Abstract

Centrifugal pumps are used to transport fluids by the conversion of rotational kinetic energy to the hydrodynamic energy of the fluid flow. Since it is the most used pump in the world, then it must be improved now and then. The rotational energy typically comes from an engine or electric motor. This study was performed to investigate the effects of changing the number of impeller blades in the Head and the Efficiency of the pump running at constant and varying speeds. The researchers were able to provide a pump performance curve for 4, 5, 6, and 7 blades running at 2300 RPM, 2800 RPM, and 3300 RPM. It is shown in the results that utilizing the researcher's centrifugal pump model with 7 impeller blades running at 3300 RPM is the most ideal and suitable operation.
