Insulation gear pumps are designed for the transportation of media that become thick, solidify, or crystallize at room temperature but remain easily flowing at a controlled temperature, such as asphalt, paraffin, rosin, heavy oil, resin, and similar liquids, with temperatures not exceeding 300°C.
The pump body features a circulating jacket, which can be used to heat, insulate, and cool the transported liquid and the pump with media such as thermal oil, steam, hot water, and cold water. After shutdown, the medium inside the pump remains melted, allowing high-viscosity media to fill the pump chamber, effectively performing the function of transporting high-viscosity media.

Advantages:

Distinctive design, featuring hollowed cores at all major overcurrent sections.

Sealed in various types, catering to different requirements and material characteristics, we offer both filling seal and mechanical seal options. Additionally, sealing cooling jackets or insulation sleeves can be installed based on the on-site material characteristics.

A variety of drive motors are available, including reduction gears, variable speed motors, or belt pulleys, to accommodate the characteristics of different materials.

Coupling configurations are diverse, utilizing elastic claw couplings, elastic pin couplings, and diaphragm couplings (for high temperatures) based on site temperature and customer requirements.
