live hydraulics question

My question is is it possible to do live hydraulics with a seperate hydraulic tank and not go off the tractor sump? If i go off my front mount pump to my loader valve then from the loader valve to my adjustable priority flow divider, the adjustable port at 2-3 gpm down to my test port and the over flow port back to my seperate tank. Is there any reason this wont work? Thanks for your knowledge and imput.
 
Read an old post and see now why this wont work. From my understanding what goes into the test port gets returned to the tractor sump. Correct me if im wrong.

That is correct. If your external pump is not pulling it's oil supply from the tractor sump you would very quickly pump the contents of the external tank into the tractor and wind up with an empty tank and an overfull sump.

Guess the only way it would work is if you could pull out of the tractor sump the same amount that is being put back in by the test port.

That is correct.

If all you are doing is live hydraulics that is not a problem. Just hook the pump suction line to the drain on the bottom of the internal pump, the pressure line to the test port, and you are good to go.

If you are trying to do more (e.g. higher volume remotes with a larger pump or dual purposing a loader pump that has it's own reservoir) you have to get "creative". You can use an external reservoir to [u:351ca7eab5][b:351ca7eab5]augment[/b:351ca7eab5][/u:351ca7eab5] the internal sump but you cannot entirely eliminate the tractor sump. The tricky part when doing that is maintaining the correct fluid levels in the two different reservoirs.

If you told us exactly what you are trying to do perhaps someone could offer more specific help :idea:

ok I have a paulson front end loader I want to be able to run it, live hydraulics and a set of remotes. I'd like to run my splitter off the remotes.
 
(quoted from post at 14:00:57 01/03/17) reason I wanted a separate tank was to simplify plumbing.

All it does is complicate the plumbing. You can do what you want using just the internal sump and one suction line. The suction side is the simple one - the pressure and return side plumbing is not.
