Hi guys, I've got all sorts of wild ideas for my next log splitter, I was just wondering what's the largest 2-stage pump you've seen? The biggest I've seen is a 28 GPM, just wondering if there's any bigger out there?
Moving oil isn't just moving oil!
It's about getting more work done with a much smaller engine.
wkpoor has a good point on the cost of the accessory equipment to have a balanced system. The double pump system is going to be spendy. The 1" plus dia. hose rated at 3000+ psi is going to be spendy also. Spool valve rated at 40gpm, more money.
The stuff costs a lot more because it is not as common. Most modern high pressure stuff is 1/4 or 3/8" line. You have to get to heavy equipment to see the high pressure high flow stuff. Here in Iowa the farm stores and auto parts stores only stock 2250 psi rated 3/4" hose. I have to go to a dealer to get the high pressure stuff. The 1/2 and 3/8" hose is rated for high pressure but the old farm equipment that takes 3/4" hose are not high pressure systems.
When you want to go big it gets expensive.

Check the dynex pump catalog... We have been running a 45 gpm variable displacement dynex for about 8 years now.
Our test stand it basically a mutant wood splitter, 120 inches of stroke of dual 10" cylinders..

If you can find cylinders to handle it, 60 gpm at 20K psi would make a hellova log splitter....
