How many GPM are you looking at? And do you want the size of both pulleys, or do you already have one that you want to use, that you picked up at Harbor Freight?
I think 1750 rpm is the max I would want to run the pump.
I think that should give me about 6.6 gpm? Right?
It looks like I have a 4 1/2 inch motor pump and a 9 inch pulley pump.
I think that should put me right at around 1725-1750 with load.
Am I right at 6.6 gpm?
Theoretically I could push 2500 psi with a #8.5 nozzle at 6.6 gpm with that pulley combination and the 18 hp motor. Or am I off?
