Extruding gear pump is mainly used with squeeze molding machine and kneading machine. It reduces the discharge of volatility and instability, especially for single screw extruder, metering pump pressure is higher than the efficiency of single screw. So less power and heat is passed to the material. For high precision surface film extrusion line and product accuracy of extruder, increasing extrusion metering/turbo pump is necessary.
Structure of high strength and wear resistant material makes extrusion pump pump is widely applied in extrusion machine. For transporting natural rubber and soft PVC, can choose a special design of the pump. Batte unique structural design especially adapted to the fast color change materials frequently change extruder.
In extrusion machine, due to the extrusion pump inlet pressure is higher (i.e., screw output pressure), acting on the drive shaft of the driving side end face can produce high axial thrust, must eliminate the axial force. For this, extrusion pump drive shaft is designed to extend from both the left and right sides of the pump body and has a shaft seal, so that the drive shaft at both ends of the only under atmospheric pressure, axial force is able to eliminate.
