1、Different purposes:Centrifugal pumps can be widely used in industries such as power, metallurgy, coal, and building materials to transport slurries containing solid particles. Submersible pumps are mainly used for agricultural irrigation and water supply for people and livestock in high mountain areas. They can also be used for central air conditioning cooling, heat pump units, cold pump units, urban, factory, railway, mining, and construction site drainage.
2、Different structures:A centrifugal pump consists of an impeller, pump body, pump cover, water blocking ring, pump shaft, bearings, sealing ring, packing box, axial force balancing device, etc. The submersible pump set consists of a control cabinet, submersible cables, lifting pipes, submersible electric pumps, and submersible motors.
3、The working principle is different:The principle of a submersible pump is similar to that of an electric fan, where the pump and motor are integrated and immersed in water. The conveying medium is water. The centrifugal pump is designed based on the principle of centrifugal force to expel water. The high-speed rotating impeller blades drive the liquid to rotate and expel it, thereby achieving the purpose of transportation. There are many media that can be transported, such as oil, water, chemical raw materials, etc.
4、Different installation methods:Centrifugal pumps are installed on pipelines, while submersible pumps need to be placed in water for pumping.
5、Significant differences in energy consumption:Due to the need to introduce air to form vortices, centrifugal pumps consume more energy compared to submersible pumps.
