submersible pump dredger

Dredger, Cutter Suction Dredger, Sand Washing Machine manufacturer / supplier in China

Technical Parameters

Julong Sand Dredgers:

Various types: mainly cutter suction dredger, bucket chain dredger, jet suction dredger

Dredging depth: maxi. 20m

Dredging capacity: maxi. 5000m3/hr waterflow

Discharge distance: 2000m or more with pump station

Usage: sand dredging, waterway cleaning, reclamation work, mining job, etc.


Submersible dredgers:

Instead of using pump on board, submersible pumps will be used to create better dredging efficiency. The submersible pump has the following advantages.

* Efficiency up to 92%(as measured in practice) resulting in lower fuel consumption at unchanged production

* Reduced and more even wear, resulting in longer lifetime of wear parts

* Highly versatile application due to steep flow head ratio curve

* Better performance as a result of the low net positive suction

* Improved resistance to cavitation

* Limited influence of wear on pump performance.

* Advanced hydraulic model, CAD three-dimensional design, high efficiency, significant energy saving, large deepening, high concentrations dredging, cavitations performance, super suction and over-flow capability, continuously pumping gravel and high mold clay block.

* It can be equipped with diesel engines or be equipped with motor driven directly. It has the advantages of working stability, little vibration, low noise and low hydraulic loss, high efficiency, low fuel consumption and small size, light weight, simple structure, easy maintenance.
