Recommendation for a DC return pump

[mfinn]

Just curious as I am also looking to replace return pump. But why dc? What is the advantsge? I'm looking at a dcs pump also. Is the noise level comparable to a mag? It's in my bedroom so I too must think of noise

My main reason for going to a DC pump is lack of noise.
I replaced a Reeflo Dart with a Vectra L1. The difference was simply amazing. The Dart which was pretty new and fairly quiet as far as Reeflo pumps go, but when I hit the power on the Vectra, I could not tell the pump was working except for the air clearing out the the return lines and water flow.
Once I had the Vectra L1 running ( closed loop) I could now hear the Eheim 1262 that I was using for a return pump. And they are suppose to be one of the quieter ac pumps.
IMO mag pumps are very loud compared to a Eheim. So yes, most DC pumps are extremely quiet compared to a mag pump.

There are several advantages to a DC pump. Noise is probably primary, ability to adjust flow, less heat transfer to the tank (the old Mag 1200 I use to stir and pump NSW around with will heat a 60g drum of well temp water to nearly 80 f overnight). You'll hear folks talk about electrical usage... I'm not so convinced on that one. Most inexpensive ac/dc transformers are not particularly efficient. Might be less than an AC pump, but it's not enough for me to worry about.

My eFlux DC return pump is virtually silent, and has been dead reliable for the 8 months I've had it. Price was right, flow is what I wanted, so far, I've got no complaints.

I cringe with the added heat but the rest of DC pros i dont find as a plus. Like quiet have a tunze ac pump and cant hear it run, been running for 5 yrs and just replaced impellar. Maybe in a few yrs when someone gives a run time will consder but 8 months for $200 plus pump not ready for wild card. But i live in Az and may roll the dice if i could get a 1-2 degree temp drop

For me head pressure was my issue and wanting an internal pump, I went with the Current Eflux 3170. Was the only internal that could provide enough turnover at 12 ft of HP. Vectra, R.O. and Jebao all fell very short. I didn't want a DC pump pushing at maximum just to get the flow either.
