    Abstract: A pump control interface for use in a diaphragm pump including at least one diaphragm (26) adapted to move between a suction stroke and a discharge stroke during operation of the pump (24). A diaphragm follower (30) is connected for movement with the diaphragm during operation of the pump. A sensor mechanism (42) is provided for sensing at least the position and rate of movement of the diaphragm (26) by sensing the position and rate of movement of the diaphragm follower (30). In one embodiment, the control interface is provided as a rod (30) interconnecting two diaphragms (26,28) of a dual diaphragm pump (24) for synchronous movement. A plurality of conductive targets (40) are disposed on the rod (30), and a proximity (42) switch is mounted adjacent to the rod (30), in order to produce pulsed output signals when in proximity with the conductive targets (40).

    Abstract: A closed loop pneumatic pumping system is provided. The system uses a gas compressor and a high pressure gas tank to exert pneumatic pressure against a reciprocating piston over a wellbore. The piston is connected to a rod string and downhole pump for pumping formation fluids from a wellbore. The system includes an electronic controller that controls movement, including pump speed of the piston as it cycles between upstrokes and downstrokes within a cylinder over the wellbore. In one aspect, speed is controlled by adjusting a speed of the compressor. In another aspect, speed is controlled by adjusting the position of an upstroke control valve and a downstroke control valve. In one aspect, the pump stroke controller is configured to adjust a speed of the upstroke and a speed of the downstroke in response to signals indicative of pump fillage. A method for optimizing pneumatic pumping speed at a wellbore is also provided herein.
