WN(Q) series is a new dredge pump developed by our company adopting advanced CAD technology, the dredge pump is widely used in cutter head dredger or other dredging equipments. The pump is horizontal single-stage single-suction cantilever structure. The double casing structure can guarantee long-term safe and reliable running.
Main Parts:
Impeller, Casing, Bearing assembly, Frame Plate Liner Insert，etc
Main material:
Cr27,Cr28, etc.
Advantage:
1. The WN type is used in the cabin, and the WNQ type is used underwater, which meets the mud requirements of different hull structures and has wide applicability;
2. Through optimized design, the WN(Q) dredging pump has good performance, strong suction capacity of mud, large digging depth and high concentration;
3. Excellent wear resistance, long service life of flow parts;
4. Using CFD for flow field simulation, the dredging pump has high efficiency and avoids internal flow in the flow channel.
