H2O is known bad for non-plated ferrous components. Injectors (gasser) are known
to have problems with H2O, but don't know if diesel does too
But haven't heard anyone mention that, to toss the injectors as an issue with H20
The pump surfaces are DLC plated, but don't know if every last square inch is.
Does anyone know and then ask if there is any data on corrosion of those non-plated
areas/components within the pump?
Am trying to find the path the OEMs are hanging their hats on in regards to H2O
in the system
Corrosion is what am guessing they are referring to
Now the DLC and organic amines coming apart (another assumption that the OEMs
are saying) due to H20, but basically 'used' to know that diamond is very stable
and non-reactive.
Add organic amines, but no data that I'm aware of (dang, just have to find time
to read that article)
Add in cavitation, which I'm now leaning big time towards, as the accelerating
catalyst to all of this.
Then go back to a different type of pump that would NOT have such a high cavitation
potential. A gear pump would be my choice, but know that some sealed impeller
advertised PSI's in that range (very expensive and I have no other knowledge of
how well they live to their spec's).
Which then says there is a need to just replace the piston pump with
a gear pump with everything else the exact same to both remove the
piston as the culprit and/or say cavitation is the culprit
More later when have more time to noodle this...very intriguing !!!
