A new positive displacement pump operating with a simple linear actuator as the prime mover has been designed, built and evaluated. The aim is to develop a pump that uses a photovoltaic power source and is suited to supplying water in rural areas of low-income countries. Previous schemes to raise water from boreholes with a photovoltaic power source have used sophisticated technology which can be a significant step beyond the previous experience of the communities being served. A configuration of linear actuator and pump has been chosen by seeking the simplest mechanism from the point of view of both operation and manufacture. Finite element analysis of the electromagnetic properties of the actuator is shown to be the best way to proceed in the design process. A very simple design with an actuator operating in a normal force configuration is shown to function effectively.
