KW series dredging pump is single stage single suction horizontal cantilevered centrifugal pump. Our company designs and researches this new type dredging pump by making full use of advanced CAD software, aiming to dredging river, lake and sea which is in great need to dredge in China. The use of this pump has remarkable comprehensive economic benefits and can meet dredging ship's requirements completely.
It is used for dredging and hydraulic fill.
● The whole construction is suitable for dredging ship.
①Reliable and simple structure (200KW~500KW type is single casing pump, 600KW~1000KW is double casing pump)
②Easy disassembly and installation, convenient maintenance
● Dredging performance is excellent
①good NPSH, strong through-put capability
②The curve of performance decrease sharply, to make the pump more adaptive in the change of discharge distance.
③Pump performance can be in a variety of change.
● Excellent ant-wear performance,long service of wet parts
● A little hydraulic loss,high efficiency,low consumption
● Reliable shaft sealing without leakage
200KW~500KW type usually adopts gland sealing or mechanical sealing or mechanical and packing compound sealing;600KWN~1000KWN adopts rubber sealing device
● Drive type:Generally use belt driven or Gear transmission
