Sliding vane rotary vacuum pumps

Operating principle: The MAPRO® vacuum pumps, BV series, are rotary vane machines, oil recirculating type.

In these vacuum pumps a cylindrical rotor turns eccentrically in a cylindrical stator of a larger diameter: the free space left between stator and rotor is half-moon shaped. Three slots are milled in the rotor and stratified plastic blades slide freely into the slots. The blades, as the rotor turns, are forced out against the cylindrical wall of the stator by centrifugal force, so creating individual “cells” whose volume changes continuously during the rotation.

Note: The system can be customized according to client

requirements, and competitive pricing is offered.
