As far as the medium is concerned, submersible pumps can be roughly divided into three categories: clear water submersible pumps, sewage submersible pumps, and seawater submersible pumps (corrosive).
QJ-type submersible pump is a water-lifting machine that is directly connected with the motor and the water pump to submerge into the water. It is suitable for extracting groundwater from deep wells, and can also be used for water-lifting projects such as rivers, reservoirs, and canals. It is mainly used for farmland irrigation and human and livestock water in plateau and mountainous areas. It can also be used for water supply and drainage in cities, factories, railways, mines, and construction sites.

Features
1. The motor and the water pump are integrated, submerged in the water to run, safe and reliable.
2. There are no special requirements for well pipes and water lifting pipes (ie: steel pipe wells, ash pipe wells, earth wells, etc. can be used; steel pipes, rubber pipes, plastic pipes, etc. can be used as water lifting pipes under pressure permission).
3. The installation, use and maintenance are convenient and simple, the floor area is small, and there is no need to build a pump room.
4. The result is simple and the raw material is saved. Whether the conditions for the use of submersible electric pumps are suitable or not, and proper management are directly related to the service life.
