A submersible pump, which is the type most often used in drilled wells, consists of a pump and motor unit. The pump is placed directly into the well, below the water level. Jet pumps are not installed in the well, but installed above ground. Jet pumps operate by forcing water through a jet or Venturi, a narrow, cone-shaped device that creates a partial vacuum (suction) and draws water from the well into the pumping system. Shallow well jet pumps that are used where the water is less than 25 feet below the surface have the jet located in the pump itself.
