Maintenance for DRP-04

Wednesday, April 4, 2018
Full Rebuild
Equipment/Beam Line: 

This pump was given a full rebuild reusing the nearly new teflon seals that were installed in September 2017.  The bearings and seals were suspect.  There was a case leak.  Pump tested and reached 4 mTorr within a few minutes.


April 5th:  Pump run in for 24 hours.  The pump ultimately bottomed out the CG controller and ran at 50C temperature.
