PROBLEM TO BE SOLVED: To provide a liquid-driven feed pump that does not require electric equipment on a site where it is used and can mix a plurality of liquids, by utilizing energy generated when feeding a main liquid as an energy source in place of electric energy conventionally used for driving a motor of a pump. SOLUTION: The liquid-driven feed pump 1 includes an impeller rotation drive section 1A for rotatingly driving an impeller 2 by the liquid that is fed. The impeller rotation drive section 1A includes an impeller unit 2A equipped with the impeller 2 and a rotation unit 2B for transmitting rotational force of the impeller 2 to the outside by a magnet coupler means 5.
