    WN type dredging pump is a new type of mud pump developed by using various advanced computer-aided design software, aiming at the current situation that rivers, lakes and seas in my country are in disrepair, and the dredging and filling work are imminent.

    Features:   

    1. The overall structure is good for marine use. The 200WN-500WN dredging pump adopts a single pump casing, a horizontal single-stage single-suction cantilever structure as a whole, and can provide two structures according to the connection method with the gear box, namely the pump box integrated type or the self-contained bracket type. The 600 WN -10000 WN dredging pump adopts a double pump casing, a horizontal single-stage single-suction cantilever structure, and comes with a bracket. The front disassembly structure is adopted, which is easy to disassemble and assemble and easy to maintain.

    2. Excellent dredging performance, good cavitation performance, strong suction capacity of the pump, large excavation depth, high concentration, wide flow channel of the pump, good over-current performance, the performance curve of the mud pump drops sharply, and the difference of the row spacing The change has good adaptability, and the flow head can be adjusted by changing the speed or diameter of the impeller.

    3. Excellent wear resistance and long life of overcurrent components.

    4. Small hydraulic loss, high efficiency and low power consumption.

    5. The shaft seal is reliable and has no leakage.

    Scope of application:

    Mainly used for dredgers, dredging rivers, mining and conveying blasting slag from metal smelting, etc.
