Bate melt pump is a special melt pump for pipes . It is mainly used for transporting, pressurizing and measuring high temperature and high viscosity polymer melt. Its main function is to pressurize and stabilize the high temperature melt from the extruder to keep the melt flow accurately and steadily into the extruder head. Nowadays, melt gear pump has been widely used in chemical fiber, granulation, plastic film, sheet, plate, profile, pipe, wire and cable, drawing, composite extrusion and othe
