Does anyone know how many amps each one of these pumps draws?

On the instructions I received it says min start-up power consumption less than 2 watts. Also that it's rated at 12VDC

That's .167 amps or 167 milliamps.

It's a soft start. Max draw is 15 watts for the fastest (3GPM) model.

So I grabbed a phone charger or some kind of power source from Savers the other day on a whim while not really thinking about it. It's output is 12VAC, 1.25A. I don't know much if anything about electronics but the pump is 12VDC so does that mean I need a DC source? Don't want to mess anything up trying to power up this little guy

Yes. Do not use that 12VAC power supply.

Alright, after another trip to Savers I found another charger/power supply/whatever it was, checked to make sure it was 12VDC, spent another whopping $1.99 and then came home to wire it up. I wasn't sure what the best way to go about this was so I cut the tip off the charger stripped the wires at staggered lengths, crimped them together with some butt splices and then wrapped it in heat shrink to help seal everything up. I tested it and it works fine. Didn't bother to see how many gallons per minute but it was moving fast enough for my purposes. All in all not bad. And now I don't have to lift my pot of boiling wort to gravity feed through a chiller and can recirculate through my BIAB stovetop batches.

I've used these pumps for 2 batches now, and here's my experience.

My stand uses 2 pumps (one from greatbreweh & one from us solar). One recirculates hot and cold water through my CFC for heating the mash & chilling, and the other is used for mash recirculation, wort transfer, and whirlpool chilling.

For whirl pooling, I wish it had more power so that I could get a better trub cone. I may try stirring with a sanitized spoon after everything is chilled to see if its really a lack of power in the pump or if it's just the way my kettle is shaped.

I've found that the pump that handles wort needs regular disassembly and cleaning. I'll figure out what it is that is getting stuck in the pump head next time I clean it, since I haven't cleaned it between circulating the mash & circulating for whirlpool. I don't think grain husks can make it through my mash tun screen, so I suspect its expanded bits from pellet hops.

I've tried cleaning these in place by recirculating hot PBW through them, but it wasn't enough to clear the stuck debris. I'll look at the plumbing in my system to see if can be configured to back flush one pump using the other.

For anyone with a march pump, do you find that disassembling the pump head for cleaning is a needed chore?

I have one of these pumps. If you want it to work well, you need a 2 amp 12V power supply (for the one that does 3 gpm, the one that works the best).

I tried with a solar panel that does supposedly 18 watts(a little lower than 1.5 amps), but reality is it doesn't get the pump going full bore.

You can buy the 2 amp 12V power supply on ebay for about $10 or so. Or you can use an old PC power supply if you don't care about wasting energy and having a big, ugly beast near your brewing station. They typically have lots of amps at 12V.

Get one of these http://bit.ly/1eHd4EI

Mount it in your control panel and use lighted toggle switches to turn your pumps on and off. It makes it look so much cooler.
