The pipe size really doesn't drive pump size. But if you have a spa or water volume water feature, that could. If you have neither, then get the smallest pump possible and save on energy costs. Those two pumps are fairly large and probably way more than what you need. At least go for the smaller Harris (1 HP) although that is probably more than you need too.

A two speed though costs more up front but would save more on energy costs down the road.
