Upgraded HDN series gear metering pump heating gear pump

The HDN series heated gear pump is an upgraded version of the D-type sleeve-type heated medium pump. This design allows for simultaneous heating of the sealed cavity. The heating medium can be steam, hot water, heat transfer oil, or other media, and it can precisely deliver various chemical media requiring clean heating, such as resins, pharmaceuticals, asphalt, various wax products, and high-viscosity fluids like syrups.

HDN series features

The HDN series heating gear pump is a polished version of the D-type sleeve structure for heating medium. Its simple appearance ensures the transport of high-viscosity media during heating. This structure allows for simultaneous heating of the sealed chamber. The heating medium can be steam, hot water, thermal oil, or other media, and can transport a variety of chemical media requiring clean heating, such as resins, pharmaceuticals, asphalt, various wax products, and high-viscosity fluids such as syrups.
