Technical features and performance:
1.The whole construction is suitable for dredging ship.
a.Reliable and simple structure
The 400WN dredging pump is designed into double suctions single-stage, single -suction cantilever horizontal structure with bracket wich is lubricated by forced diluted lubricant. The safety and reliability of double pump casing make the liner used up until it is nearly broken. Even if the liner broken , water can’t flow into pump casing.
b.Easy Disassembly and Installation Convenient Maintenance.
2. Dredging Performance is excellent.
a.Good NPSH
b.Strong Through-put Capability, Wide Application.
c.The Curve of Performance Decreases Sharply.
3.Excellent Anti-wear Performance, Long Service of Wet Parts.
4.A little hydraulic loss, High Efficiency, Low power consumption.
5.Reliable shaft sealing without leakage.
The 400WN dredging pump adopts spiral sleeve L shape rubber sealing device that consists of three L sealing ring and one special thread bearing shaft sleeve.
Dredge pump types:
1.Single-walled dredge pump.
2.Double-walled dredge pump.
3.Underwater Dredge Pumps.
