Abstract
A diaphragm pump and pump system including a pump housing defined along a longitudinal axis and having one or more pumping chambers and one or more driving chambers. At least two check valves communicating with each of the one or more pumping chambers for conducting a production fluid into and out of the pumping chamber. One or more flexible axially elongated diaphragms are mounted in the pump housing and sealingly separate the one or more pumping and driving chambers. At least one cam mechanism is disposed in the pump housing and coaxially therewith the pump housing longitudinal axis. The cam mechanism is configured for rotational movement to provide for radial deflection of the one or more flexible axially elongated diaphragms into the one or more pumping chambers to affect pumping of a production fluid therethrough the diaphragm pump.
