since you are putting out 8 bar I pretty much take it is a centrifugal pump and not a positive displacement pump. being a centrifugal pump I would THINK there is very little pump wear on your inside of your pump unless it has been pumping rocks or concrete. and it sounds like this pump is running fine except for a bit of air which won't hurt anything [might run a long time like that]. I also assume it has been a long time since it was new. even so I don't see to much internal wear. could be wrong. shaft seals and or suction.

I don't believe I would run it up much higher than what you are already running it at.
