What PTO pump for log spliiter?

[william127]

I'm considering putting a PTO pump on my 20 ton hydraulic splitter so I can run it on the tractor I already have. These pumps from flowfit look good value and there's lots of choice! From the spec sheets below what model would people recommended? I would like the splitter to run at a decent speed but still be able to split reasonably difficult timber and not rev the nuts off the tractor! If there's more information needed please ask me and hopefully one of you hydraulic gurus can help me out! Thanks!

first thing you need to do is calculate the volume of the cylinder in cc, then work out from PTO speed and gearbox ratio and this should calculate the cc of the pump required then that should tell you how long the cycle of the splitter will be, you may have to get a bigger cc pump to gain speed as you don,t want to be standing there waiting for ram to come down for long, but on this you may have to sacrifice a loss in power to gain speed, when i built my splitter it took a bit of working out with engine rpm and cc of pump per revolution,
