Cavitation??
Mind the following information given in the report:
"The manufacturer assessed both pumps as still being capable
of delivering full fuel flow."
Yes, that's right, and what is your point exactly? A scuffed wall of a car tyre does not alter its stopping distance. A pump that shows evidence of caviatation does not particularily alter its performance, and would still allow full fuel flow. They are both evidence of what has happened.
HOWEVER, a pump that is undergoing caviation at the time however is severely suffering in performance.
Would I buy a centrifugal pump that had suffered cavitation? Yes, no problem, (within limits) the key is not to drive the pump so that cavitation occurs.
