JD Hydraulic Flow Pump

Looking for a hydraulic flow pump like this one in the picture. My 316 has this tiller setup already.

Does anyone know if a pump like this could be used to power a wood splitter?

Any input would be greatly appreciated.

NOT sure exactly what you mean by a "hydraulic flow pump", what you have is a gear-type hydraulic pump.

I have a tiller just like yours I have mounted on a Ford New Holland diesel garden tractor.

The Operator's Manual gives the flow and pressure info for that pump, but mine is at the shop. I will try to remember to grab it tomorrow, and post back. (ASSUMING you don't have one?)

NOT sure what you want to do, re-purpose the setup you have, or buy a similar pump?

If you want a similar pump, Surplus Center has a good selection.

You will need to know the rotation, GPM you want and how fast the pump will be turning to find a pump with similar capacity.
Gear pumps

The pump you choose must fit the task at hand. For example, if you want to power a hydraulic cylinder for a wood splitter, then you must begin with figuring out the internal volume of that cylinder. The inside diameter of the cylinder plus the length of the stroke of the rod will tell you how much oil is needed to make the rod go from being fully retracted to fully extended.

Once you know the diameter of the piston inside the cylinder, then you can calculate the area of the piston in square inches. This is needed so that the relief valve in the hydraulic system is set to a specific pressure that will allow the piston to exert X number of tons of force on the log being split.

Most modern splitters do not use a pump like the type used to power that tiller. They use a two-stage pump that will put out a very large volume of oil at a low pressure so as to make the cylinder retract quickly once the splitting stroke is completed and will also move the log against the splitting axe quickly. Once the pressure builds to a pre-set point, the pump automatically switches to the low volume side to complete the splitting stroke. This saves an immense amount of time.

The pump in the photo has a pulley on it that is designed to be powered by the PTO pulley on the engine via a V-belt. If you intend to power the pump with a pulley, then you need a special pump that has a roller or needle bearing at the front of the pump to handle the side-loading that a V-belt places on the pump. Most gear pumps do not have that type of bearing. Instead, the aluminum pump housing is bored to size and the housing acts as the bearing to support the shaft. These types of pumps utilize a "pump adapter" mount that bolts directly to the rear of a horizontal or vertical engine so that the crank output shaft can rotate the pump via a simple jaw type coupler such as ones made by Lovejoy.

Aside from the actual pump, you will need a hydraulic reservoir tank, a cartridge filter housing and filter, hoses and a control valve that is designed for the log splitting industry. As mentioned, pretty much all of this can be had from Surplus Centre once you do the math and figure out exactly what you need.
