Follow that link and the pages before and after to learn about high suction energy pumps.
One basic concept:
High suction energy impeller designs are so efficient at passing large volumes of fluid, that the NPSHr 3% values for those pumps do not mean the same thing as NPSHr 3% values for other pumps. By the time the NPSHr 3% value is reached in testing, large amounts of incipient cavitation are occurring inside the pump, sufficient to quickly damage the pump. Therefore, large margins of NPSHa over NPSHr are required to use these pumps successfully, you will see margins referenced from 5-20 times or more, NPSHa over NPSHr.
