Any experience with US Solar Pumps? Only $50.
 
Anyone have any experience with these US Solar Pumps. This 5 Watt one says it moves 2.2 GPM up to 4.5 ft and is only $50. Food safe and up to 100*C. Is there something that I'm missing here or is this a great deal?

I personally don't see anything wrong with it other than it being a 12v pump. It would probably be for a RIMS pump.

I have one of the ones linked here. It has stainless fittings instead of brass. I have it on my HLT to recirc and move strike and sparge water. I works well, very quiet, and much cheaper than another March pump.

I also have one of those. I have not used it yet since it has weird threads on it. But I did wrap it with teflon tape and screw on a camlock fitting. I was going to use it as a whirlpool pump or something similar.

Yeah I was thinking about eventually setting up a recirculating eBIAB system so this would be used to continuously pump the mash to maintain temperature. And maybe pump through a plate chiller at the end.

I also have the great brew eh pump it works fine but the BPS/NPT threads are actually BPS so NPT fittings don't really thread on fully they will be leak free but it just makes me a little shaky (these us solar pumps list the same threads) I would wait for great brew eh to get the new ones in with stainless true NPT threads

Well I just purchased 3 of the ss models from ussolarpumps.com for my new 15-20 gallon batch build after seeing this post. We will see how they perform but for the price it seems like it would be bad not to try them out. Basically 3 for the price of a march or chugger.

Those are pretty cheap pumps. Less than half the flow rate of a march 809 and about a third less head pressure. But, if you're not moving a huge amount of liquid and you don't have much veritcal lift, they would be economical alternatives.

The ones I bought say they can move 3gpm and max of 10 feet of head. I sure don't need to move 3gpm nor at 10 feet, probably like 2-3 ft. Hopefully they do what I need them to do. We will see...

I have one of the topsflow solar pumps. Works great to recirculate, with plate chiller, and for cleaning.
