WN series high-efficiency dredge pump is a new single-stage, single suction, cantilever horizontal centrifugal dredge pump, especially suitable for dredging, filling and other operations in Rivers and Lakes, which fully meets the requirements of dredgers for pumps. The wet parts are made of 27% wear-resistant high chrome alloy, with high head, large flow, high efficiency, good NPSH and other advantages; Sustainable output of gravel, mud, etc. It is applicable to the fields of river dredging, old sand reclamation, and explosive sludge treatment in metal smelting.

1. Cantilevered, horizontal, centrifugal, one stage, single casing pump;

2. High head, large capacity, high efficiency, good NPSH performance;

3. Long bearing life, the bearing assembly with large diameter shaft and short overhang;

4. Wear-resistant wet parts, the wet parts are made of Ni hard and high chromium abrasion resistant alloys. (more than 27% Chrome alloy);

5. The shaft seals can be gland seal or Lip seal;

6. Front-disassembly design for easy disassembly& maintenance; According to the feature of each part, equip the specificity disassembly tools for disassembly.

7. The standard four-head trapezoidal thread is adopted to connect between the impeller and shaft. It both transfers strong torque and easy dis&assembly. Set an impeller release collar between the shaft and the labyrinth to aid disassemble the impeller conveniently.

WSIR high efficiency horizontal dredge pump are designed for heavy duty applications such as mining, power sector, dredging river, and tailings as well as specialty applications, which are used for continuous pumping of high abrasive, high density sand and gravels.
