Due to the advanced nature of the hydraulic model, the efficiency level of this pump is high, 2-3% higher than that of other sand dredge pump. Outstanding qualities of this sand dredge pump include a simple and strong overall structure, long service life, high efficiency, a reliable shaft seal, and significant cost savings. By changing pump speed or impeller diameter, the flow capacity and pump head can be adjusted. It also has a large flow channel and good flow capacity. Through an optimized design, the WN(Q) suction dredge pump has excellent performance, high suction capability, and the ability to dig deeper. These are made of strong wear-resistant alloy cast iron and hardness of no less than 58HRC.
