I used to work in the ultra-high vacuum field.
We used turbo-molecular pumps that were essentially built like a jet engine powered by an electric motor.
The systems we used them in required a mechanical fore pump in order to draw enough atmosphere from the system to not mangle the pump if it took on atmospheric pressured air.
A standard system we commonly built and used were pumped to 5 to the -10 power torr for the work to be done. It was imperative to mech pump a system to 3 to the -10 torr before starting a turbo pump so it didn't get trashed.
Shut down required killing the turbo pump that was already running in a pretty clean vacuum,so there was very little resistance to stop one.
A normal shutdown took about 20 minutes for the pump to unspool to expose it to atmospheric pressure.
One test I performed required a minimum of one hour of pumping and shutdown time per operation. With assembly and disassembly added to the mix,I could only test 6 items per shift when adding the one hour airlock time for entering the class 10 clean room I did them in.
One day, a super salesman brought my outfit a new in box sample turbo pump he said was guaranteed to not be harmed by venting a chamber while it was shut down but still spooled up.
A week later,I had to call him back to tell him to pick up his junked out $5000 sample.
Never tell me that something you have is indestructible if you don't want to see it destroyed,to me,that's just a dare
