Rexroth Gear Pump AZPF-12-011RCB20MB Silvery Colour For Extrusion Line Increase Output

The concept of gear pump is very simple. Its most basic form consists of two gears of the same size in a closely matched housing meshing rotation. The interior of the housing resembles an "8" shape, with two gears installed inside where the outer diameter of the gears and both sides of the housing are closely matched.

The material from the extruder enters the middle of the two gears at the suction inlet, fills this space, moves along the housing with the rotation of the teeth, and finally discharges when the two teeth mesh.

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

External gear pump is the most widely used gear pump, and generally when people refer to gear pumps they mean external gear pumps. The structure mainly consists of driving gear, driven gear, pump body, pump cover and safety valve. The seal space composed of the pump body, pump cover and gear is the working area of the gear pump.

External gear pumps have simple structure, light weight, low cost, reliable operation and wide application range.
