Melt pump and screen changer

Product Introduction

L series low viscosity melt pump is mainly used in resin, chemical fiber and other industries in low viscosity, low outlet pressure, large flow of material transportation, pressurization, such as polymer solution, glue solution, monomer, oligomer, prepolymer and other materials. Generally installed in the melt pipeline, used as a booster pump; It can also be installed in an electrically-heated extruder system for metering pumps. This series of melt gear pump has better self-priming performance.

Main features of L series melt gear pump

1) Can be applied to high temperature (350℃) conditions can also be adapted to normal temperature conditions;
2) Suitable for low pressure and large flow conveying of low viscosity materials;
3) Good self-priming performance
4) Precise structure, high precision, long life.
