Abstract
A well pump system includes a fluid pump having an inlet and a discharge. The inlet and discharge are separated longitudinally by an inflatable annular seal. An inflation line extends between the discharge and an inflation inlet of the inflatable annular seal. A pressure relief is operable to direct flow from the discharge to the inflation line. The pressure relief is operable to open the discharge to flow to surface in the well when a predetermined fluid pressure is reached. The system includes means for opening the inflation line to release pressure in the inflatable annular seal when a selected tension is applied to the well pump system.
