Naipu® WN series dredge pump is a new type of sludge pump researched &manufactured by our company,this series pumps are single-stage single suction cantilever horizontal centrifugal pumps with advantages of light weight, good wear-resistance, super dredging performance,perfectly suited for the dredge on the whole construction,high multiple economy benefits and so on.It throughout meets requirements of the dredge to dredging pumps.
Strongly wear-resistant casting alloy iron,whole hardness is not less than 50HRC adopted for casting,impeller,front liner and rear liner of wet end parts.
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.
