 note = {application/pdf, As the performance characteristics of a very low specific-speed centrifugal pump are much different from those of a normal specific-speed pump, there is strong demand of full understanding for the internal flow of the very low specific-speed centrifugal pump in order to improve the pump performance. The purpose of this study is to establish a method of visualization by PIV for a very low specific-speed centrifugal pump and to make clear the internal flow characteristics of the pump. Test pump has specific-speed of ns=100[m,m3/min,rpm] and 150 in combination with two types of impellers and two types of volutes. The result shows that vortices and reverse flows in the impeller passage cause a drop of theoretical head at partial flow rate.},
