        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.

    Its performance is driven by integrated cutter suction engineering: a high-hardness, high-chromium alloy rotating head pulverizes underwater obstacles and compacted sand, feeding directly into a high-flow pump for instantaneous removal. This method achieves complete extraction with no residual pockets. With a customizable daily output range of 500 to 10,000 cubic meters, it outperforms traditional dredgers by 30% in overall efficiency. Engineered for versatility, it operates effectively in water depths ranging from 0.5 to 15 meters, adapting to both shallow nearshore zones and deeper waterways.
