Abstract
All discussions about cavitation in centrifugal pumps lead to one firm conclusion: cavitation is a direct result of an available net positive suction head (NPSH) that is too low. This implies that when the available NPSH is lowered, the intensity of cavitation increases and that an increase in the available NPSH reduces the intensity of cavitation. However, there are cases in which the opposite appears to be true. In these cases, the pump developed intense cavitation when the level of the liquid in the suction tank was very high. As that level was lowered, the noise was reduced. Finally, when the liquid neared its lowest level, cavitation disappeared completely.
