Structural Features Of Gear Pumps

(1) Simple structure and cheap price;
(2) Low work requirements and wide application;
(3) The intercogged grooves of the end cover and the gear form many fixed sealing working chambers, which can only be used as quantitative pumps.

The gear adopts the new technology of the international advanced level in the nineties - double arc sinusoidal tooth type arc. Compared with involute gears, the most prominent advantage is that there is no relative sliding of the tooth profile during the gear meshing process, so there is no wear on the tooth surface, balanced operation, no trapped liquid phenomenon, low noise, long life and high efficiency. The pump gets rid of the shackles of traditional design, making gear pumps enter a new field in design, production and use.

The pump is equipped with a differential pressure safety valve as overload protection, and the full return pressure of the safety 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 safety valve cannot be used as a pressure reducing valve for a long time, and the pressure reducing valve can be installed separately when needed.
The pump shaft end seal is designed in two forms, one is a mechanical seal and the other is a packing seal, which can be determined according to the specific use and user requirements.
