Anyone quoting MTBF is either using statistical modelling (get X number of pumps for y amount of time, crunch numbers) or accelerated testing. Don't know what you would do for accelerated testing for a pump, but for something like a cpu, you do heat cycling and radiation acceleration along with voltage.
