* High wear-resistance and elastic materials of stator allows the pump to handle various liquids with solid particles or fiber substances.
* Completely separate suction chamber and discharge chamber by spial sealing line enable the pump with the function of shut-off as valve.
* Inherent self-priming capability ensures the pump with a significant suction lift up to 8.5m.
* Constantly progressed cavity volume ensures a continuous non-pulsating flow.
* The capacity being proportionate to the speed realizes the flow control by speed governor.
