        Jet Suction Dredger

        The jet suction dredger is a vessel that integrates the functions of impact, stirring, suction of sediment, and transportation. Its core mechanism is that a high-pressure water pump generates a high-pressure water flow to impact the bottom sediment, making it moist and disintegrate into slurry. Subsequently, through negative pressure, the slurry is sucked into the designated area by the suction pump, thereby enabling the dredging and silt removal operation in shallow water areas.

    The Jet Suction Sand Dredger from Duohui represents a paradigm shift in lightweight dredging efficiency. It is a multifunctional mining platform that seamlessly integrates suction, transport, and dredging operations, purpose-built for global applications such as sand extraction, river desilting, and sludge management.

    The key differentiator lies in its cutter-free jet suction mechanism. Instead of mechanical agitation, it relies on focused high-pressure water jets to loosen and suspend bottom sediments. A high-power suction pump then lifts the slurry in a continuous, residue-free operation. This method delivers powerful suction with no dead zones. With a flexible daily output of 300 to 8,000 cubic meters, the dredger adapts to varying project scales and water depths ranging from 0.3 to 12 meters.
