TL;DR
A submersible pump is a sealed motor-and-pump unit that operates underwater at the bottom of a well, pushing water up the drop pipe rather than pulling it from the surface. Because pushing is far more efficient than suction lift, it is the standard for wells deeper than about 25 feet, with residential units typically 1/2 to 1-1/2 horsepower hanging on pipe, safety rope, and electrical cable below the static water level.

Service life runs 8 to 15 years, and replacement means pulling the entire string out of the casing.
