④The pH value of water is 6.5to 8.5.

⑤The content of chloride ions in the water does not exceed 400mg/L.

⑥The inner cavity of the water-filled motor must be filled with water or other aqueous solution configured according to the manufacturer's regulations.

Under the above-mentioned conditions of use, the average trouble-free running time of the motor can generally reach more than 2500h.When the conditions of use are harsh, and certain indicators or indicators such as the content of solids in the water, water temperature or pH exceed the requirements, the parts of the submersible motor for well use will accelerate the damage.
