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.
