In this article we will only discuss one and two-stage "medium vacuum" oil sealed rotary vane vacuum pumps that can produce a catalog ultimate vacuum of about 1 x 10-2 Torr (0.01 Torr or 10 microns) for a one stage model and about 1 x 10-3 Torr (0.001 Torr or 1 micron) for a two-stage model. We will review the Vee Belt Drive design and the Direct Drive design.
