If it's a front-mounted, crankshaft-driven pump, the "industry standard" is somewhere around a 13 GPM @ 2400 RPM pump for farm loaders, and 23 GPM @ 2400 RPM for industrial or HD loaders. Smaller pumps will work but the loaders will be very slow.
Keep in mind that the GPM rating means nothing unless expressed at a given RPM.
The only rating the means anything on its own is the cubic inch displacement per revolution.
Farm loaders usually have at least a 1.5 cubic inch pump. HD loaders at least a 2.4 cubic inch pump and loaders with backhoes 3 cubic inches at least.
My Ford 4000 loader has a 23 GPM. 2.6 c.i." My Deere 1010 loader has a 23 GPM. 2.6 c.i." My Deere 1020 loader has a 13 GPM. 1.4 c.i."(slow) My Deere 300 loader has a 24 GPM. 2.4 c.i." My IH 3414 loader has a 23 GPM. 2.6 c.i." MY Case 580CK loader has a 23 GPM. 2.6 c.i." My Oliver OC4 loader has a 23 GPM. 2.6 c.i." My IH B275 with loader has a 10 GPM (very slow). 1.4 c.i."
