The specs on the ones at Lowes' and HomeDepot's web site were either unavailable, unimpressive, or confusing (e.g. 0.1 horsepower, 0 head pressure, 115 volts, etc.) I found some available from Northern Tool and Grainger, however, that say they can achieve 50-55 ft of head:
What I need this for is basically filling up a few systems of copper tubes that range anywhere from 25 to 40 ft in height. I'm not sure if they'll ever get any taller than 40-50 ft, but I suppose if I ever have to do that, I can just plumb two in series.
Any thoughts on the drill pumps from NT and Grainger? Suggestions are welcome if anyone knows where to get better drill pumps (or something similar.)
PS: The drill pump will be powered by a Makita BHP452.
