Hydraulic log splitter pump

[chuck diesel]

I have a 18hp briggs on my log splitter with a 22gpm pump. Its a waste of gas. I think it would be best to have the biggest single cylinder engine you can find. 16hp would be fine.
Plus if you have 28gpm pump your valve most likely a 25gpm so right there you are building heat in the system. i hope you have 3/4" hoses.
When upgrade your pump you should upgrade your hydro. tank. Rule of thumb: the tank should be the same size as your pump out put. The cooler the oil is the longer the life is of your pump. Good luck

arboristsite.com has all you will ever need as for splitter ???'s. You will find most of your info under the firewood section.

As long as you meet the HP requirements of the pump, They will get the job done. A larger engine will gain nothing, as the pressure and GPM have been met. All of the two stage pumps have the same pressure ratings. The 28 GPM has the largest displacement of the group of two stage log splitters, and only needs 12 HP to run it. Either add another tank to fulfill the 28 GPM requirement. or install a 28 GPM tank

When you have a round that is like this many times the splitter 'cuts' it's way through the whole length of the wood. Rounds like this do not "split"! We have come across a few chunks that take a lot of repositioning before the wood will split even with the 30 ton setup I have.

If you positioned the piece so that the wedge goes through a big crack instead of solid wood, it would split much easier. I used to do pieces this size and bigger by hand. Had a Go-Devil, sledge, and 2 wedges.

I have yet to see a log splitter with even half as big a tank as the pump has GPM.

You are probably right, due to the log splitter is not used in a constant mode. The engineers have been slowly dropping the tank size, mainly for mobile applications. I believe a one to one GPM ratio is used for mobile systems. I still think the large plants that use hydraulics, use 3 times the pump volume for the tank size. As long as the operating temperature is kept with in about 180 to 220 degrees, it should be safe enough and give some longevity to the hydraulics system.

A system with gravity load, lika a chip trailer hoist, will need more tank volume. Because of heat generated when throttling down load.....100% energy go to heat in valves...that might be what generated this custom ...."3 times the pump flow"....
