    Description

    WN450 Sand Dredge Pump is singe stage single suction horizontal cantilevered centrifugal dredging pump. Tobee designs and researches this new type dredging pump by making full use of advanced CAD software, aiming to dredging river, lake and seal which is in great need to dredge in the world. The use of this dredge pump has remarkable comprehensive economic benefits and can meet dredging ship's requirements completely.


    Design Features:

    √ Structure suitable for dredgers:
    The structure of WN450 type dredge pumps are single-casing, single-stage, single-suction, cantilever and horizontal. According to the connection with the gear box, two structures can be offered: self-carrying bracket and pump-box assembly. The lubrication for the bracket is grease or thin oil.
       
    √ Easy to Disassembly and Installation, Convenient Maintenance:
    WN450 dredge pump adopts front-disassembly structure in favor of easy disassembly and maintenance. Also it is equipped with special disassembly tools for each different part according to each part’s features. The standard trapezoidal quadruple thread is adopted to connect the impeller and shaft, which not only transmits strong torque but also is easy to disassembly.
     
    √ Good Performance on NPSH:
    The good NPSH performance of WN450 dredge pump ensures the strong suction ability as well as deeper dredging depth and denser dredging concentration.

    Good Wear-resistant Performance, Long Service Time of Wet Parts:
    Wear parts of this kind of dredging pump-impeller, liner and front & back liner plate are adapted anti-wear cast iron alloy whose hardness is more than 58HRC, who has both strong anti-attack feature and higher resistance wear and resistance abrasion features. The hardness of TA31 material that is researched and tested successfully by us can research 70HRC.

    √ Reliable Shaft Sealing Without Leakage:
    The shaft of WN450 dredging pump uses the mechanical sealing or stuffing sealing or mechanical-stuffing compound sealing.
