WN type dredging pump
Structural form:
WN type dredging pump is a single-stage single-suction, horizontal centrifugal pump.
200WN-500WN dredging pump adopts single pump casing structure
500WN-1000WN dredging pump adopts double pump casing structure.
Slurry conveying:
Because the impeller of WN type dredging pump flows to a wide range and has strong passing ability, it can convey the slurry containing large particles and strong abrasiveness, and also the gravel or high plastic clay continuously without clogging, especially suitable for dredging sand and damming in rivers and oceans.
Installation and application:
The export is mainly upward, and the export direction can also be adjusted according to the specific needs of users.

Model Selection Chart:
WN Dredge Pumps are single-stage single suction cantilever horizontal centrifugal pumps with advantages of light weight, good wear-resistan, super dredging performance, WN dredging pumps impeller passage is very wide, It can continuously transport gravels or high plastic clay and not happens jam, Especially for dredging sands and damming of the river and seas.
WN Series Dredge Pumps can be also integrated with the gearbox, That mean the pump and gear box share one common shaft. So It dosen't need the pump bearing aseembly and frame, In this way, Not only save space, but also reduce cost and breakdown ratio, Let the dredge pump give play to maximum effectiveness.
