摘要： A liquid gear pump includes a gear pump assembly and an electric motor with an motor shaft. The gear pump assembly includes a pump housing which defines a pump chamber, an inlet and an outlet which are in fluid communication with the pump chamber, and a driving gear and an idle gear which are received in the pump chamber. The driving gear is driven by the motor shaft. The idle gear is supported on an idle shaft and engaged with the driving gear. The driving gear and the idle gear are made of a material with a main component of PPS.
