The gear pump is manufactured with higher precision to improve the performance of the external contact gear pump, with small pulsation and good volumetric characteristics. These pumps were originally developed for pumping and metering polymers to spinnerets in chemical fiber production and have found widespread use in many other applications. A gear pump is a rotary pump that relies on the change and movement of the working volume between the pump cylinder and the meshing gear to transport liquid or pressurize it. 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 gear disengagement side increases from small to large, forming a vacuum, which sucks the liquid in, and the volume of the space on the gear meshing side changes from large to large. small, and squeeze the liquid into the pipeline. The suction chamber and the discharge chamber are separated by the meshing line of two gears. The pressure at the discharge port of the gear pump depends entirely on the resistance at the pump outlet.
