Jet pumps are commonly used to extract water from water wells. The main
pump, often a centrifugal pump, is powered and installed at ground level. Its
discharge is split, with the greater part of the flow leaving the system, while a
portion of the flow is returned to the jet pump installed below ground in the well. This recirculated part of the pumped fluid is used to power the jet. At the jet pump, the high-energy, low-mass returned flow drives more fluid
from the well, becoming a low-energy, high-mass flow
which is then piped to the inlet of the main pump.

A Submersible pump (or electric submersible pump (ESP)) is a device which has a hermetically sealed motor close-coupled to the pump body. The whole assembly is submerged in the fluid to be pumped. The main advantage of this type of pump is that it prevents pump cavitation, a problem associated with a high elevation difference between pump and the fluid surface. Submersible pumps push fluid to the surface as opposed to jet pumps having to pull fluids. Submersibles are more efficient than jet pumps.
