Performance of Polypropylene Melt Pump

Polypropylene melt pump is a polymer melt with high temperature and high viscosity. Therefore, the first requirement is that the pump has high temperature resistance, that is, at working temperature, all parts of the pump should have sufficient strength and stiffness, parts subject to alternating load should have high fatigue strength, wear parts should maintain high hardness and wear resistance. The expansion coefficients of each mating part should not be too different. Secondly, the pump is required to have good corrosion resistance.

 Thirdly, reliable sealing must be ensured. Fourthly, the wear parts of polypropylene melt pump must have enough service life. The gears of high temperature polypropylene melt pump are usually straight teeth, helical teeth, herringbone teeth and helical teeth.
