I have been using a Little giant industrial pump 3E-12NYS in my test loop, and it is speced at 500GPH and 18' max head. I measure about 3.5GPM MAX out of that system. Not sure you are going to get 5GPM out of anything other than a positive displacement pump that is speced for 5GPM operation honestly. Even 3GPM is a stretch, especially using 1/2" hosebarbs (their ID is ~3/8). I have everything pretty much plumbed to 5/8" and need to finish up drilling out all those barbs even...
