pellet extruder gear melt pump

The pellet extruder melt pump is a universal extrusion system melt gear pump. Suitable for extrusion and transportation of polymer melts from low viscosity to extremely high viscosity; Generally installed between the extruder outlet and the die head, used as a melt metering pump; It can also be installed in polymer melt pipelines for use as a booster pump.

The main function of the extrusion granulation melt pump is to provide continuous and stable melt flow, thereby ensuring the smooth progress of extrusion production. In traditional extrusion production, plunger conveying is often used for melt conveying, which has the problems of discontinuous and unstable conveying, which can easily lead to unstable quality of extruded products. The extrusion granulation melt pump adopts a rotating structure, which sucks the melt into the pump through the high-speed rotation of the rotor, pressurizes and accelerates inside the pump, and finally delivers it to the extruder at a stable pressure and flow rate. This conveying method has the characteristics of continuity, stability, and efficiency, which can significantly improve the quality and output of extruded products.

The main characteristics of granulation extrusion melt pump

1. Minimal pressure flow pulsation can achieve linear output of flow, suitable for precision extrusion systems.

2. Adopting different structures and material configurations for different working conditions can better meet the personalized needs of users.

3. It can be applied to high temperature (350 ℃), high pressure (40MPa), and high viscosity (40000 Pass) working conditions.

4. Precision structure, high precision, and long service life.
