Hi Charlie,
We ship the pump out and have it rebuilt.  I'm unsure as to what precisely
they replace.
The pump eventually will shut itself off (or the ICP-RIE shuts it off) and
needs to be restarted.  Once this happens more frequently (i.e. either does
not restart or shuts off immediately after restart) we swap to another pump
and send the 1st out to be rebuilt.  It is several $1000s per rebuild.
-Bill

What part of the pump gets replaced on the rebuild?
What indicates when you have to do a rebuild?
