Abstract Rotodynamic pump is a commercial machine and very used in the factories so the use of centrifugal pumps or rotodynamic pump operating as turbines or motor machine offers a technically and economically viable alternative to traditional turbines, the selection and implementation of a pump that functions as a turbine is a subject that is still under development. In this investigation the process of selection and implementation of the centrifugal pump is performed where centrifugal pump works in reverse mode, as a turbine, and mechanical adaptations are made for proper operation. The hydraulic system consists mainly of a forced pipe and a tank at a height of 13.3 m. In the built equipment a maximum efficiency of 58% was obtained at 890 rpm and an electric power of 45 W with a consistent load of a 120 V and 70 W bulb. The results obtained in this case study are comparable with the results of conventional turbines.
