woodsplitter running off front pump

Anonymous-0 · Jan 3, 2009

i have a mf-165 diesel with a freeman 4000 front end loader it runs off a 18 gpm front pump running off the crankshaft.my question is if i plummed it into my woodsplitter would it have enough umph to splitwood. THANKS RICK

Yes, should be plenty, of course the speed will depend on the size of the cylinder.

Yes. Two way barrel valves and two couplers would do it. JimN

Might actually be a bit fast. Adjust your throttle to slow down the speed if needed.

I've seen quick couplers on a pump that large actaully load the engine down when the valve is activated. That kind of volume can't get thru the small openings (check valves) on the quick couplers.

We had to take out the check valves to get our portable unit to operate correctly and never ran the power unit with the hoses disconnected after that. It did cure our problem.

To get full flow a typical Pioneer style will not work in a high flow situation. The poppet that seal off when disconnected is restrictive, but handy for swapping under power. For instance, when I installed my loader on my Farmall 504, I installed a fresh 17 GPM system pump and I used 3/4" Parker quick connects WITHOUT poppets, they are straight thru. If I need to remove the loader I unplug the 1/2" Pioneers. If I need to remove the 3 spool valve, I unplug the 3/4" couplers and can plug them into themselves to restore OEM plumbing. For the return hose I have a mating coupler with a plug in it to cap it off.

For 18 GPM, I would use 3/4" coupler poppet or not. should run the splitter fine even if fast. I do not see the problem with fast. Power is not a factor of fast. It is a factor of sq/in cylinder piston vs PSI.

Good luck.

Depends how big the pump is. The figure "18 GPM" has no meaning unless it has RPM along with it. A pump makes more gallonage depending on how fast it is turning. Cubic inch displacement is the figure that means someting without RPM.

If you have an 18 GPM pump rated at 2000 RPM, then yes, it's big enough to run a 4" to 5" hydraulic cylinder on a log splitter with a decent cycle time.

I"ve been dealing with a lot of hydraulic issues over the past couple of years with some projects I"ve been working on. One thing that I found out about is the "quick connect" issue. If using any kind of quick connect, it should be a size larger than your hose size. For instance, use a 3/4 inch quick connect on 1/2 inch lines. The quick connect reduces the amount of flow through a line, by going to the next size larger than your hose, you get back close to the original flow amount. Any restiction in a line causes heat and loss of flow volume. Some can"t be avoided, but some (like quick connects) can be remedied. Hope this little tidbit helps you out.

Good quick couplers have ratings for maximum flow and pressure. Buying larger couplers could be a big waste of money. Any hyd. system needs a large enough reservoir to help control heat. A front loader pump should work very well for a log splitter. Make sure you plumb it properly so you have a relief valve to prevent damage. Dave

It should work just fine. A standard 1/2" ISO coupler is rated to flow about 16 gpm give or take a bit.
We run a splitter all the time on similar systems. Works fine.
