Gear melt pump is melt pump with the gear structure. Gear melt pumps play roles of metering, pressurizing, and transportation through the gears. Gear melt pump is used for transportation, pressurization or the metering of the high temperature and high viscosity polymer melt, which is also called melt pump beacuse of the gear structure.
Gear Melt Pump Characteristics:
1.Gear melt pump output quantity is constant, regardless of the relationship between the friction and shearing taking place between the rubber compound and barrel wall.
2.Specific output will not change, and the increase in output temperature, due to heat generated by shearing, is small, even when extrusion pressure is increased.
3.Since the amount of heat generated by shearing is small even when the gear revolution speed is increased, the size of the temperature increase is small, and specific output remains unchanged.
In order to obtain an extruded profile of consistent quality, it is necessary to keep both the extruder output and melt viscosity constant. Batte melt pump is volumetric pump which meter polymer through a set of intermeshing gears，Which remove irregularity of flow in extrusion dies.
