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.
There are two enclosed spaces between two gears, a pump body, and front and rear covers. When the gears rotate, the volume of the space on the side where the gears are disengaged becomes larger, forming a vacuum, and sucking in liquid.
The volume of the space on the gear mesh side changes from large to small, and liquid is squeezed into the pipeline.
The suction cavity and the discharge cavity are separated by the meshing line of the two gears. The pressure at the outlet of the gear pump depends entirely on the resistance at the outlet of the pump.
