Rotary vane vacuum pumps
Applications suction flow: up to 3000 m³/h vacuum: down to 1 mbarA, two-stage pumps able to reach pressures below 10E-6 bar How it works A rotary vane pump is a positive-displacement pump that consists of vanes mounted to a rotor rotating inside of a circular casing. The centers of these two circles are offset, causing eccentricity. Vanes are allowed to slide into and out of the rotor and seal on all edges, creating vane chambers that do the pumping work. As the rotor turns, centrifugal force causes the vanes to move outward, such that the outer edge of the vane stays in touch with the inside surface of the casing. In some cases the vanes can be tensioned. On the intake side of the pump, the vane chambers are increasing in volume ; On the discharge side of the pump, the vane chambers are decreasing in volume, forcing fluid out of the pump.
