Gear Pump

Gear Pump:

The gear pump is a rotary pump that relies on the change and movement of the working volume formed between the pump cylinder and the meshing gear to transport liquid or pressurize it. According to the different meshing forms of gear pumps, there are two types of gear pumps: external gearing and internal gearing.

The internal gear pump adopts the principle of internal gear meshing. The pitch circle of the internal and external gears is close to one side, and the other side is separated by the "crescent plate" on the pump cover.
The driving internal gear on the main shaft drives the external gear to rotate in the same direction. At the inlet, the gears are separated from each other and form a negative pressure to suck in liquid. At the outlet, the gears are continuously embedded and meshed to squeeze out the liquid.

Internal gear pumps are suitable for transporting Newtonian or non-Newtonian liquids in industries such as petroleum, chemical, paint, dyes, food, grease, and medicine. The type of conveying liquid can be volatile liquid, to viscous, or even semi-solid liquid.

As a trusted distributor in China for years, A&S Hydraulic can provide a broad series of gear pumps, such as rotary gear pump and internal gear pump at the most competitive price.
