We did our annual maintenance on our centrifuge about four months ago, and started seeing rising DO levels about two weeks ago. I tore into the machine, and, sure enough, the rotating seal was shot:
We replaced the seals at our annual, so we got a little less than four months from this $1,500 part.
It looks to me like the failure may have been due to heat. The ceramic mating surface of the seal appears to have spalled.
I don't think we ever run the centrifuge with this seal dry, but that's what the damage looked like.
Has anyone else seen this, and, if so, have you found a cause and a way to prevent this happening again?
