Pumps • Vacuum Pumps • Rotary Vane Vacuum Pumps

A rotary vane vacuum pump is a positive-displacement pump that consists of a cavity in which rotor with mounted-on vanes rotates. It works as the vanes slide into and out of the rotor, creating seals along the edges and separate vane chambers. As the vane chamber on one side is filled with fluid coming from the inlet, it forces fluid out of the other chamber. Common uses for rotary vane vacuum pumps are high pressure hydraulic pumps and automobiles, which use them for supercharging, power steering, and automatic transmission. The pumps also drive gyroscopic flight instruments like attitude and heading indicators, and evacuate refrigerant lines in air conditioners and laboratory freeze dryers.
