Default How many RPM's is too much for HLT Stirrer

I am looking at buying components for a HLT Stirrer for my HERMS and I stumbled across a 129 RPM CW Rotation 14 lb-in Torque Geared motor that I would like to purchase. It that too high of RPM's? I am going to put a left handed pitch 4" aluminum prop on the end. I have a 15 gal converted Keggle.

I'd say something between 20 to 50 RPM's is all you'd need. All you want to do is cause the water to move not vortex.

If it's DC you can run it on lower voltage.

I use one of these on another project, and it has some serious torque at 12V.

I would like to stay AC if possible to keep it simple and that way I don't have to find another 12v adapter. I have used all of them in the house for other DIY projects and would have to go to RadioShack for a new one.

I know The Pol recommends 100rpm min. I bought a 220rpm gearmotor and it seems to be ok (still don't have a finalized setup, just testing). It depends on the stirrer blade as well though if it will work.

Depends on how far out the paddle blades stick. The outside diameter plus rpm will determine the speed to some extent. If you think the motor is a good buy then just adjust the paddle would be my suggestion.

should be fine. 2x a second is not all that fast.

Are you using a copper coil in your HLT to recirc your wort through or are you using a CFC/heat exchanger?

As long at it's not throwing water out of the HLT you should be good.
