Submergence of dry motor submersible pump
(OP)
When i came across the dry motor submersible pump the motor has a limitation that it cant be used above 20m.whereas the wet motor submersible pump can be used till 350m.can i know why?pls advice.

If that's not the answer, I don't know what is. We'll see if anybody else can suggest something different.

The answer is the delta pressure. “Wet” motors used in the petroleum industry are installed to depths exceeding 15000 feet (4572 M) without problems. Submerged static pressures > 6000 PSI are not uncommon. The trick is to keep the pressure inside the motor and outside the motor equalized. Dry motors and / or water well type motors are limited by collapse pressure of the motor housing.

Some water filled water-well motors have limited pressure equalization capacity. They can be used deaper than dry motors, but there are limits.
