The starvation theory could explain the diffuser and eye cavitation. Exceeding narrow band preferred operation could explain the inducer cavitation. Thanks for the inputs!
My plan of action is to setup alarms for the preferred operating range (90 to 105% of BEP flow), monitor trends over the...

Hi,
I have a Sundyne pump model LMV-311. Cavitation damage is evident on the inducer, between vanes at the impeller eye and on the diffuser bowl suction edge. The NPSH margin is 5m. The flow does at times exceed 105% of BEP flow.
Regarding a discussion held some years back...
