About the series
Technology and features
Operating principle
Oil-injected screw vacuum pumps compress the gas with two intermeshing screw rotors; the injected oil seals, lubricates and cools the compression chamber. An oil separator keeps the oil in the circuit. The design allows high pumping speeds with low energy demand and, on variable-speed versions, the pumping speed to be matched to the actual demand.
The technology page shows the operating principle with an interactive drawing: Screw vacuum pumps.
