The pump must be completely submerged into water, but the submerged depth no more than 70 m.
Working conditions of submersible borehole pumps:
Three-phase power supply, voltage 380V (error less than 5%), frequency 50Hz (error less than 1%).
Motor must be filled with clean water.
Water temperatureshould not higher than 20 ℃.
Sand content of the water (by quality) not more than 0.01%.
Water PH 6.5~8.5.
The content of hydrogen sulfide in watershould not be more than 1.5 mg/l.
The content of chloridion in water shouldnot be higher than 400mg/l.
The water source must provide enough water for the pump to work continuously.
