Greg brings up a good point that supplements and/or bolsters the non-plated
metal innards of the HPFP, that is then oxided by H2O, that then has particles
dislodged by cavitation events, that then become debris to be plowed into high
PSI areas, that then gouge DLC, that then allows extremely high PSI areas to go
metal on metal (both debris plowed/gouged DLC) and cavitational removed lube at
that very extremely high PSI spot.
Failure would be in just a few more PRMs...
On that, what is the micro size of the filters protecting this HPFP?
Then ask what is the min micron sized particle it would take to
plow/gouge the DLC?
Then ask what is the oxide particle size of debris dislodged inside
the pump, after the protective filters?
Oh...another question...does anyone know what/how organic amines
do to bare metal? Add in H2O. Add some heat and maybe some high PSI...
All exposed in some combo to cavitation...
It always, to me, says to either reduce the PSI (larger dia cam/follower
or widen the cam face/follower face)...or toss the piston pump for a
gear pump.
