The filter press feed pump is widely used in the feeding of the filter press in the petroleum, chemical, starch pharmaceutical, pesticide, dye, paint, leather, papermaking, food and other industries. The filter press feed pump adopts a semi-open impeller, with wide flow channel and good passability, no blockage when conveying the slurry containing particles, and the particles will not be stuck between the impeller and the pump body and the pump cover, so as to make up for the effect that the general centrifugal pump can not achieve. The filter press feed pump has a simple structure and easy maintenance, and its unique structural design can be completed without disassembling the pipeline when repairing and replacing impellers, seals, bearings and other wearing parts. The filter press feed pump adopts a unique hydraulic design and impeller installation method, which ensures that its performance curve is steeper than that of the general impurity pump, which is very suitable for the change of resistance when the filter press is fed to achieve the purpose of large flow, low pressure feeding and small flow and high pressure filtration.Its special hydraulic properties coincide with the gradual process of the filter press from cavity to filling and then to drying. At the beginning of feeding, the motor overload caused by excessive flow is not controlled by the valve, and the low pressure will not have an impact on the filter plate frame, which reduces the damage of the filter cloth on the filter plate frame, and will not impact the filter plate to cause vibration. Especially in the later pressing period, the unique impeller installation method and the role of the auxiliary impeller of the same pump under high pressure ensure that the shaft seal is basically leak-free.
