Submersible mining dredger, also called submersible slurry pump dredger, is designed and manufactured with optimized hydrodynamic technology for sand dredging and silt clearing. OCEAN brand DMS series submersible mining dredger is equipped with our own specially designed submersible slurry pump, advanced suction reamer head and the famous brand motor. All of them are integrated together to realize high slurry suction ratio, more thorough dredging and large slurry or sand output.
In July, 2018, We got an inquiry of sand suction dredger from Nigeria. The customers required that the medium were sucked out was filled into Geo tube. Our submersible mining dredger can do this work, So we sent our catalogue of submersible mining dredger for reference.
In early April, we discussed about the submersible mining dredger requirement by email. Discussion content was as follows.
Q 1: We are looking for electric-driven sand dredger for dredging. Please provide us specifications of submersible mining dredger(discharge distance, lift, dredging depth, power, frequency, sand output, speed, etc.), together with your quotation.
A 1: Please check attached technical specifications of submersible mining dredger with all models .
The discharge distance depends on the lift .Dredge depth can be 25m .
Normally the power is 3 phase 380v, 50hz, and we can also customized it with 3 phase, 415V, 50hz, or 380v, 60hz.
The output of sand depends on the flow capacity, normally for the fine sand, the sand output is about 20% of the flow capacity and the coarse sand is about 15% of the flow capacity. And it also depends on the soft sand or sharp sand, etc.
Q 2.: What is the lead time of submersible mining dredger to the Nigeria? How much is the sea freight?
A 2: The delivery time depends on the model of submersible mining dredger, if there is no stock, the delivery time is 25 working days after deposit. The sea freight need to be calculated after confirming the sand dredger model .
Q 3: What is the best applicable pump for filling sand into the small holes of Geo tubes?
A 3:I think what u use is like Geo tube filling. Using this kind of submersible dredge pump just need the electricity and no irrigation water in. And using the hoses and valves to control the flow capacity to the Geo tube.
After communication about detailed information with clients for about 2 weeks, finally they confirmed 1 set of submersible mining dredger.

Customers wanted the submersible mining dredger urgently. We sped up the production. At the same time, one jet suction sand dredger was in production. Time is limited .
Within 25 working days ,we finished the submersible mining dredger and order the container for loading
Sticking on the product developing ideas of innovation, simpleness, quality and energy saving, we had been always focused on designing and manufacturing sand pump, slurry pump, gravel pump and sand dredgers since the foundation in 1997. Cooperated with domestic famous universities like Shandong University in sand pump research and development since 2005, we had obtained more than 15 patents, and become the leading sand pump brand in China. There are more than 3500 sets of sand pumps and dredgers running around the world. We had been provided professional pump solutions and services to over 60 countries.
