QJ Series electric centrifugal diving water pump​

Summary
QJ series deep well submersible pump is a water drawing machine dives into water to work, which intergrates the motor and water pump. 
 
CharacteristicCCha
1. The motor and the water pump are intergrated and dive into water to work, which is safe and reliable.
1. No special requirements for the well tube and lifting pipe(that is, it can be used for steel pipe well, ash pipe well, shallow well and so on; steel, rubber and plastic pipes and so on can all be used as the lifting pipe if permitted by the pressure. )
2. Easy for installation, use and maintenance; small occupation, no need of building up a pump room.
3. Simple in structure, thus saves the raw materials.
 Whether the working condition and management of pump are proper is directly related to its service life.

Application:
