Whats wrong with using 100% throttle when you need it? Diesels love to operate hi in their range. Actually, until loaded the "full throttle setting is just a hi rpm idle feeding just enuf fuel to keep the rpm at setting. This is the case even at lower settings. Wherever you set it, the governor in the fuel injector pump will try to keep it there by feeding more fuel [up to injector max] as load increases. It would probably be optimum to set an aux system up to be able to use about 95% of the full available HP. Since the HP curve is rather flat with a diesel, because torque rises for a while as rpm decreases, the aux system will not be able to stall the engine. [HP consumed by the pump goes down proportional to rpm and the engines HP does not .]

Larry I guess I just want to try to save it a little. For semi short tasks of
spinning it up to do a task I see no issue and indeed I step aside to your
better knowledge, ok, Pedal to Da' Metal it is then.
I have not given up, I betya I am missing something here, or I need to look
at it a lil different. Gosh it is screaming for something to do under there. I
mean physics can't be thwarted but there is a gimmic, a way, something I
have not found yet that would be stellar for usage of the
BX25's mid PTO I
bet. Heck this afternoon I looked at a hydraulic T-Post Fence driver and I
believe it consumed 5.3 G'sPM , If I created 6.86 GPM at 75% were in the
money for that tool, and that would be cool so...
Today I stopped into a very large Hydraulics repair shop in town called MD
Hydraulics. I talked my way into the hands of there seniormost repair
foreman, you know the guy, the one w/ a huge work area and a-hundred
pump bibles on shelves and long clean metal desks and hundreds and
pumps everywhere, tools and boxes and he had the best area in the whole
building, they rebuild HUGE stuff as well.
I told him my requirements and HP, I told him a long, not fat pump would be
desirable and if I could get inlets and outlets out the opposite end from the
shaft there would be bonus points so hoses could go straight to the front
w/o 90 degree fittings creating friction loss, and he says,
follow me. He
took me out back to an assembly others were building up, pointing to a
small most perfect sized Danfoss pump that looked absolutely perfect in
design and size. I wrote Danfoss and sure enough someone passed the
buck and I have yet to contact his asociates for they have no email, but I
will and I will attempt to ID and get it's specs and or ask for a pump to
match my givens with that configuration.
It's hard to do this from my seat, once these guys realize I am pumping
them for info and don't know what I want and they can't just ask for
for a model number and take my CC there not interested. I guess I can't
blame them, but if they found me a pump for a decent price I would be a
buyer. I need a spec sheet first, or a CAD file so I can chew on it and THAT
means they have to give up a model number w/o a sale, and in their minds
now I am off to price shop it...so it is hard.
FWIW
