Mechanical Vacuum Booster

Vacuum Booster pumps are commonly named as ‘Booster’ pumps on top of several types of bare pumps (e.g., rotary vane pumps, screw and liquid ring pumps) to improve ultimate pressure and pumping speeds. Roots(twin lobe) pumps employ two counter-rotating interconnecting lobes rotating within a body/stator.

Gas enters through the intake flange and is compressed between the two rapidly rotating rotors and the body wall, and is then expelled through to the discharge side.
