I'm wondering where I find a two-stage hydraulic pump that can run at 3500 PSI. I see many log splitters advertised with such pumps - BUT - when I go to the actual companies that make the pumps - I can't find any rated over 3000 PSI. Barnes, MTE, Haldex, etc.
What's going on here? Are the sales ads bogus?
I'm asking because I want to build a 50 ton log-splitter that I can also use as a crawler track-press. I've seen it done and know it works with small tracks. I've seen some Deere 420 and 1010 tracks, as well as Oliver-Cletrag OC4 done in a HD 35 ton log-splitters.
My tractor mounted splitter has a 5" cylinder with a Prince PTO pump that only makes 2000 PSI. Fine for any wood I split, but technically it's only got 19 tons of force.
I want to build a splitter with a 6" cylinder and a 3500 PSI pump. That will give 49 tons of force.

A good friend and I were recently discussing our tractor electrical systems when he stated "I figure it all comes back to applying Ohms Law". At this point
