I've ordered one, but it hasn't arrived yet. Wayne, do you know what
diameter drive pulley he used? I will need to know so that I can drive it
at the right RPM. HF doesn't say what the maximum RPM is. I have a 3450
RPM 15 amp, 230 V motor, but will get a 20 amp (5-hp) if necessary. It
would be nice if I can use the smaller motor I already have.

He reports that the sheaves are approximately 4.25 and 14.25 inches
OD. He can't find the paperwork that came with the pump, but says he
chose the motor sheave based on its recommendation. I heard the
compressor running, speed sounds about right, definitely didn't seem
slow, a little fast if anything (for what that's worth). Based on the
amperage, it seems like your 3 hp motor is similar to his so it should
be fine. Please report the details on your setup once it's running.
