The primary function of a melt pump is:
1. Significantly improves the stability of die pressure, thereby enhancing product quality;
2. It can achieve near-linear flow output and is easy to control;
3. Increase extrusion output and boost production;
4. Reduce the extruder load, save energy, and lower costs;
Installation Structure of the Melt Gear Pump
It is recommended to use a universal coupling to connect the reducer and the Melt Gear Pump, in order to eliminate the effects of thermal deformation. The Melt Gear Pump is a positive-displacement, forced-feed pump; its output flow rate can be adjusted by varying the pump’s rotational speed. It is recommended to adopt variable-frequency speed control, which can achieve nearly linear flow output from the gear pump.
