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. The overflow parts of this suction dredge pump include the impeller, sheath, and front and rear shields (wear-resistant liners). This device consists of 3 L-shaped seal rings and a shaft sleeve with special threads. The shaft seal of the 600WN-1000WN dredging pump uses a spiral sleeve L-shaped rubber seal device. The 200WN-500WN dredging pump shaft adopts a mechanical seal, packing seal, or mechanical seal plus packing compound seal.

It is composed of a pump head, reduction gearbox, highly elastic coupling, and a marine transmission monitoring system. This model is a single-stage, single-suction, horizontal centrifugal pump. Adopting advanced technology, this pump is widely used in cutter head dredgers or other dredging equipment.
