Submersible dewatering pump has the following application scenario.
1.The water in pit bottom with large range for lift and down, it is easy to sink the centrifugal dewatering pump.
The open-pit mine is the same like a big basin. When the rainy season comes, a large amount of rainwater collects to the bottom of the pit with mud and sand, and the water surface rises quickly. When using a centrifugal pump for drainage, due to the limitation of suction, the centrifugal dewatering pump can only be placed on the shore closer to the water surface. The skyrocketing water surface during the flood season can easily submerge the centrifugal dewatering pump and cause the drainage system to be paralyzed.
2.The submersible dewatering pump with high pressure water hose can be installed on the floating dredger
Floating dredger occupy big space, it is suitable for the big and deep water pit and also need big flow filling in. Some open-pit in north of China with less water in dry season. It is hard to use this dredger, and if it is not safe if made the small dredger, and if dredger big, the cost is high.
When digging the pit bottom, the water is often mixed with sand, the water pump is easy to worn out.
When working, the excavator makes the sand mixed with water to form the slurry. To ensure the working process, it is no need to wait the slurry completely sink, submersible dewatering pump should work before he slurry completely sink. It is easy to worn out if has no enough water.
3. The submersible dewatering pump is easy to sink into the slurry.
a. Most of the submersible pump is used for water on the market. When the water mixed with sand, the pump is easy to worn out .
b. Simple submersible water pump needs to completely sink in the water when running, it can not out of water level when working. So the site needs to dig a deep pit, and it needs to keep the pit with enough water when working.
c. Big submersible water pump is so heavy that it can not be lifted easily, so the submersible dewatering pump is feasible for the water at the pit bottom. Most of submersible water pump is pumped from the bottom. If there is no base at the pump pit, the submersible water pump is easy to sink in the slurry .
d. Submersible water pump is installed underwater, daily maintenance is not easy especially when the water level up. The installation location will be far away, it is also hard to disassembly ,
E:With heavy rain, the flood with lots of slurry will filling the mining pit and if strictly the pump will be buried .
