Brand new, Prince SP25 series, special non-symetrical gears give higher efficiency than conventional pumps. Aluminum body. Ideal replacement for many brands on tractors, other implements. SPECIFICATIONS
A: The HP required is dependent on the flow rate (GPM) and pressure (PSI). A good rule of thumb is 1 hp per gallon at 1500 PSI. As an example if you turn this pump 2000 RPM it will move 11 GPM. Operating at 3000 PSI would require roughly 22 HP.
