HOME > PROJECTS > Vane Pump This product is a variable vane pump discharge. Configuring is the pump housing and an elliptical cam ring, the vane roter. the principle of the Extrusion is cycle of the pump housing by the principle of rotating the cam rings are made inside the vane. The variable pressure setting of pressure on the cam rings are made to change the principles. Set the pressure is greater than the cam ring to rotate the cam ring is smaller than the set pressure is stopped. Cam ring, automatically adjust the discharge pressure and can increase the efficiency of extrusion.
