Submersible Sand Jet Suction Digging Dredger  (ZJQ series)  is designed and manufactured with optimized hydrodynamics technology for sand suction and silt clearing. This kind of Submersible Sand Jet Suction Digging Dredger  is driven by electric motor. The Submersible Sand Jet Suction Digging Dredger is suitable for conveying liquid with solid particles including sand, gravel, cinders and tailing etc. The Submersible Sand Jet Suction Digging Dredger is mainly used in ribver, lake sand dredging, metallurgical industry, mining and thermal power plant, etc. It’s wear resistant wet parts are made of hard metal (Chrome alloy).  The bearing assembly is composed of large diameter shaft and short overhang, so the Submersible Sand Jet Suction Digging Dredger will have long-term bearing life.  Submersible Sand Jet Suction Digging Dredger has the characteristics of high efficiency, energy saving, simple operation and easy management.

1. High efficiency. The motor submerges under water so that its operation is not restricted by suction head, realizing high dredger suction ratio and more thorough dredging.
2. Best wear-resisting .Flow passage component of the pump is made of wearable high-chromium alloy material with good wear-resisting property and big flow passage way, making it suitable for transportation of mediums including mud with big solid particles, ore pulp, coal pulp and coarse sand etc.
3. Triple protection. Equipped with sensing probe of the motor to realize over-heating protection, water-intake inspect protection and oil chamber protection, ensuring long and safe pump operation under abominable working conditions.
4. Convenient and Cost saving. The entire equipment is simplified without auxiliary mixing equipment or injecting device, making the operation more convenient and the total investment lower.

1. Submersible Sand Jet Suction Digging Dredger is vertically submerged under water and driven by electric.

2. Suitable for conveying liquid with slurry, solid particles of gravel, cinders, tailings, etc.

3. Commonly used in river dredging, sand pumping vessel, sewage treatment plants, metallurgical industry, mining, power plants, etc.

Submersible Sand Jet Suction Digging Dredger  is designed by OCEAN Pump industry for such applications as sand pumping, sea reclamation and mining operations, etc. Through on-site investigation of users and communication with ship design experts, our engineer team designed the Submersible Sand Jet Suction Digging Dredger equipped with ZJQ submersible slurry pump, and adopted optimized mechanics technology for sand pumping, sea reclamation and dredging. OCEAN Pump brand ZJQ submersible pump dredger with many characteristics such as high efficiency, energy saving, simple operation, convenient management and so on.

A representative of a Maldivian reclamation contractor visited our company.  The customer wanted to buy a dredger that can suck sand out of the sea. The suck depth was about 1 m to 3 m, and the discharge distance was about 150 m. The sand grains were fine sand, and the island area is filled with fine sand.

Submersible Sand Jet Suction Digging Dredger parameter:

The Submersible Sand Jet Suction Digging Dredger was shipped to Maldives, and the engineer designed the hull to disassemble and assemble easily, so the installation was very simple. The customer completed the installation within one day, the local sand source was very good,  and the sand pumping operation started successfully, ZJQ submersible slurry pump worked smoothly, sand output per hour reached 30 cubic meters, discharge distance reached 150 meters. Our customer was very satisfied with our Submersible Sand Jet Suction Digging Dredger product and professional services.
