That pump is only good up to 160˚F. No good if you plan on pumping boiling wort. I also would be concerned that it is not a food grade pump. It has a shaft and shaft seal that would be exposed to the wort. The March pumps use a magnetic drive that has no shaft seal.
I would do a little more research before buying that pump for brewing.
There's someone on this forum who uses this same pump... Forgot who, but sure he'll chime in here. Says he's had good luck with it. Boiling wort is over the ratet temp, but its not like your pumping wort for 8 hours a day. For the price, it will work just fine. Just be sure to sanitize very well.
