Special metering pump for thermoplastic extruder

The ZB-B series extruder dedicated metering pump is a universal metering pump used in electric heating extrusion systems. Suitable for extrusion and transportation of polymer melts from low viscosity to extremely high viscosity; Generally installed between the outlet of the extruder and the die head, used as a thermoplastic melt pump; It can also be installed in polymer melt pipelines for use as a booster pump. It is widely used in various extrusion industries, such as sheet, sheet, pipe, film, granulation, wire drawing, cable, co extrusion, mixing, precision extrusion, etc.
