WN Series dredge pumps are new type of dredge pump, aiming to river, lake and sea situation with lower maintenance cost. WN series dredge pump is a single-stage single suction cantilever horizontal centrifugal pump with advantages of light weight, good wear-resistance, super dredging performance, perfectly suitable for the dredge on the whole construction, high multiple economy benefits, etc.

Suitable structure for dredging ship

200WN, 250WN, 300WN, 350WN, 400WN, 450WN and 500WN are single-casing, single-stage, single-suction, cantilever and horizontal dredge pumps . According to the connection with the gear box, there are two structures can be offered: self-carrying bracket and pump-box assembly. The lubrication for the bracket is grease or thin oil.
600WN, 700WN, 800WN, 850WN, 900WN and 1000WN are double-casing, single-stage, single suction, cantilever and horizontal dredge pumps.They are self-carrying bracket with thin oil lubricating.

Easy to Disassembly and Installation, Convenient Maintenance

WN type dredge pump adopts front-disassembly structure in favor of easy disassembly and maintenance. Also it is equipped with special disassembly tools for each different part according to each part's features.The standard trapezoidal quadruple thread is adopted to connect the impeller and shaft, which not only transmits strong torque but also is easy to disassembly.

Good NPSH Performance

The good NPSH performance of WN type dredge pump ensures the strong suction ability as well as deeper dredging depth and denser dredging concentration.

Good Wear-resistant Performance, Long Service Life of Wet Parts

The dredge pump impeller, liner and front & back liner plate are adapted anti-wear cast iron alloy whose hardness is more than 58HRC, which has both strong anti-attack feature and higher resistance wear and resistance abrasion features. The hardness of BA31 material that is researched and tested successfully by us can research 70HRC.

Reliable Shaft Sealing Without Leakage

200WN, 250WN, 300WN, 350WN, 400WN, 450WN and 500WN are used the mechanical sealing or stuffing sealing or mechanical-stuffing compound sealing.
600WN, 700WN, 800WN, 850WN, 900WN and 1000WN dredging pumps are adopted spiral sleeve L (shape) rubber sealing device that consists of three L sealing ring and one special thread shaft sleeve.
