Title: Dual valve well pump installation

Abstract

A reciprocating electric motor-pump assembly for lifting well fluid on downstroke of the motor pump assembly, the pump including a barrel below the motor having dual combined inlet and outlet valve means at the lower end thereof, the pump piston moving in the barrel having annular grooves therearound to prevent differential pressure sticking, the electric cable supplying the electric motor being tubular to vent the pump and prevent vacuum or gas lock, there being a packer about the valve barrel separating the outlet valve means thereabove from the inlet valve means therebelow and a packer above the motor about a production tubing including an upper standing valve.
