Aiming at the system requirements, to make the gear pump achieve the requirements of high reliability and zero leakage, a special structure gear pump was designed. Using magnetic transmission to make gear pump and motor connect with noncontact, the traditional structure of the shaft seal was canceled,so the input power of the motor was reduced. The dynamic seal was transformed into static seal, and the requirement of zero leakage was achieved.
