I am using the 1/20hp, 120volt, one phase, 60 cycle (197 watts), 20lbs of thrust (17,000gph), 1500rpm, A&O Smith motor. This pump runs my gravity feed system (no head) and I will use a Sequence 1000 to run my Bakki.
You know, there is a whole thread about this over at the Mudpond. Hopefully its ok to post a link to that, if not, JNORTH can edit this for me and let me know:
