NP-WS Sand Dredging Gravel Pump

NP Sand Dredging Gravel Pump Naipu® NP-WS dredging pump is single-stage single-suction cantilever horizontal centrifugal pump with advantages of light weight ,good wear-resistant ,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 .The pump mainly consists of the pump head , gearbox specifically for the dredging pump ,high elastic coupling and supervisor system of the driving device for the dredge. Strongly wear resistant casting alloy iron, whose hardness is not less than 58 HRC, adopted for the casting impeller ,front liner and rear liner of wet parts. Our company can select different kinds of material according to different media to meet the dredging requirement. 1 Ws Dredging Pump is a new type of sludge pump reseached and manufatured by our factory aiming at the dredging and damming of the river and seas. 2. The means is consider to be a treatment of no -pollution to environmental protection, high efficiency and energy-saving  3.Light weight, good wear-resistant, super dredging performance  4.Our Company can select different kinds of material according to different media to meet the dredging requirement.
