Main Structure and Function of Polymer melt pump extrusion

The combination of polymer melt pump and screw extruder can improve extrusion yield and quality, reduce energy consumption, and play a role that cannot be replaced by other processing methods in precision extrusion molding. At present, the materials it can process almost cover most polymer materials, such as PE, PC, PP, PVC, PET, polysulfone, polyester, fluoropolymers, thermoplastic elastomers, and rubber.

Polymer melt gear pump structure

A complete set of polymer melt gear pumps provided by Zhengzhou BATTE includes motors, reducers, couplings, and pump heads. The pump head is composed of the pump casing, front and rear side covers, gear shafts, sliding bearings, and shaft seals.

Melt pump extrusion function

The melt pump extrusion is mainly used for melt transportation, pressurization, and metering, and has the characteristics of compact structure, reliable operation, low energy consumption, small volume, and low shear effect on the melt. The melt gear pump transports polymer melt, which needs to work continuously at high temperatures below 350C and high pressures of around 30MPa; The material of the pump should be temperature resistant, wear-resistant, corrosion-resistant, and have sufficient strength and dimensional stability.
