When we used the wet submersible pump, we found that some production teams in the countryside did not add clean water to the motor, but opened the water inlet and the water outlet, and the motor circulated by the water in the well while working Cooling, this is not good. One of the main features of a wet submersible pump is to add water to the motor to cool it, which is the main difference from an oil submersible pump.
