Submersible Borehole Pumps System
Borehole pumps are consists of submersible motors, inlet, outlet and impellers. As submersible borehole water pumps are usually used under well, multistage style is adopted to ensure efficiency of pump working.
Submersible motors keep pump working into water for a long time without burning. Water cooler motor and oil filled motor can be chosen. Besides, cast iron and stainless steel one can also be chosen according to actual usage conditions.
Stainless steel type is made by 304 stainless steel, whole pump body is promised to be corrosive resistance. Water quality can be well guaranteed. Cast iron submersible pumps are excellent in wear resistance and hardness. Both of them are of high quality and can be used according to usage situation.

Submersible Borehole Pumps vs. Centrifugal Pump
Submersible borehole pumps need to be used under water, especially used under deep well. Therefore, submersible motors need to be installed inside. On the contrary, centrifugal pump can be used either on the ground or under ground. When it is used under ground, it becomes one kind of submersible pumps. While it is used on the ground, air cooler submersible motors would be installed inside.
Impellers of this two kinds of pumps are also different, centrifugal pumps use centrifugal impellers. When they are operating, highly rotated impeller gives water centrifugal force, so water can be drainage out.
Division of centrifugal pump and borehole submersible pump relies on their working conditions and working principles. But borehole pump is actually a part of centrifugal pump, so most of their performances are similar.
Submersible Borehole Pumps Working
Before operating, suction tube and pump must be filled with fluid. When water pump is on, fluid will rotate with highly rotated impeller. Then fluid will be thrown away from it, and flow into diffusion chamber. The speed of fluid will slow down gradually, while pressure is added. Then transferred fluid will flow out of pump under great pressure. Vacuum space is formed at the entrance of pump, then new fluid will be pumped in again.
