This paper presents an experimental study on the Cherepnov water lifter that can pump or lift water without the use of external energy such as electricity. The energy used by the lifter is derived from the potential energy of the water itself. The liffter consists of three interconnected tanks, one of which is open and two others are hermetically sealed. The water level and the pressure in each tank were measured to improve the undestanding of the behavior and the operational charateristics of the lifter. The effects of varying operating parameters such as the inflow rate, tank and pipe sizes, the relative positions of the tanks were analyzed. As a results, factors that can maximize the efficiency, shorten the cycle time and increase the delivery rate were identified.
