The occurrence of cavitation due to suction recirculation is completely independent of the value of NPSHA. In other words, it occurs even when NPSHA is greater than NPSHR. Figure 5.29 shows the location of cavitation caused by suction recirculation which is on the impelling side (pressure side) of the vane near the vane inlet. This contrasts with low NPSHA cavitation, which originates on the suction side of the impeller vane, as shown in the figure.
