Jet Suction Dredger

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.
