Dredging Pump

Dredging Pump:
Series of dredging pump,which is designed and researched by our company --HISEA is one new type dredging pump, making full use of advanced CAD software, aiming to river, lake and sea situation in China: they haven' t been repaired for many years and now they are in great need to dredge and fill hydraulically.

This series of dredging pump has characteristic features: easy installation, long-life service, high efficiency, reliable bearing lining and good economical efficiency. . . This type of pump can meet requirements of dredging ships completely and each set of dredging pump has passed the inspection issued by CCS.

The Features and Performance of Dredging Pump
The whole construction is suitable for dredging ship.
1. Reliable and simple structure
2. Easy Disassemblyand Installation Convenient Maintenance
D dredging pump is adopted front-disassembly structure in favor of disassemblyand maintenance. Also it is equipped with special disassembly tools for each different parts according to each parts' characters.
The standardtrapezoidal quadruple thread is adopted to connect the impeller and shaft wich not only transmits strong torque but also is easy to disassembly. Meanwhile there is a disassembly
impeller ring in the shaft sleeve in favor of disassembling impeller.

Dredging Performanceis excellent
1. Good NPSH
D dredging pump has good NPSH which ensures the strong suction ability as well as deeper dredge depth and denser dredged mud.
2.Strong Through-put Capability, Wide Application
The wide running passage of impeller of Ddredging pump and the dredging pump' s strong passing capability make sure of the good performance of dredger. While it can deliver the particles or high plastic soil lump persistently and clogging won't happen.
3.The Curve of Performance Decreases Sharply
The capability and head curve of D dredging pump decrease sharply, which makes dredging Pump, is easier to adjust to the change of the distance of piping water.
4.It is realized that D dredging Pump Performance Can Be Changed
At the same flow capability. changing the impeller's rotating speed or changing the impeller diameter can change the head of D dredging pump.

Excellent Anti-wear Performance, Long Service of Wet Parts
Wet parts of this kind of dredging pump -- impeller, liner and front &back liner plate are adapted anti-wear cast iron alloy whose hardness is more than 58HRC, who has both strong antiattack feature and higher resistance wear and resistance abrasion features. The hardness of H31 material that is researched and tested successfully by Delin can research 70HRC.
For fully considered the life-service match between each spare part. the resistant wear parts
have the same replacing period which is good to maintain and reduce the replacing cost.

A little hydraulic loss , High Efficiency, Low power Consumption
Due to adopting advanced hydraulic model, D dredging pump efficiency is very high. Series of D dredging pump working efficiency is higher 2-3 percent than the exported dredging pump working efficiency. Therefore, it can reach lower oil consumption at the same productive quantity.

Reliable shaft sealing without leakage
