Technical Features
The construction is suitable for dredging ship
1. Reliable and simple structure
The whole construction of D1200/1000 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.
2. Easy Disassemblyand Installation Convenient Maintenance

Dredging Performance is excellent
1. Good NPSH
2.Strong Through-put Capability, Wide Application
3.The Curve of Performance Decreases Sharply
4.It is realized that D dredging Pump Performance Can Be Changed

Excellent Anti-wear Performance, Long Service of Wet Parts

A little hydraulic loss , High Efficiency, Low power Consumption

Reliable shaft sealing without leakage

The shaft of D1200/1000 dredging pump adopts spiral sleeve L shape rubber sealing device that consists of three L sealing ring and one special thread bearing shaft sleeve.
