12v pumps

[REPO]

Has anyone tried the 12v pumps that I've seen listed on a few supplier sites? They are much cheaper than the quality 110v ones. Would the 12v be a good starter unit?

i was told buy it and think this is the only batch you are getting out of it.

That being said. I have no clue as i did not buy it

Can't directly answer your question but are the 12v pumps you are considering food grade and capable of handling high temps ( i.e. In excess of 212*F)?

The ones I have seen are rated as food safe, and good for 100 degrees C.

If they are the little tan ones, I would spend the couple dollars extra and get the 24v. I use a 12v for mash recirculating and it's just fine, but if you try to whirlpool or anything the extra power is beneficial.

I have this one. Its called "the little brown pump" around here. I used it for recirculating during the mash but found I got the same results without recirculating so I stopped. I'm just about to start using it for filtering beer. I haven't heard any negative feedback about it. I thought I read it will last 4 years running 24/7, doubtful but for $18 I have no complaints...A search for "liitle brown pump homebrew" may bring up some results

The nice thing about DC pumps is they usually have a lot more power than a similarly sized AC pump.

I have two of the "little brown pumps", got them on Amazon for $20 each. The only issue I've ever had with them is the 4 screws to attach them to whatever, the plastic broke fairly quickly so they are now "strapped down" with gorilla tape and my staple gun. I've had 200+ degree water/wort through them and had no problem. I used a couple of old 12v phone chargers to convert them to AC. They are both still going strong 6 months and many batches later. I take them apart every few batches to clean out the impellers and make sure nothing nasty is left in them.

That's great to hear! I was wondering if anyone had actually pumped hot wort with them.

Can you run both pumps on a single power supply?

These little pumps are great because they're submersible too. I have one for transferring wort and one that I throw into my water reservoir for chilling. That way I can Pump ice cold water through the immersion chiller instead of moderately cool tap water. I have a chugger which I think is a good product but the size of these make them more convenient for 5-10 gallons although, they are slower as to be expected. I screw one onto the NPT ball valve of my mash tun and priming is not an issue if the outlet is facing straight up. I have about 20 batches in on the one for my mash tun and its held up very well.

Also, this thread has probably all your questions answered.

I wouldn't recommend running them off one power supply. I use a surge protector with a switch and only plug in the one I'm currently using. I usually only need one for my batches unless I have to set up my IC as a heat exchanger.

I have looked on ebay and found these pumps:

Has anyone tried them? I want to use it for mash re-circulation in my BIAB process. I am just building the setup and I don't know if 2 g/minute will be sufficient.
