18 inch(2000 cbm/h) Jet Suction Sand Dredger /Dredging Ship
1.Jet Suction Dredger Product Description
A jet suction dredger is a high-efficiency dredging and sand extraction ship that integrates scouring and suction functions. It operates through a coordinated "jet-and-suction" process. The high-pressure water pump generates a water flow, which impacts the underwater sediment through a water gun, suspending it. The sand suction pump then transports the resulting mixture of mud and water via suction pipes and pipelines to a designated location. This jet suction sand dredger is widely used in the terrain which the sand layer is relatively loose and not compacted.
In order to suggest you one fit model of jet suction sand dredger/dredging ship,would you please kindly take some time to reply below questions: 1.How many cubic meter per hour for the clear water flow? 2. How many meters for the suction depth of the jet suction sand dredger? 3. How many meters for the discharge distance of the jet suction sand dredging ship? 4. For the engine brand of the jet suction sand dredging boat, would you prefer weichai,cummins or Japan Mitsubishi Brand?

4.Jet Suction Dredger Application
Jet suction dredgers are primarily used for:
1. Sand Mining – Extracting sand from rivers, lakes, or coastal areas for construction materials.
2. River Dredging – Clearing sediment to maintain waterway depth and prevent flooding.
3. Port Construction – Excavating and maintaining harbors or channels for shipping access.
4. Gold/Gemstone Recovery – Portable models target mineral-rich sediments in shallow waters
