Extrusion pump gear pump and main extruder and kneading machine with the use of. It reduces the fluctuation and instability of the material, especially for single screw extruder, which is more efficient than single screw. So the energy and heat of the material is less. For precision film extrusion line and product surface accuracy requirements are very high, an increase in extrusion metering / booster pump is essential.
High strength structure and wear resistant materials make the extrusion pump widely used in the extruder. For natural rubber and soft PVC, can choose a special design of the pump. The fast changing color structure design of Batte is specially adapted to the changing of the material.
In the extrusion machine, because of the relatively high inlet pressure of the pump, the screw output pressure, the driving shaft of the non drive side will produce a high axial thrust, must eliminate the axial force. Therefore, extrusion pump driving shaft design for from both sides of the pump body are extended out and the seal, and then the driving shaft at both ends of the only under atmospheric pressure, the axial force can be eliminated.
