Thanks for the rule of thumb. So if I could correctly mount this pump on my JD 317 lawn tractor at 3000 rpm (could pulley it up for more rpm if beneficial) what would be the potential gpm (displacement) and psi be? What size hydraulic motor would match up to it?
A: These pumps are not meant for pulley drive. Doing so will greatly reduce the lifespan of the pump. At 3000 rpm this pump would put out 7.9 gpm, and with 17 Hp available on that unit you would be able to see, at best; 2300 psi if the engine were running at full throttle and power was not being used anywhere else. We don't have any specifications of what the intended rpm and power range for the hydraulic motor will be to begin to offer any suggestion as to what may work with those input values.

I have a crane that needs 8gpm @ 2200 psi. So if I run it at max speed will it want to run at max rated psi or will that be determined by the settings on the crane? The crane has an adjustment for pressure. So I am assuming if it's set at 2200psi then pump will accommodate that?
A: Any positive displacement pump will try to develop maximum pressure which will require a relief valve in the system to regulate. If you have an operating relief valve in the system it will control it.

I know the pump is driven CCW, but is that looking at the back of the pump (opposite side of the shaft)?
A: We define rotation as facing into the shaft.

Is it ok to use a belt drive with this pump? I want to use it on a small johnson loader (15 hp tractor). I believe the max psi is no greater than 600. Would run this one at 1800 rpm's.
A: These pumps are not rated for side load. They may work for a while, but their lifespan will be shortened.

What size gas engine will run this pump at 2500 psi?
A: This would require about 22 HP at 3600 rpm on a gas engine. A general rule of thumb is 1 hp per gallon at 1500 PSI with electric motors; with about 1.6 times that power needed for gas engine drive.
