Hydroman® Submersible Offshore Dredging Sand Pump Description:
Hydroman® Submersible Offshore Dredging Sand Pump are suitable to be used for pumping sand. Sand is pumped mixed with water up to 70% of solids by weight. The mixture of liquid and particles of sand and gravel is pumped in a procedure often used as a convenient way of handling sand and gravel. There are many applications for submersible sand pumps: sand and gravel extraction, dredging of rivers, harbors and marines maintenance or construction, beach reclamation, filling of Geotubes, among others. Here below you can read about some of the multiple applications of sand pumps.

Hydroman® Submersible Offshore Dredging Sand Pump Advantage：
▪ The motor of submersible slurry sand pump is made in all-copper core wire with stable speed and long service life.
▪ Hydroman® submersible dredging slurry pump with thickened pump body is more wear-resistant,our submersible slurry pump weight is twice that of other suppliers.
▪ Submersible dredging agitator pump installed in unique double mechanical seal effectively prevents impurities from entering the inner cavity.
▪ Submersible muddy water agitator pump has double shaft seal for high-strength seal without leakage.
▪ Hydroman® submersible sand pump is equipped with the motor with low speed, high number of motor stages, large torque, safer for high-power loads.

Hydroman® Submersible Offshore Dredging Sand Pump Application:
▪ Mine Pits Dewatering
Pit-installed pumps on pontoons or barges commonly use submersible mine dewatering pump. For booster stations submersible pumps connected in series, single-stage end-suction or multistage pumps can be used. These solutions can be provided in containerized units for ease of installation and transportation.
▪ Underground Mine Dewatering
Submersible underground mine pumps are used to remove water from mine faces nd stopes. Water is transported in stages to collection stations where larger pumps are located along the drift and ramp. Normally smaller submersible drainagepumps are used at the mine faces.
▪ Shaft bottom drainage
Mine water from all parts of the mine is collected by submersible dewatering mud pump in the shaft bottom sump and then transported to the main drainage pump station. The high-performance submersible electric slurry sludge pumps fulfill the requirements, meeting the demands for both high head and high volume
▪ Tailings Ponds and Mineral Recovery
The scarcity and cost of water means that wastewater treatment and recycling for reuse are important processes within mines. Water is reclaimed from tailings ponds, lagoons and the downstream of minerals processing by vertical sump slurry pump, horizontal sludge pump and submersible sand pumps.
▪ Water treatment
Minerals processing requires process water feed at various stages. The quality of the water is highly important and therefore some level of treatment is needed before it enters the process. A combination of submersible water treatment sludge pumps, horizontal process pumps and vertical mineral processing pumps are commonly used in the feed to the proces.
▪ Mine sites
Other common applications for pumps at mine sites are tire washing plants, washdown of plant and machinery, and dust suppression. These may be fed by submersible slurry pump.
