WN series dredging pump is single stage single suction horizontal cantilevered centrifugal pump. Our company designs and researches this new type dredging pump by making full use of advanced CAD software, aiming to dredging river, lake and sea which is in great need to dredge in China.The use of this pump has remarkable comprehensive economic benefits and can meet dredging ship's requirements completely
Type Application
it is used for dredging and hydraulic fill

[2] Features
    1.The whole construction is suitable for dredging ship
       1)Reliable and simple structure(200WN~500WN type is single casing pump,600WN~1000WN is double casing pump)
       2)Easy disassembly and installation,convenient maintenance
    2.Dredging performance is excellent,
       1)good NPSH,strong through-put capability
       2)The curve of performance decrease sharply,to make the pump more adaptive in the change of discharge distance.
       3)Pump performance can be in a variety of change.
    3. Excellent ant-wear performance,long service of wet parts
    4. A little hydraulic loss,high efficiency,low consumption
    5. Reliable shaft sealing without leakage
