ZM-TL Series Elastomer Gear Pump

The materials that the Melt Gear Pump can convey mainly include:

The primary function of a melt pump is:

1. Significantly improves the stability of die head 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, thereby eliminating the effects of thermal deformation. The Melt Gear Pump is a positive-displacement, forced-feed pump; its output flow 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.
