Gear pumps are a common type of positive displacement pump used to transport liquids or lubricants. It consists of two or more meshing gears, and the pumping effect is produced by the meshing motion between them.

Here's how a gear pump works: When the drive shaft rotates, the gears rotate with it. The meshing between two or more gears forms a series of sealed working chambers. The liquid enters the working chamber through the suction port. As the gears rotate, the working chamber gradually decreases and the liquid is forced to be squeezed from the suction port to the pressure port. In this way, liquid pumping is achieved.

Features of gear pumps include:

Simple and compact structure, easy to manufacture and maintain.

Small size and light weight, suitable for applications where space is limited.

The conveying flow is stable and the flow pulsation is small.

Able to pump high viscosity liquids and high pressure liquids.

Smooth operation and low noise.

Suitable for transporting low viscosity media such as lubricating oil.
