This is the second report of study on dynamic behaviors of a pump system by using Bondgraphs method. In this paper, the more detailed model of the system bondgraphs on the dynamic behaviors has been established considering the influence of an impeller configuration and internal losses of the pump. Especially, the mathematical expressions of nonlinear internal losses of the pump are derived and their effects have been investigated. It is known from this research that in high speed transients the impeller configuration affects the dynamic behaviors greatly. And the internal losses become important in low speed transients. Also, through this study, the effectiveness of Bondgraphs method to the transients analysis for turbomachinery system is proved.
