The net positive suction (NPSH) is an important factor because the value of the available net positive suction head should not drop below the value of the required net positive suction head. If that happens, the absolute pressure of the liquid at the inlet of the pump will be lower than the vapor pressure of the liquid at the given temperature. In that case, cavitation will occur.
