ABSTRACT:
A pumping device secured to a well head adapted to be counter balanced and operated by well head gas pressure. The pumping cylinder and the counter balance cylinder are positioned on a prolonged axis and employ a common polished piston rod operably mounted on the axis of the cylinders. The counter balance piston is pressurized through a volume tank receiving gas through a pressure regulator from the well head. The pumping piston is powered up and down by direct pressure from the well head gas. The flow of gas to and from the pumping cylinder is controlled by a floating piston five-way valve admitting directly well head gas to drive the piston and exhausting the gas to the gas flow delivery line. Snifter valves control the floating piston five-way valve and pressure regulators positioned between the well head and the gas flow delivery line maintain operable differential pressure in the system.
