The aim of this paper is to introduce a systematic approach for the prediction of pump performance characteristics of different specific speeds when the experimental data are not available. To accomplish this task, a set of equations representing the best fits of the available experimental data is developed. The equations provide a data source useful in the design, simulation and checking of the pumps. The correlations obtained should avoid carrying out complex experimental programs in a test loop. Numerical results indicated that the proposed method favorably predicted the nuclear-grade coolant pump performance at minimal cost. Application of the method has demonstrated its viability as a tool of obtaining pump data useful to light water reactor safety analysis codes.
