Product Description

Description:
WN 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.

Typical Application:
dredging and hydraulic fill

Features:
Abrasion-resistance,corrosion-resistance; large capacity; wide flow channel; light weight; good performance of NPSH; easy maintenance; anti-clogging.
Special clamping device of the jointing for pump body and pump cover enables the pump discharge point to any direction.
The wet parts , including impeller, frame plate, throatbush, frame plate liner insert, all adopt anti-corrosive alloy cast iron or steel.
The pump consists of pump head, seal assembly, bearing assembly and frame. The bearing assembly is lubricated by grease.
The pump can be driven by V-belt, coupling directly or by reducer.
Packing seal, expeller seal and mechanical seal are all available for the pump.

1.The whole construction is suitable for dredging ship
1)Reliable and simple structure(200WN~500WN type is single casing pump,600WN~1000WN is double casing pump)
2)Easy disassembly and installation,convenient maintenance

2. Dredging performance is excellent,

1)good NPSH,strong through-put capability
2) The curve of performance decrease sharply,to make the pump more adaptive in the change of discharge distance.
3) Pump performance can be in a variety of change.

3. Excellent ant-wear performance,long service of wet parts

4. A little hydraulic loss,high efficiency,low consumption

5. Reliable shaft sealing without leakage

200WN~500WN type usually adopts gland sealing or mechanical sealing or mechanical and packing compound sealing;600WN~1000WN adopts rubber sealing device

6. Drive type:Generally use belt driven or Gear transmission
