That's the one I have. Great pump. I am curious why you went with a 3/4 HP motor. Are you planning to run something else on that chord or just want to keep the third chord low amps and keep the size and weight down?
A 1.5 HP motor is the perfect match to that pump and will put out 1200 PSI for T&G and still run under 15 amps at full throttle. Do you know many amps the 3/4 HP motor uses?
What unloader you are going to use? I have had good success with the MV520 or even the MV540.
Looking foreword to see how your project turns out.
