Jet suction dredger is widely used to recover materials from great depths and can also extract sand from below a clay overburden which is also called jet sand suction dredger. Jet suction dredger is equipped with high pressure water pump and powerful sand suction pump. The water pump can produce high pressure high speed water jet to impact the bottom of sand layer and splashing the mixed sand around the suction head, and the sand suction pump conveys the sand to the destination through the discharge pipe.

A jet suction dredger is a highly specialized piece of equipment used for dredging operations. It plays a crucial role in various marine and inland waterway projects. By utilizing the power of high - pressure water jets and suction mechanisms, it can efficiently remove sediment, debris, and other materials from the bottom of water bodies.

The Jet Suction Dredger 300 (JSD300) is a mid-sized hydraulic dredging vessel designed for efficient removal of loose to moderately compacted sediments in shallow to medium-depth water bodies (≤15 meters). Named for its 300-mm diameter suction nozzle and pipeline system, the JSD300 combines a high-pressure jetting system (5 bar nominal pressure) with a centrifugal dredge pump (298 kW) to fluidize and transport sediments as a slurry.

The JSD350 jet - suction dredger is a highly efficient dredging equipment. It is mainly used for dredging operations in rivers, lakes, ports and other waters, capable of sucking and transporting sediment, sand and other substances. Equipped with a powerful jet - suction system, it can quickly suck up sediment and discharge it to the designated location through pipelines. With a certain dredging depth and flow capacity, it can meet the needs of different engineering projects, and plays an important role in waterway maintenance and land - reclamation projects.

A jet suction dredger is a specialized piece of marine equipment designed to remove sediment, debris, and other materials from the bottom of water bodies such as rivers, lakes, ports, and seas. It operates on the principle of using high - velocity water jets to loosen and fluidize the sediment, which is then suctioned up through a pipeline and transported to a designated disposal area.​
