The custom jet suction dredger features a high-pressure water jet system and a powerful sand suction system. Specifically, it utilizes high-speed water jets to remove sediment and sand, allowing it to effectively clear materials from the seabed or riverbed. The water jet system agitates the sediment, while the suction system collects the loosened material and transports it through pipelines to storage or processing areas.
Moreover, these sand suction dredgers commonly support dredging projects that maintain waterways, deepen channels, or reclaim land. Consequently, this custom jet suction dredger excels in underwater sand or slurry excavation operations at depths ranging from 1 to 20 meters. Its primary function is to extract sand or sediment from underwater and transport it to designated locations to meet various utilization needs. The Sand Dredging Machine developed by OCEAN Pump generates a high-pressure water impact at the bottom of the sand layer, creating a vortex effect to direct mixed sand around the suction nozzle. Consequently, the sand pump then transports the extracted material through pipelines or conveying systems to barges or shore locations for final deposition or utilization.
Ultimately, the Jet Suction Dredger serves as a powerful and versatile vessel that enables efficient dredging operations. This indispensable machine plays a crucial role in channel cleaning, waterway maintenance, and the restoration of global ecosystems.

To meet different customer needs, OCEAN Pump, the manufacturer of the jet suction dredger, offers OEM (Original Equipment Manufacturer) and ODM (Original Design Manufacturer) services, as well as customization options.
During dredging operations, the Jet Suction Dredger relies on a horizontal sand pump. A production floating platform supports this operation, ensuring the normal functioning of the sand pump. OCEAN Pump provides customized platform size solutions for various types of sand dredging machines, ensuring the stability and reliability of the vessel’s structure. For transportation convenience, OCEAN Pump’s Jet Suction Dredgers typically design as detachable three-part structures, which include one central floating box, two side floating boxes, and a gantry.
The sand suction system is an essential component of the Jet Suction Dredger. Its core consists of the integration of the sand pump and diesel engine. The centrifugal sand pump generates centrifugal force through high-speed rotation, sucking the mixture of sand and water into the pump through the suction nozzle and transporting it to the designated location via the discharge pipeline. OCEAN Pump offers a wide variety of sand pumps with different types and models to meet the diverse needs of customers in dredging operations. For applications requiring high flow rates and short-distance transportation, we recommend the cost-effective portable sand pump unit, which features a belt connection to a land-based diesel engine for easy operation. For high flow rates and long-distance transportation requirements, we provide heavy-duty sand pump series, slurry pump series, and gravel pump series sand pump units.
OCEAN Pump’s Jet Suction Dredger is equipped with an efficient water jet system, which has been carefully designed and modified. This system involves the installation of high-pressure water guns near the suction head to generate strong water jets that impact the bottom sediment, creating a vortex effect. This effect significantly enhances the concentration of the pumped sand and improves the efficiency of the sand suction operation. Setting the correct pressure for the water pump is crucial to achieve optimal results. If the pressure is too low, the sand cannot agitate effectively; conversely, excessively high pressure may cause the sand to disperse too much, resulting in a lower sand concentration. Therefore, it is essential to accurately select a high-pressure water jet pump based on the flow rate of the sand pump, dredging depth, and sand characteristics.
OCEAN Pump provides various connection options for high-pressure water jet pumps to meet different requirements. For Jet Suction Dredgers with high flow rates and short-distance transportation, we recommend a direct connection to the diesel engine and winch, thereby ensuring strong power output. For Jet Suction Dredgers requiring long-distance transportation, we suggest a design where the high-pressure water jet pump shares a marine diesel engine with the sand pump. This design not only saves valuable cabin space but also simplifies the operation process and improves work convenience.
The lifting system is an indispensable part of the Jet Suction Dredger, and its operation relies on controlling and adjusting the rubber hose and sand suction nozzle’s lifting movements. Controlling the position of the suction nozzle ensures the appropriate extraction concentration. This process is mainly achieved by the winch, which can be driven by a diesel engine or an electric motor. When selecting the winch, it is essential to consider the total weight of the suction head, suction rubber hose, and flushing rubber hose, as well as the downward force generated by the sand pump in operation. OCEAN Pump’s gantry is manufactured using high-strength and high-quality steel materials to ensure excellent load-bearing capacity and stability. Additionally, precise planning of the gantry’s installation position and height is necessary to maintain the overall balance of the jet suction dredger.
The movement system is an optional configuration for customers and consists of a propeller and a diesel engine. The propeller, a marine propulsion device, generally connects to the diesel engine via a belt. Its characteristics include smooth propulsion speed and easy operation, supporting both forward and reverse movement of the vessel while adjusting the sand dredger’s direction.
After the sand is extracted by the sand pump, it is transported through a pipeline. The pipeline system mainly consists of HDPE pipes and floaters, with the floaters serving to keep the pipeline afloat on the water surface. According to OCEAN Pump’s professional advice, each pipeline should be equipped with two or three sets of floaters to ensure stable and reliable floating performance. The floaters are made of high-density polyethylene (HDPE) material, which is durable, corrosion-resistant, and has excellent buoyancy properties. Furthermore, the pipeline system is designed to minimize friction loss and maintain a smooth flow of the transported sand-water mixture. The length and diameter of the pipeline can be customized according to the dredging distance and required flow rate.
Jet suction dredgers are widely used in coastal engineering projects. They extract sand from offshore areas and deposit it onto eroded beaches, thereby replenishing and restoring them. This practice helps protect coastal areas from erosion and storm damage.
Ports often require regular maintenance to ensure safe navigation of vessels. Jet suction dredgers remove silt, sediment, and other debris accumulating in the channels, berths, and docking areas. This maintenance helps maintain the required water depth and ensures smooth operation of vessels.
Jet suction dredgers play a crucial role in land reclamation projects. They extract sand from underwater locations and deposit it in designated areas to create new land for development purposes. This process is particularly useful for expanding coastal areas, constructing artificial islands, or reclaiming land for infrastructure projects.
Over time, rivers and channels can experience sedimentation, which affects their navigability and water flow. Jet suction dredgers remove accumulated sediment, silt, and debris from riverbeds and channels, thereby restoring their capacity and maintaining water flow for irrigation, flood control, and shipping.
Jet suction dredgers are used in mining operations to extract valuable minerals and materials from underwater deposits. They remove sand, gravel, and other aggregates from the seabed or riverbed, which can be processed for various industrial applications, including construction, concrete production, and infrastructure projects.
Jet suction dredgers help remove contaminated sediment, pollutants, and debris from water bodies, lakes, and harbors during environmental remediation projects. This process improves water quality, restores aquatic habitats, and mitigates the impacts of pollution.
Finally, jet suction dredgers are used in beach nourishment projects, where sand is extracted from offshore sources and placed on eroded beaches. This practice helps expand and enhance beach areas, providing recreational spaces while protecting coastal communities from erosion.
