Default HLT Stirring

I am currently building a HLT with a sanke keg. I will soon put in a HEX coil and was wondering what works best for stirring the HLT.

I have seen quite a few are using a gear motor/paddle but I would rather keep everthing out of the cover if possible.

So, I think I would rather use a pump to stir. Anyone have a suggestion for a pump they have used or if there is a reason not to do it this way?

Thanks

Stirring with an external pump will cause more heat loss, but it is effective. Make sure the return is under the liquid level.

I currently stir using the pump, it does loose a lot of heat that way, but works. I am thinking of switching to some sort of paddle stirer, or air bubbler (in the HLT)

So is the pump itself or the plumbing loosing the heat. Could it be insulated? My HLT is electric. 4500W element. What kind of pump are you using?

My plan is to solder on (2) ss half couplings for in and out and put a dedicated pump right on the HLT between the couplings.

Heat losses are through the tubing, a bit, but I know my ss ball valve and fittings get very hot which means heat loss.

Anyone tried a submerged pump to mix or will the heat be an issue for them?

I am about to put together my HLT and was planning on putting in a whirlpool like inlet to stir it to. I am going to use this as my HERMS heat exchanger too, and heat loss would be a bad thing for that?

What would everyone recommend to stir it then?

I do have an old Ice Cream Maker motor that I was going to use for something (Mash stirrer?). Maybe this would be a better idea?

Thanks

Here is what I was planning to use for a pump:



Circulator Pump, Open Loop, 1/150 HP, 1 Phase, Voltage 115, 0.30 Amps, Inlet/Outlet 1/2 In Sweat, Housing Material Brass, Max. Temp. 230 F, Max. Working Pressure 150 PSI, Shut-Off 6 Ft., 3400 RPM, Impeller Material Noryl/Stainless Steel, Auto Thermal Protection, Warranty Length 2 Years

Like I mentioned earlier, I was thinking of mounting this to the HLT between the inlet and outlets. And maybe make some sort of directional outlet so It will whirlpool a bit. This pump is on sale for $62. What does everyone think?

Anyone know what Noryl is? Never heard of it.

Is that a food-safe pump? Most of us are using March or Little Giant pumps with magnetic drives, no chance of lubrication contamination... they are food safe.

I use my aquarium pump to stir my HLT. I just thread the hose through the end of my long spoon so that the output of the hose is at the bottom of the tun and turn it on. The air bubbles cause more than enough agitation to keep the water at consistent temps.
