Sand mining dredger (ZJQ series)  is designed and manufactured with optimized hydrodynamics technology for sand suction and silt clearing. This kind of sand mining dredger is driven by electric motor. The sand mining dredger is suitable for conveying liquid with solid particles including sand, gravel, cinders and tailing etc. The sand mining 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 sand mining dredger will have long-term bearing life.  Sand mining 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 slurry pump dredger for the sea 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.

In July, 2018, We got an inquiry of sub dredge from Philippines. The customers required that the medium were sucked out was filled into Geo tube. Our submersible slurry pump dredger could do this work, So we sent our catalogue of submersible slurry pump dredger for reference.

After Communicating detailed information with clients for about 1 month, finally they confirmed 3 set of submersible slurry pump dredger.
