The difference between submersible pumps and centrifugal pumps
The two are different ways of distinguishing.Centrifugal pump is in accordance with the impeller type of a pump, that is, centrifugal pump impeller is centrifugal.Submersible pump refers to its working environment is underwater, it is divided by the application environment, it can also be centrifugal pump or axial flow pump or mixed flow pump, the key is to see what kind of impeller is.Submersible pump motor is required to dive, that is, the motor protection level is relatively high, generally more than IP68 in order to dive.
Submersible pump refers to the installation of pumps in the form of motor and pump body are installed underwater. It can be a sewage pump or a clean water pump or other purpose.Sewage pump to see the name will know, that is, playing sewage, you can use submersible pumps, you can also use other forms of pump.
Difference：The installation position is different: one can discharge water, one is on the ground.Working principle: different submersible pump principle similar electric fan, centrifugal pump by centrifugal force makes the water thrown out. According to the design principle of centrifugal force, high speed rotation of the impeller blades to drive the liquid will rotate out of the liquid, so as to achieve the purpose of transportation. There are many medium for transportation, such as oil, water, chemicals and so on. The pump shaft and the motor shaft are of the same shaft, the pump and the motor are made into an integral body and immersed in water. The medium of transportation is water.
