Resumo: With an increased demand for sustainable energy, the use of centrifugal pumps to meet the countrys water supply needs - by pumping facilities, the industry in general and agribusinesses - has been widely applied towards improving life conditions as well as industrial productivity. Brazil is a privileged country, by considering the size of the territory that needs water to generate wealth, in the different fields mentioned above. However, there are difficulties in handling this precious element, water, with regions where water is scarce, besides huge, dry and needy areas. For this reason, centrifugal pumps need to be improved to work better and with higher performance. In order to simulate the study, a basic Algorithm for sizing was developed and complemented with a more updated formulation from several references, by using information provided in manufacturers' catalogues so as to gather and match information that would certify the process. The study results (working under the same conditions) showed that in the rotor output diameter it is much more consistent and displays few alterations. Throughout the processing it could be greatly improved. With respect to width, it will benecessary to develop the rotor casting process so that better results can be reached. Last but not least, the obtained results demonstrated that through this methodology it is possible to develop a reliable Algorithm that allows studying the behavior and characteristics of new families ofcentrifugal pump rotors
