Installation location is different: one can be placed in the water, one on the ground
The working principle is different: the principle of the submersible pump is similar to that of the electric fan. The centrifugal pump pushes the water out by centrifugal force. According to the principle of centrifugal force, the impeller blades rotating at high speed drive the liquid to rotate, and the liquid is thrown out to achieve the purpose of transportation. There are many media that can be transported, such as oil, water, and chemical raw materials. The pump shaft and the motor shaft are the same shaft, and the pump and the motor are integrally immersed in water. The transport medium is water.
