Oil-lubricated vacuum pump, suction – a device used in technology for removing gases (creating a vacuum) in a closed space. Pumps are classified according to their operating principle into: volumetric, jet, ion-sorption, ion-magnetic, molecular, condensation, adsorption, and ion pumps.

The most important parameters of vacuum pumps are:

final pressure (the lowest pressure that can be achieved with that pump),
pumping speed and the dependence of this speed on pressure,
capacity (usually measured in m3 of gas pumped per unit of time).
