The gear pump is driven by an independent motor, which can effectively block upstream pressure pulsation and flow fluctuations. The pressure pulsation at the outlet of the gear pump can be controlled within 1%. Using a gear pump on the extrusion production line can increase the flow output speed and reduce the shear and residence time of materials in the extruder.

External gear pump is the most widely used type of gear pump, and generally refers to external gear pump. Its structure is shown in Figure 1, mainly composed of driving gear, driven gear, pump body, pump cover, and safety valve. The sealing space composed of the pump body, pump cover, and gears is the working chamber of the gear pump. The axles of the two gears are respectively installed in the bearing holes on the two pump covers, and the driving gear shaft extends out of the pump body and is driven to rotate by an electric motor. The external gear pump has a simple structure, light weight, low cost, reliable operation, and a wide range of appliions.
