Southeast MN | I used one of those pumps to transfer 10-34-0 one season and the pdf page info is about right, 2.5gpm. What kills them is the higher the pressure, the more amp draw, resulting in more heat. Definitely want the pump motor with cooling fins. Grainger has pretty good specs/info in their catalog.
Roller pumps and 28%: I've been running a hypro silver series for 6 or 7 years. Put new rolllers in it last season but probably didn't have too. A cast iron one may not last, never went that route so don't have any experience with them, other than it makes a cheap spare to have on the shelf if the good pump goes down, downtime will be about 20 minutes. | |
