Gear Pump Size Calculator 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 deliver or pressurize the liquid. Two closed spaces are composed of two gears, the pump body and the front and rear covers. When the gears rotate, the volume of the space on the side where the gears are disengaged increases from small to large, forming a vacuum to suck the liquid, and the volume of the space on the side where the gears mesh changes from large to large. Small, and the liquid is squeezed into the pipeline. The suction chamber and the discharge chamber are separated by the meshing line of two gears. The pressure at the outlet of the gear pump depends entirely on the resistance at the outlet of the pump.
