Feeding pump of pressure filter in the half open impeller flow channel width, through sex good, no blockage when deliver a slurry of particles, particles will not stuck in the impeller and the pump body, pump cover, to make up for the general centrifugal pump cannot reach the effect. Feeding pump of pressure filter into the simple structure, easy maintenance, unique structure design, the maintenance, replacement of the impeller, seal the wearing parts such as bearings, can be done without having to remove the pipe.

Feeding pump of pressure filter into the distinctive impeller hydraulic design and installation, to ensure its performance curve steeper than a general impurity pump, very suitable for filter press in should the change of the resistance to achieve large flow, low pressure feed with small flow, high pressure filter. The special hydraulic performance precisely match filter press by the cavity to fill and drain of gradual process. Early feeding without valve control motor overload and low pressure caused by heavy traffic will have impact on the filter plate frame, reduces the filter plate frame filter cloth on the damage, also won't impact vibration filter plate, filter later small flow pressure is not easy to suppress pump. Especially in late stage with pump under the pressure of its unique installation and vice impeller impeller, guarantees to place the basic shaft seal to leak.
