WN /WNQ series dredging pump is a single state single suction cantilever horizontal type it is divided into two kinds of structures according to the size of pressure discharging single and double pump casing.
200 ~ 500 WN uses the single shell structure 600 ~ 1000 WN uses the double pump housing structure. The double pump housing design may guarantee the long term security reliable movement. 600 ~ 1000 WNQ uses the single pump housing structure. It may use the grease lubrication or the oil lubrication withe the base.
