ABSTRACT OF THE DISCLOSURE A pump system is used to raise water to a higher level by using running water as the motive force. It includes a cham- ber that is slowly filled by the water, this raising a float and operating the piston of a pump through the linkage system. Once the pump piston has completed a stroke the chamber has to be emptied. This is effected by an overflow pipe through which the water flows and fills a container that opens a purge valve through a linkage system. In order that the valve remains open for a long period, but not permanently, there is a calibrated outlet in the container. The simple design of the pump system renders it suitable for use in developing countries.
