Rotary Vane Pump

These pumps combine in them double features of suction & pressure and hence the same unit can be employed for either purpose. These have low oil consumption and are compact in design, noiseless & care free in operation and easily maintainable.
The main assembly consists of a stator with a rotor mounted eccentrically in it. The rotor is provided with eight vanes, which are free to slide and move in & out of the slots, by centrifugal action. When in 'out' position these press against the inner walls of stator. When the rotor rotates, these vanes sweep the air eight times in a single revolution creating vacuum & pressure simultaneously.
