| Abstract: | The mechanism of instability of extra-low-specific speed high-speed inducer-centrifugalpumps is discussed and its control methods are presented. The experimental results of twopumps show that they can achieve very good stability by designing complex impeller andorifice plate upstream of inducer and main impeller. |
