The stability analysis with utilizing the lumped parameter piping system was performed in the double-suction centrifugal pump. Cavitation surge was observed in the region of the negative gradients of suction performance curve at low cavitation numbers. The cavitation compliance K and mass flow gain factor M, which represents the dynamic characteristics of cavitation, were evaluated by combining the stability analysis with the several experimental data. The values of K and M were distributed near the analytical neutrally stable lines. Both the experimental and analytical results show that the higher flow rate produce the narrower region of cavitation surge. These results indicate that the analytical results agree with experimental ones qualitatively, and the analysis proposed here is available and the K and M are reasonably estimated.
