Series melt pump for reaction kettle
Melt pump is used on extruder for transporting and metering high temperature and viscosity polymer melt ; at the same time, increase and stabilize the pressure of material from extruder then transport to die. Its capacity of stabilizing and metering kinds of plastics is better than kinds of extrusion. Melt pump also called metering pump, extrusion pump, gear pump, it is widely used in extrusion molding in plastic, resin, rubber industry. Now granulation, film, pipe, plate, sheet, and other industries; melt pump is the essential part of extrusion equipment, applied in PP, PS, PET, PVC, ABS, PE, PA, rubber, and etc.
Melt pump belongs to positive displacement gear pump, there is a pair of cylindrical gear with external teeth relative rotation to transport high viscosity melt fluids. There are straight tooth, helical tooth and herringbone tooth, three types of tooth to choose from. Every pair of gear is finished and assembled accurately to get precise flow rate. According to different extrusion situation, the pump and gear will do special disposition.Rubber Melt Pump

Melt pump advantages:
1. Stabilize the pressure of extruder from screw to die
2. Improve the product quality---- reduce the dimensional tolerance and waste, and then produce high precision product.
3. Improve the product quantity---reduce the pressure requirement to screw, from the original screw to mold head build pressure, change to melt pump to mold head build pressure, screw can increase the extrusion speed.
4. Reduce energy consumption per unit.
