My return pump is on its last breath after a major disaster this weekend and will be dead in a day or two. I need to replace it with another pump that runs in the 4-5000 gph range. I had a Dolphin Aqua Sea 5200. I could go with that, but Champion Supply has a Dolphin Aqua Sea 5600 that does 6400 gph at only 3.3 amps versus my 8.9 amps on the 5200. The 5600 is not a pressure pump, but does that really matter for my return pump on about 8' head. The 5200 is a pressure pump, but I have to throttle it way back.
Which one should I use? Speed is of the essence as I have to get it overnighted to me. They cost about the same.
