An oil-filled vacuum pump or suction nozzle is a device used in engineering to remove gases (create a vacuum) in a confined space. Pumps are classified based on their operating principle: volumetric, jet, ion-sorption, ion-magnetic, molecular, condensation, adsorption, and ionic.
The most important parameters of vacuum pumps are:
ultimate pressure (the lowest pressure that can be achieved with such a pump),
pumping speed and the relationship between this speed and pressure,
capacity (usually measured in m3 of gas pumped per unit of time).
