Arrg - this is what happens when you dont read the entire thread.Sure, but he was talking about attaching a pump to his crankshaft splines. That's why i assumed the pump would operate at crankshaft rpms. But it's entirely possible that something about that statement was a misunderstanding because a 5gpm @ 1000 rpm pump would stall a b7001 at 1000rpm if any load were placed on the hydraulics, and once revved up would probably make the loader very jerky/fast moving to the point i think a lot of people would complain about it. At this rate we'll never know what the truth was unless he gets an email notification and decides to pop back in.
A 5 GPM @1000 RPM fixed displacement pump would be roughly 1.3 CID and you would need about 6HP to drive it @2000 PSI. Crank it up to 2000 RPM and 10 GPM and @2000 PSI you are sinking about 11.8 HP.
That would be a real load on a 16HP B7100 but it should run it without stalling. I have hung several pumps that size and even a bit larger on a 22 HP L-head. Those customers are typically looking to run a loader and/or log splitter. and I have two on the schedule right now. No problem with engine power but its the max displacement I recommend because the sump on those tractors only holds 5 gallons and with prolonged operation at 1500-2000 RPM aeration starts to become a concern.
