According to my calculation, I would need 1.5 HP (1.1 kW) to output 1 GPM @ 2,500 psi. I have a 1.7 HP & 36 in.-lbs. @ 3,000 RPM pneumatic motor (25% & 50% max RPM output 53 and 47 in.-lbs., respectively). Do you think this air motor paired with this 0.36 cu in pump could achieve that? Or would it be better paired with the 0.12 cu. in. (9-7763-B) or the 0.25 cu. in. (9-7766-B) instead?
A: With 1.7 Hp and 3000 rpm available as a driver, you could expect to see at best 1.19 gpm @2500 psi. Any pump would have to be no more than 0.10 cubic inch displacement or the power demand would either cause issues with the driver or limit the overall achievable pressure, among other possible failure points.

What size engine would I need?
A: That depends entirely upon what pressure you want to be able to generate continuously, what RPM you wish to run the engine at, and the GPM the pump will be putting out at that RPM. Please contact our Technical advisers for help with answering those questions.
