Oil sealed vacuum pumps

Reliable oil sealed vacuum pumps for sustainble operation in demanding applications.

Leybold oil sealed vacuum pumps are used in all areas of vacuum engineering and are equally suited for both industrial production as well as research applications.

Oil sealed vacuum pumps are preferred for their reliability, low cost, and proven technology. The use of oil enables higher compression ratios and a better internal cooling behaviour. Oil sealed vacuum pumps have proven their performance in harsh applications such as food, heat treatment, coating as well as proven reliability in long cycle applications such as mass spectrometry.

Of the various vacuum pump technologies, rotary vane pumps are considered positive displacement pumps. These pump work by mechanically trapping a volume of gas and moving it through the pump, creating low pressure on the inlet side.

They are often called “wet” pumps because the gas being pumped is exposed to oil which is used as a lubricant to achieve a lower ultimate pressure....
