Abstract
Centrifugal pumps are essential in various industries in various parts of the world. Pump performance and electricity consumption are highly considered in the selection and use of centrifugal pumps, especially to meet industrial needs that do not comply with pump specifications. Impeller trimming is a method of reducing the size of the impeller diameter from its original size to maximize pump performance and efficiency. In this study, the pump performance was analyzed using an original impeller with a diameter of 130 mm and a trimming impeller with a diameter of 108 mm. The results of this study indicate that the use of impeller trimming with a diameter of 108 mm works according to the target operation, namely to produce a capacity of 2.5 m3/H at a head of 10 m so that it can increase pump efficiency by 29% and reduce electricity consumption by 33.387%.

Keywords
