Product Description

Dredger Pump

Model: WN(Q) 
Power: 300-5000kw
Size: 200mm to 1200mm
Max Capacity: 16000 m3/h
Max Head: 78m
1.Cylindrical structure of bearing assembly: convenient to adjust the space between impeller and front liner and can be removed completely;
2. Interchangeable anti-abrasive wet parts made of high-chrome alloys;
3. The discharge branch can be oriented to any eight positions at the interval of 45 degrees;

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 material:
Cr27,Cr28,etc



Material advantage:
High chromium alloy, more wear-resistant!
Self-casting, self-processing, each material has a spectral analysis report.
Ensure quality while truly saving costs for you!

 

Real factory!  There is no middleman to profit from the price difference!


 

Main Parts:
Impeller, Casing, Strainer, Discharge pipe, Frame Plate Liner Insert,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.
