Default Brewhemoth Chiller pump

I am wondering what pumps are recommended for a Brewhemoth chiller? The Chiller is 1/4" stainless so the back pressure is pretty high. I plan to use a bucket of water in my refrigerator and some type of submersible pump. Does anyone have experience with this? I don't want to go out and buy a pump to find out it wont work so I would like to rely on the experience of someone who has it figured out already.

I think I would use some kind of march pump. They are made to run continously in hvac applications. Obviously does not have to be high temp so you could probably get one cheap off of ebay. Only negative would be the priming issue.

It's OOS right now, but my LHBS (in Canada) sells the same one. Made by ShurFlo, not sure what the model number is. It's a diaphragm pump, and unlike the March pumps, it's self-priming, which makes it much more ideal for transferring cool wort.

Default Brewhemoth chiller pump

I ordered this from Norther Tool-NorthStar 12 Volt On-Demand Diaphragm Pump - 1 GPM @ 40 PSI

My fingers are crossed as my only concern would be that it could potentially take 40 PSI to push the water through the small line. I plan to us a Ranco with a 120v in 12v out converter.

Can those pumps take the heat? I saw several say 130F was the max temperature.

You will have to worry about cold - not heat. Hopefully your fermenting wort will not be above 70F. This cooling fluid will never be in contact with the wort. Personally, for this application I would would use a centrifugal pump. That coil will have a fairly high resistance.

I use one of the little submersible pond pumps from Northern Tool on both of mine, they have worked great for 4 batches now. I use 15 gal of water in a chest freezer i cool to 34 and can get 1 brewhemoth to 50 for lagers and the other to 64 at the same time.

To 50 degrees without insulating the brewhemoth? At what ambient temps?

I have mine jacketed in water heater insulation all the way around but haven't run the chiller yet and I'm wondering what temp range I can expect.
