Bottom line: With the replacement pump in and output pressures nominal and SEI Platforms Isolated, Pump Speed is within 7% of previous pump before it became impared.  This amounts to about 25 rpms; it is a different pump afterall.

The attached graph shows the four pump station pressures, the differential pressure across the BSC and the before/after control voltage. Not a lot of new data on this 3 day plot, but, I'd say the pressures, especially the differential pressure, are a little quieter now.  There is no indication on the monthly HEPI Pump's Famis task from Aug18 that this pump was ailing.

I judge this change a success but could everyone knock on wood, please?  Will update FRS and report separately on the removed pump after autopsy.
