QJ type deep well submersible pump selection instructions:

1. Measure the diameter of the wellbore. The size of the selected deep well submersible pump should be smaller than the diameter of the wellbore to maintain sufficient clearance between the well and the pump.

2. Measure the actual depth of the well, the static water level. And through the pumping test, the dynamic water depth of the well is obtained.

3. Calculate the pipe total length of the QJ deep well pump in the well according to the dynamic water depth, and calculate the total loss head to determine the required pump head.

4. Determine the number of stages of the submersible pump impeller. The rated head of the selected pump should not be less than the calculated head.
