6 to 8 gpm is plenty.  If you have too much volume, then the loader will react too fast.  But if using pulley & belt to drive the pump, the ratio can be changed if needed.  Pressure can depend on cylinder bores.  I have 2" lift cylinders, and I'm only running around 800 to 900psi (pressure relief setting) and it will lift more than is safe.  If running smaller cylinders, it will take more pressure to raise the same load.  1500psi is well beyond what you would need.

THIS pump is basically identical to the pump I am using on my Massey 1655 with FEL.  Mine is off a Case 446, and I am running belt to drive it.  Some pumps can't handle side loads on the shafts, but mine is holding up well after quite a few years of heavy use.  I am running a 5/8 belt, so I don't have to have it real tight, so it doesn't load the shaft as much.

Also, when you look for a spool valve, be sure it has an adjustable relief valve built in.

Sounds like a nice project and I'm lookoing forward to seeing it. And it might be nice to get a valve with a float position on one spool.

That will be a fun project. You will learn a lot about hydraulics when you have it finished.

From experience I have found that having a pump larger than needed is not a good thing. The more oil you flow the more heat you generate and heat is not a hydraulic systems friend. You can however control the flow by changing the rpm of the pump. Rule of thumb provided by a hydraulics vendor, pump flow per minute should not exceed reservoir capacity.

 Good luck with your project.

Great point!  I have a pump with a max flow of 10 or so gpm, BUT, I have it reduced with pulleys about 3 to 2, then I usually only run a bit over 2200rpm.  So likely I'm not pushing 3 to 4gpm if that much.
