The minimum HP would depend on what pressure you are going to run the pump at. If you are running the pump at the maximum 23 GPM at the maximum 2500 PSI, it would require 38 PTO HP. If you are running it at 23 GPM at 1500 PSI it would be 23 HP. You would figure 1 HP per GPM for every 1500 PSI. Anything below 38 HP would work with the pump.
