Oil-lubricated vacuum pump, suction unit – a device used in technology for removing gases (creating a vacuum) in an enclosed space. Pumps are classified by their operating principle as: positive displacement, jet, ion-sorption, ion-magnetic, molecular, condensation, adsorption, and ion pumps.

The most important parameters of vacuum pumps are:
- Ultimate pressure (the lowest pressure attainable by the pump),
- Pumping speed and how it depends on the pressure,
- Capacity (usually measured in m3 of gas evacuated per unit of time).
