A double volute casing is widely used to balance the radial thrust of centrifugal pumps, but the optimum volute configuration has not yet been determined. The purpose of this study is to search for the optimum design of a double volute, and several configurations have been investigated. Experiment using the double volute of two-dimensional shape has been performed to investigate the internal flow characteristics, and the changes of both pump overall performances and radial thrust due to the difference of volute configuration have been measured and discussed. The results showed that the best efficiency point of the double volute pump shifts to 90% design flow rate and the main reason of the performance drop by the double volute is attributed to the mixing loss at the volute outlet. The outer channel flow is not effective as the diffuser and the pump performance can be improved by changing the inner volute wall configuration. And the optimum design of a double volute is proposed.
