New range of single-stage oil sealed rotary vane vacuum pumps. Thanks to the optimized oil return system, there are no pressure fluctuations in the new “ES” pumps that are often seen in single stage pumps improving product quality and giving consistent process results.

CERN, the European Organization for Nuclear Research, has ordered 35 new “XDS” scroll pumps by Edwards, a leading manufacturer of sophisticated vacuum products and abatement systems and a leading provider of related value-added services.
