hyraulic splitter

[msukegrat]

I'm looking at 2 hydraulic spliters from Northern Tool. I have a Ex 3200 Cub with rear hook ups that suggests max pump capacity is 9.9 gal at 2600 rpm. I'm looking at a 20 ton spiltter that pump requires 11 GPM Max. The other is a 13 ton that requires 3 GPM max. I don't want to be dissapointed with the 13 ton but want to make sure the 20 will work.

IMO 13 ton is not enough... the 20 will work with your 9.9 but just a little slower

...also, the 13 ton only has an 18" stroke...

The GPM's just determines the splitting speed. The pressure determines the force.

I think your 9.9 gpm is both pumps combined . means naught except for marketing. Looks like 5.5 gpm off the main pump.

You can always make a regen circuit for under light load pressure, that would speed your time getting to the wood. You would probably want to add a pressure guage also.

the papers on my tractor tell me it's a 5.6 gpm implement pump, and i'm using it to power a 3.5x18 cylinder i used to make a homemade splitter. for me, it works great. one of my stoves won't take wood much over 18" anyways, so i cut everything to 16 +/-. knowing that a bigger diameter cylinder woudl slow the cycle time drastically, i went to the 3.5" and for a 1 man operation, i think it works pretty well. as far as splitting force, i assume the following is true, but i dunno. someone please correct me if i'm wrong.

for a 3.5 cylinder: splitting force = pi*r^2*pressure = 3.14159*(1.75*1.75)*2500psi = 12 ton +/-

for a 4 cylinder: splitting force = pi*r^2*pressure = 3.14159*(2*2)*2500psi = 16 ton +/-

i've seen all these new splitters out there advertising 34 ton splitting force, or whatever... growing up we used an old 4x24 splitter and it did everything we could put on it. i'm not altogether sold on these big power ratings. where i am, there's precious little hardwood over 24" that gets split for firewood. i know we split stuff that size on it.

I just picked up a Speeco 22 ton from TSC, I bought the hoses and I am installing the connectors.
