. TAIAN OCEAN PUMP
Jet Suction Dredger, diesel/electric – driven. For calm waters, efficiently clears sediment, sludge, sand from river, lake, coastal bottoms.
About
The custom jet suction dredger, equipped with a high – pressure water jet and a strong sand suction system, uses high – speed water jets to stir up seabed/riverbed sediment. The suction system then collects and pipelines the loosened material.
It’s used in dredging projects for waterway maintenance, channel deepening, and land reclamation, especially in 1 – 30 meters – deep underwater sand/slurry excavation. Developed by OCEAN Pump, the high – pressure water jet creates a vortex around the sand suction nozzle, and the sand pump transports the extracted material to barges or shore.
This powerful and versatile dredger is essential for channel cleaning, waterway maintenance, and ecosystem restoration.

Advantages
3.1 Modular Design and High – Efficiency Power
The jet suction dredger adopts a modular design and can be configured as needed. It can be powered by either diesel engines or electric motors, and is equipped with an optimized high – pressure water jetting system and an efficient sand pump suction system.
3.2 High – Quality Wear – Resistant Parts and Appropriate Dredging Depth
The flow parts of the sand dredging pump can be made of either medium chrome alloy or high chrome alloy to meet the requirements of wear resistance and corrosion resistance. The dredging depth range is typically 1 – 20 meters, and the pumping depth of the pump is also suitable for different working conditions.
3.3 Low Investment, High Return and Convenient Operation
The design takes cost – effectiveness into consideration, and the return on investment can be achieved in just 80 effective working hours. The assembly and disassembly are simple and easy, and the operation process is simple and user – friendly.
3.4 Detachable Sand Dredging Vessel and Customization Services
The sand dredging pump is designed as a detachable vessel with dimensions compatible with shipping containers, ensuring easy transportation. OEM, ODM, and customization services are provided.
Main Components
4.1 Production Floating Platform
During dredging, the Jet Suction Dredger’s horizontal sand pump is supported by a production floating platform. OCEAN Pump offers customized platform sizes. The dredger is usually a detachable three – part structure for easy transport, with a central box for pumps and side boxes for buoyancy. Openings on side boxes and optional features like cabins are available.
4.2 Sand Suction System
The sand suction system, a key part of the Jet Suction Dredger, combines a sand pump and diesel engine. OCEAN Pump offers various sand pumps. For high – flow short – distance needs, a portable unit is recommended; for long – distance, heavy – duty pump series are provided.
4.3 Water Jet System
The Jet Suction Dredger has an efficient water jet system with high – pressure water guns near the suction head. Proper water pump pressure is crucial. OCEAN Pump offers different connection options for high – pressure water jet pumps based on transport distance.
4.4 Lifting System
The lifting system of the Jet Suction Dredger controls the rubber hose and sand suction nozzle. The winch, driven by diesel or electric motor, is selected considering the weight of components. The gantry, made of high – strength steel, requires precise installation for balance.
4.5 Movement System
The movement system, optional for customers, consists of a propeller and diesel engine. The propeller, belt – connected to the engine, enables smooth vessel movement and direction adjustment.
4.6 Pipeline System
The pipeline system, mainly of HDPE pipes and floaters, transports sand after extraction. Each pipeline should have 2 – 3 sets of HDPE floaters for stability. The pipeline length and diameter can be customized according to dredging needs.
