In this study, for the design of the impeller and volute casing shape of the water pump for flood prevention, performance was predicted through numerical analysis to secure the theoretical power and hydraulic efficiency of the front well at the discharge well 300m3/h, which is the target design specification, and the flow characteristics of each flow rate were checked and verified. Through the results of this flow analysis, it was possible to secure the basic shape design of the impeller and volute casing of the water pump for flood prevention. In the future, we will perform an interpretation to confirm structural safety according to shape and material.
