2. Product overview :

QJ series deep well submersible water pumps are widely used in farm irrigation, sprinkler irrigation, getting water 

from well, water supply and drainage system for industrial and civil building,  water diversion project in hilly and

mountain areas water drainage project in at low-lying areas, water supply and drainage in urban and rural’s mining enterprises and  various ther kinds of water conservancy facilities. Its features are that the Motor and pump are assembled 

into a whole, so that it is simple in structure, convenient to assemble and disassemble ,easy to use and maintain safe to operate. Otherwise,  it covers an small area and does not pollute water.
