I don't know squat about "Overall Equipment Effectiveness". And I'm not a pump engineer (but I sit next to one).
But not knowing the subject never stopped me before. And indicators are a little bit of a hot button topic for me. So here's my two cents.
We sometimes try to track MTBF (for pumps and for seals), although defining failure gets tricky.
We sometimes track equipment availability (what fraction of the time is it available to do it's function, particularly important for standby equipment).
We sometimes track costs associated with maintenance of pumps, by pump grouping.
We of course track pump performance on critical pumps. This is primarily a tool to identify suspected degradation and help prioritize our refurbishment schedules.
We occasionally use Weibull techniques to try to characterize failure patterns.
I know some types of bean counters love to go a lot further with reliability and performance metrics.
is big on that. If you don't get answers here, you should go there (they have a forum there). I used to like that website for their technical content related primarily to vibration monitoring and other types of condition monitoring, but they were taken over by a beancounter who loves abstract beans that have no tangible relationship to my job (the type of stuff you're asking about in my estimation), so I've moved over to
for that info I consider more practical as a plant engineer involved in rotating equipment.
