Application, characteristics and parameters of plastic melt metering gear pump

The plastic melt metering gear pump is mainly suitable for the extrusion and transportation of medium and high viscosity polymer melts. It is generally installed between the outlet of the extruder and the die head and serves as a melt pump for extruder.

Characteristics of Plastic extrusion melt pump

1、Optimized melt runner design: eliminate dead space in the runner, reduce the polymer residue to the minimum, and improve the quality of products.

2、Improved gear parameter design: more accurate rotary displacement design, so that the output pressure is more stable, adapted to the precision extrusion working conditions.

3、Applicable to a wide range of viscosity: using different sealing methods, can be applied from low viscosity to very high viscosity working conditions.

4, a variety of installation methods: to meet the user's individual needs.

5、High precision manufacturing and excellent heat treatment: more precise and durable.

melt pump for plastic extrusion

It is recommended to use universal coupling to connect the reducer and plastic melt metering gear pump to eliminate the effect of thermal deformation; the melt pump belongs to the volumetric forced transfer pump, which can be adjusted by adjusting the speed of the pump to regulate the output flow rate of the pump, and it is recommended to use the frequency conversion speed control method, which can realize the near-linear flow rate output of the gear pump.
