We had MS turbo pump failure and I would like to share what we saw and what we did to fix it.


After shutting down the MS for a month, we had MS turbopump speed problem. The turbopump speed did not go above 20%.

Here is the video of the turbopump


We called Agilent support and they told us some tips and troubleshooting. I will list that as a flowchart as following.


We end up replacing the Agilent turbopump with Pfeiffer HiPace 300H turbopump (This was suggested by Agilent support team).




I hope you never get this problem, but if you did, I hope it helped!
