe vacuum pumps are factory customised to meet the varying demands of each customer’s application. The blowers are available as basic units (one blower stage, no motor) or as compact units with or without acoustic enclosure.
