I want to build up several gear pumps for pumping oil. I figure that
getting steering pumps from an auto junk yard will be the cheapest route.

I wonder what vehicle may have the highest flow pump. Should I just
consider that the larger the vehicle, the faster the flow rate?

Thanks

Actually, translate that just a bit from "largest" to "heaviest".

Heavy vehicles normally require large steering forces for the large (lots
of contact area) tires they have to twist to and fro.

But you might be surprised at the 3600rpm output of a simple passenger
car pump.

Volume and pressure you expect pump at would be a fairly useful set of
parameters to specify. Likely even vital.

Get one from an older Chevy/GMC V8 Diesel. The pump has to run
everything, including the power brakes. There is no vacuum on the
Diesel.
