Our products include H-series dredges, L-series dredges, convac system, LCAP system, velocity meter and water pumps. Our H-series hullpump dredge is the choice for aggregate production from shallow and medium depths. Our opendeck design allows for easy maintenance and eliminates the open hull that can literally sink competitive dredges. Our ladderpump dredge potential can realized if the dredge is equipped with a cutter to make solids available at the suction inlet combined with instruments and controls to monitor & maintain continuous production.
