QJ Deep Well pump is used to draw ground water from a deep well, or from river, reservoir and aqueduct etc. mainly for agricultural irrigation, water for human being and livestock in plateau areas, water discharge in cities, factories, mines and construction sites.

Product feature

1.Integrated body of motor and pump, submerged operation of great safety.
2.No special requirements on borepipe and ascending pipe(i.e. it can be used in steel pipe well, ash pipe well and shallow well; if pressure permits, steel, rubber and plastic pipes can all be used as ascending pipe)
3. Easy installation, operation and maintenance, small occupation space, and no need of a pump room.
4.compact and simple structure and small volume.
