SUBMERGIBLE PUMP INSTALLATION Abstract of the Disclosure A submergible pump installation for wells comprising a submergible pump assembly adapted to be landed in position within the well bore for pumping well fluids to the surface, together with a safety system for the well including a sub- surface valve or valves for maintaining the well under control as the pump is run into and removed from the well. At least one subsurface valve of the system is hydraulically actuated by the discharge pressure of the pump with the pressure fluid being conducted to the valve by a conducting means located exteriorly of the pump housing. The invention also contem- plates the use of a novel poppet-type subsurface valve which may be suitably pressure balanced so that it is capable of being actuated by relatively low hydraulic control pressure supplied by the pump. This invention relates to new and useful improvements in submergible pump installations for wells and more particu- larly, to a safety system which maintains the well under control as such installations are run into or removed from the well. The invention also relates to a novel poppet-type safety valve used in said safety system.
