Dredge Pump Performance Parameter

Dredge pump Feature

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

 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.

Excellent ant-wear performance,long service of wet parts

A little hydraulic loss,high efficiency,low consumption

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

Drive type:Generally use belt driven or Gear transmission

Materials of dredge pump:

Material of wet parts is high wear resistant high chrome alloy.

Considering the maintenance,wear resistant parts are nearly of the same wear life to reduce maintenance&interchange costs.

High chrome A05, A31, A33, A49 etc.

High chrome alloy-- WHITE cast iron:

A05--used for higher wear condition with PH between 5--12

A33-- Transport oxygenated slurry with PH≥1, such as phosetcphor-plaster, nitric acid, vitriol, phosphate,etc.

A49--Used for lower PH working condition, especially for glue gas; 

also used for low-sour condition and desulfuration installation with PH not less than 4.Material of wet parts is high
