Product Details

450WN Dredging Pump • Product Introduction 450WN is 450mm size single shell dredging pump.The pump is marine dredging pump for dredging of river and sea.It is single-stage, single-suction, cantilever, horizontal centrifugal pump.The flow passage of the impeller is wide through the capacity, so it is difficult to block for pumping sand gravel or high plastic clay. It has super strong excavation and suction ability. This pump is simple and reliable in structure, easy to disassemble and maintain, and adopts high chromium wear-resistant alloy material,which has a long trouble-free life. 450WN is suitable for dredging and filling operations of cutter-suction dredger and trailing suction dredger. It is also used for river sand mining and mining vessels. • Product Feature 1.The structure is simple and reliable. The pump adopts single pump casing structure. According to the connecting way of gear box can provide two kinds of typical structures, one is connected with own bearing bracket, the other is combined with reduction gear box. The lubrication of pump with bearing bracket is grease lubrication or thin oil lubrication. 2. Easy to assemble and disassemble and easy to maintain. The front dismantling structure is adopted, and special disassembly tools are equipped to facilitate disassembly and assembly. 3.The performance of dredging is excellent. The flow and head curve of the pump are steep, the suction ability is strong, the ability of passing the pump is good, the change of the distance is more applicable, and the depth of digging and the higher transportation concentration can be reached. 4.Good wear resistance and long life of flow parts. The impeller, volute liner, throat bushing and rear plate liner (wearable liner) are made of strong wear resistant alloy cast iron whose hardness is not less than 58HRC.It has not only impact on resistance but also high anti-abrasi
