The hydraulic design of WN dredge pump adopt CFD to carry on the flow field simulation, the pump efficiency is high, simultaneously avoids in the flow channel the excessively quick change to the overflow partial attrition, reduce the spare parts the consumption. YN Type pump wet-end part uses the high strength antifriction metal materials (KmTBCr27), degree of hardness is not lower than 58HRC, has very strong bears the impact ability and good abrasion. The good NPSH performance of WN type pump ensures the strong suction ability as well as deeper dredging depth and denser dredging concentration. Also it is equipped with special disassembly tools for each different part according to each parts features. YN type pump adopts front-disassembly structure in favor of easy disassembly and maintenance. The pump can be directly matched with either motor or diesel engine. The pump can persistently discharge gravel, high plastic soil lump,etc. Structure suitable for dredging ship: Strong through-put. Specification: Capacity/Flow: 1800-25000m3/h Head / Lift: 20-78m Speed: 180-550 rpm Medium density: PH of Medium: 5-12 Caliber: 300mm -1000mm Usages: YN series dredge pump is designed for the dredging and damming for lake, river and other construction Suction Hopper Dredging Constructional Material Sand gravel processing Barge Loading Sand Reclamation Rivers dredging Features: 1. Can meet all the requirements from the dredge. Large dredging depth, high density of dredging mud, good NPSH and strong suction lift ability. YN series Dredge Pumps are horizontal cantilevered single stage, single suction pump.
