Wzj model for the single-stage, single-suction, cantilevered horizontal centrifugal slurry pump, this series pump adopt international advanced solid-liquid two-phase flow theory, according to the principle of minimum loss design. The over-current components geometry conforms to the flow of the medium, to reduce the eddy current and impact, so as to reduce the flow components of wear, improved the hydraulic efficiency, reduce the running noise and vibration;
