Jet Suction Dredger
Dredging Vessels
Ideal for dredging and sand extraction in rivers, artificial lakes, reservoirs and ports
- Dredging depth: up to 18 meters
Our Jet Suction Dredger is the perfect solution for your sand extraction needs. It uses a high-pressure water pump to generate powerful jets that break up the sediment at the bottom.
Once the sediment is loosened, the sand pump creates strong suction to draw up the slurry mixture of sand and water, which is then transported through a suction pipe to the vessel’s hold or directly discharged to your desired location.

The Jet Suction Dredger is widely used for dredging and sand extraction in areas with fewer rocks, such as ports, artificial lakes, reservoirs, rivers, and river dams. Thanks to its innovative design, ease of operation, and high efficiency, the Jet Suction Dredger plays a key role in river, lake, and sea dredging, as well as in reservoir sand extraction, reclamation projects, and port dredging.
