Live pump pessure rating

the pressure is controled by the relife valve in the powertrol box on the back of the tractor dont know the gpm but should be about the same as PTO pump live pump is smaller but turns twice as fast as pto pump
 
Kent, the aftermarket pump I have is a stand alone unit. It has its own tank and has nothing to do with the powertrol. I think that may be what he's talking about. So I'll come back with the same question of what the psi and gpm is on the JD live pump itself. Mine is a behlen steering assist, but is the same pump that is used in conjunction with the powertrol system.
I havent installed the behlen yet but would just like to know if you could shed some light on this.
Thanks a lot, Jim.
 
algar,

Like Kent said, the pressure is controlled by the relief valve in the Powr-Trol valve body.

Both the pressure and GPM vary depending on the tractor model and model/serial# of the Powr-Trol valve body.

What model tractor and model/serial# valve body are you working on?
 
To my knowledge the Behlen pump has no shut off,where the JD pump has a lever to engage it,so I think they are different pumps. Vaughn
 
I have a 48 A I don't have a live pump at the moment but I would like to know what they are capable of in psi and GPM.I thought they were all the same. I could run it seperate from the powertrol unit. Will it run a 45 loader as good as the pto pump? they were below 1000 psi
Iwas hoping for more out of the live pump
 
algar,
you can plumb your tractor to run the powertrol and your 45 loader separate without using a live hydraulic pump. I have one plumbed into the powertrol and use a back blade and a 45 loader for moving snow. Email if you would like more info. thanks, Jim.
 
A live pump on an A has a rated working pressure of 610 PSI and a GPM of 10.4 at zero pressure and 8.9 at rated working pressure. The two pumps are about the same.
If you run the live pump seperate from the powertrol unit you"ll need to add a reservoir and a control valve.
I think the live pump will run a 45 loader just as good as the pto pump AND you"ll be able to raise the loader when the clutch is disengaged.
