  The motor is coupled to the pump by means of a flexible coupling, Special Construction of this coupling and the use of specially selected materials ensures smooth and quiet running of the pump.  
     
 
The rotor is mounted eccentrically in the pump cylinders. The Three radilly sliding sliding vanes divide the pump chambers into three sections. Due to rapid rotation of the rotor the vanes are forced to slide against the cylender walls by means of centrifugal force. the pumping isbrought about by alternately increasing and decreasing the volume of the working spacewhich is of crescent shape in cross section. the component parts as the pump are sealed by Viton 'O' Rings. All parts are pinned to ensure easy disassembling and reassembling.
