Melt pumps in the XPS extruded foam sheet industry

Inquiry info@battemachinery.com Free chat online

Batte melt gear pumps for thermoplastic extrusion processes, such as sheet, plate, pipe and film industries require a special stable extrusion pressure flow system between the outlet and the die head of the metering pump installed in the extruder. This series of melt pump adopts special gear structure and special flow design to ensure stable outlet pressure and flow rate.
