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.

Selection of polymer melt gear pump
The flow rate of the extruder melt metering pump is related to the working speed, material viscosity, and working pressure. Please consult the manufacturer for specific selection. The selection of melt metering pumps requires the following parameters:
1. Flow rate or output;
2. Material name;
3. Material viscosity;
4. Corrosiveness/toxicity of materials;
5. Inlet and outlet pressure (pressure difference);
6. Operating temperature.
