Abstract: A well pump for use in oil wells, and the like, consisting of a series of cylinders connected by a production tubing and an air circulation system having two conduits extending into the casing-tubing annulus, each cylinder having an inlet connection through the top thereof and into one of said lines, alternately, so that every other cylinder is in the same line, and a four way valve in a control box at the well head, operated by an electric motor for alternating the flow of air through the respective conduits into the cylinders, the production tubing forming a dip tube in each cylinder, and check valves at the lower ends of each cylinder to prevent backflow, the bottom cylinder being the control cylinder having a fluid level controlled switch which activates the pump, sending a charge of air into the respective cylinders, lifting the production fluid therein progressively to the earth's surface.
