The gear and shaft of the pump are integrated and adopt a whole body quenching process, which can achieve a longer working life. The "D" type bearing combines a forced lubriion mechanism, allowing the polymer to pass through the bearing surface and return to the inlet side of the pump to ensure effective lubriion of the rotating shaft. This characteristic reduces the possibility of polymer retention and degradation. The precision machined pump body can accurately match the "D" type bearing with the gear shaft, ensuring that the gear shaft is not eccentric and preventing gear wear. The Parkool sealing structure and polytetrafluoro lip seal together form a water-cooled seal. This type of seal does not actually contact the surface of the shaft, and its sealing principle is to cool the polymer to a semi molten state to form a self sealing. Rheoseal seals can also be used, which have reverse spiral grooves machined on the inner surface of the shaft seal, allowing the polymer to be back pressed back into the inlet. For ease of installation, the manufacturer has designed a ring bolt installation surface to match the flange installation of other equipment, making the manufacturing of cylindrical flanges easier.
