This series is mainly composed of gear, shaft, pump body, pump cover, bearing sleeve, shaft end seal, etc; The gear is made of double circular arc sinusoidal profile. Compared with the involute gear, the most outstanding advantage of the gear is that there is no relative sliding of the tooth profile during gear engagement, so the tooth surface is not worn, the operation is stable, there is no liquid trapping, and the noise is low, the service life is long, and the efficiency is high; The pump gets rid of the bondage of traditional design, which makes the gear pump enter a new field in design, production and use.
