High efficiency 14' jet suction dredger for sale including pump and engine

Product description

A suction sand pumping vessel is an engineering vessel or equipment that uses the negative pressure (vacuum) generated

by high-pressure water jets to extract underwater sand, silt or gravel. It is an important way of hydraulic sand pumping (or

dredging),especially suitable for loose sand media.

product parameters

The above technical parameters are for reference only,specific device configuration depends on the conditions of each

project,customer and technical requirements.

Core Working Principle: "Jeting" + "Suction"

"Jeting" - Loosening mud and sand with high-pressure water jets:
The vessel is equipped with a high-powered high-pressure water pump.
The pump draws clean water from the operating area, pressurizes it, and delivers it underwater through a high-pressure water pipe.
A specially designed nozzle/nozzle is installed at the end of the high-pressure water pipe, which directs the high-pressure water onto

the target sand layer.

Function: The high-pressure water jet has a powerful impact force that can:
Disperse loose sand particles.
Cut and liquefy compacted mud and sand layers, making them soft and fluid.
Creating a sand-water mixture (slurry): Thoroughly mixing sand and water reduces the slurry's viscosity, making it easier to pump.

"Suction" - Suctioning the slurry with a centrifugal pump:

A sand suction head/sand suction pipe inlet is located near the high-pressure nozzle (usually directly above or to the side and rear).
The vessel is equipped with a centrifugal sand pump (or slurry pump).
When operating, the sand pump generates a powerful vacuum suction force. The sand-water mixture (slurry) dispersed and liquefied

by the high-pressure water jet is forcefully drawn into the sand suction pipe through the suction head under the negative pressure

generated by the sand pump.The sucked-in slurry is then transported via pipelines to its destination (e.g.,a transport vessel, a shoreside

storage yard, a self-contained simple cabin/floating tank, or directly used for blow-filling).

Application
Dredging engineering:

Excavation, widening, deepening and maintenance of waterways, ports and canals.

Dredging of river channels, flood prevention and disaster reduction, improvement of navigation conditions and water quality.

Dredging of reservoirs and lakes, restoration of storage capacity and improvement of water quality.

Excavation of foundations for water conservancy projects.

Land reclamation: Extracting sand and gravel from the seabed or offshore for the construction of artificial islands and expansion of

land area (ports, airports, urban land).

Mining (sand and gravel aggregates): Mining river sand, sea sand, gravel, etc. as building materials.

Environmental governance:

Dredging of polluted sediments (removal of polluted sediments).

Wetland restoration.

Environmental dredging (using environmentally friendly suction boats).

Dig trenches before laying submarine pipelines/cables.

Blowing and filling engineering: Blowing and filling dredged or mined sediment into designated areas (such as strengthening dams

and forming land).
