I have a Dolphin 6000 AquaMaster pump (from about 15 years ago). It was offline for 7 of those years. It cost be over $600 and was a bear when I needed it to be. Noisy but powerful - practically a pool pump.
Basically it just died. I've replaced the diamond seal that's supposed to be lifetime once already and changed the capacitor once.
Given its power consumption of 1hp, I'm done and need a replacement. The problem is that I want to convert to a submersible pump, preferably DC but it needs to be capable very high head pressure and high flow.
I can't find the pump curve online any more since its discontinued, but here's the specs I believe I need to match: The dolphin consumes ~600W and was rated at a peak head of 29ft and a peak flow of 6000gph. Clearly, not at the same time.
I'd like to target the same peaks of 29ft and 6000gph but at a lower power consumption of <300W and lower price of <$300 in a submersible DC pump. That rules out the Reeflo Hammerhead/Barracuda, the Iwakis, and the BlueLines.
I don't think there's any chance of finding this.
So instead, I'm looking at using two pumps in series. The only combination that seems to add up is two Jebao DCT15000 in series. Peak head and flow is 4m = 13ft and 15000lph = 4000gph and consumes about 120W and costs $130.
So two in series should deliver 26ft max and 4000gph max at 240W and $260
That's short of the 29ft max and 6000 gph max but it's the closest without blowing the budget IMO.
What do you think? Is there a better solution?
