Dredging is the removal of sediments and debris from the bottom of lakes, rivers, harbors, and other water bodies using underwater sand dredger. It is a routine necessity in waterways around the world because sedimentation—the natural process of sand and silt washing downstream—gradually fills channels and harbors. Common dredgers in the international market include small dredgers, underwater sand dredger, jet suction dredger, cutter suction dredger, and trailing suction dredgers. The task of the dredger is to carry out the construction of underwater earth and stone by means of digging, widening and clearing the existing waterways and ports; digging new waterways, ports and canals; dredging docks, docks, ship locks and other water. The foundation trenches of industrial buildings and the dumping of the excavated sand into the deep sea or hydraulic filling in depressions on land for farming, etc. It is a weapon for blowing sand and reclaiming the sea.
In February 2021, our company successfully launched the underwater sand dredger SPD8115. The SPD8115 is a standard suction dredger designed for high-depth underwater sand pumping. The dredger has been fully installed and the accepted test procedure has been successfully completed. It has been delivered in April 2021.
Underwater sand dredger can realize the possibility of using submersible sand pump to extract sand from the bottom of the water. The submersible sand pump are explosion-proof and waterproof, and the extracted sand is used for filling, construction, etc.
The weight of SPD8115 is 13 tons, the total length of the structure is 8m, and the height is 1.5m. The underwater sand dredger is equipped with a powerful 120kW generator set, which is used for dredging sand with a dredging depth of -25 meters. The dredger is equipped with a submersible slurry pump and a submersible water pump for flushing in a separate pump room. It is also equipped with self-propelled capability and a propeller at the rear of the dredger. The mixed output of the high-efficiency dredger is approximately 240 m 3 / h.

OCEAN Pump engineers chose 6 inch submersible slurry pump according to the sand type, sand output and discharge distance. Secondly, we took SPD series underwater sand dredger hull as prototype and improved it. The improved hull structure can not only meet the submersible slurry pump and generator set size requirements, but also save cost.
This underwater sand dredger will be used for coastal beach tourism construction. It has passed a comprehensive test before leaving the factory. For all our dredgers, after-sales support and guarantee can be provided. During the COVID-19 pandemic, all the dredgers have been completed. The underwater snad dredger has overcome the challenges posed and fully considered the safety and well-being of all personnel and stakeholders.
