What are the differences of high-temperature melt-pumps?

The pump body of high-temperature melt pumps adopts integral hardening technology and is made of high-temperature alloy steel materials with high wear resistance and corrosion resistance. Compared to ordinary extrusion pumps, they are more suitable for high-temperature and high-pressure working conditions, meeting the performance requirements of some users. High-temperature melt pumps are based on standard series melt pumps, with enhanced design parameters for the pump body, such as high torque, low shear requirements, and high corrosion resistance requirements (including fluorine-containing products).

Optimized designs have been implemented for the self-lubrication system, inlet and outlet flow channels, and gear structure of the pump body in high-temperature melt gear pumps. These designs reduce the residence time of materials within the pump body, prevent dead zones in the pump gears, and make them more suitable for extruding products with high smoothness and transparency requirements, such as PC, PMMA, and PVC, as well as heat-sensitive materials.
