The gear adopts a new technology with the advanced level of 90 years-double arc sine curve tooth profile arc The gear pumpadopts a new technology with 90 years of advanced level-double arc sinusoidal tooth profile arc. Compared with involute gears, its outstanding advantage is that the tooth profile surface does not slide relatively during the gear meshing process, so the tooth surface has no wear, running balance, no liquid trapping, low noise, long life and high efficiency. The pump gets rid of the shackles of traditional design, making the gear pump enter a new field in design, production and use. The pump is equipped with a differential pressure valve as overload protection, and the total return pressure of the valve is 1.5 times the rated discharge pressure of the pump. It can also be adjusted according to actual needs within the allowable discharge pressure range. However, this valve cannot be used as a pressure reducing valve for long-term operation, and can be installed on the pipeline when necessary. The pump shaft end seal is designed in two forms, one is a mechanical seal, the other is a packing seal, which can be determined according to the specific use conditions and user requirements.
