Features

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.

Application

1. Sand 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.

Successful cases

Sand dredger is the kind of dredging machine equipped with submersible slurry pump which is mainly used to dredging the river, lake to deepen the river or lake bed, ensure the rain season with enough place for more water and sludge. OCEAN Pump Brand sand dredger is the ideal equipment to dredge sand, gravel, solids and all kinds of sludge in diverse applications related to the sand mining, slurry dredging in construction, oil and mining industry as well as marine, energy, and industrial applications.

Requirement of  sand dredger for tourist resort dredging in Thailand

1. Rainy season had much water, the tourist resort needed to dredge the river or lake to ensure the water pass.

2.Some place the water quality was not good which needed to dredge the bottom sludge or slurry to make the water clear.

Solution of sand dredger

With lots of dredging experience, we make the special sand dredging equipment with submersible slurry pump for this kind of working condition. 

1. Easy Operation: The sand dredger is composed of submersible slurry pump, pontoon, sound proof generator, discharge pipe. All of these are easy to operated, when arrived at working site, the customer just need to make assembly and operate it.

2. Low Noise: The generator with sound proof can make the submersible slurry pump dredger with low noise.

3. Small Space Occupy: The sand dredger is a small pontoon, which can be moved by remote control in the small river or canal.

4. High Efficient with Bottom Agitator: The sand dredgerr pump can be equipped with bottom agitator which can mix the bottom slurry up and then pump the slurry out and if you want to finish the project in short time, suggest this sand suction dredger.

5. Environmentally Friendly

6. Low Fuel Consumption

In May, 2019, customer from Thailand inquire this kind of sand dredger for his holiday resort dredging. After communicating the working condition, we choose the ZJQ 300-20-37 sand dredger pump and the suitable pontoon for customer request and customer prefer to use the remote control for the project, we can also reach it! After 2 months communication, customer make the deposit for this project and products are also on schedule!
