Absinthe Pete Posted September 17, 2011 Share Posted September 17, 2011 Here is the agitator I finally built. Came out awesome. Total cost less than $100. Although that's only possible because I have a full machine shop. 4 HP Air Motor Stainless Everything Explosion Proof Click on the links for the pics. http://www.raffdisti...gitatorsm01.jpg http://www.raffdisti...gitatorsm02.jpg You can also check out my website, just added some new pics and such. Also Like us on Facebook. P.S. The washer on the bottom are not staying on, just didn't have any Stainless ones on hand. Oh and it's tri-clover (sanitary fitting) which goes on a tri-clover ferrule on the still so it can be removed easily. Link to comment Share on other sites More sharing options...
Jedd Haas Posted September 17, 2011 Share Posted September 17, 2011 That looks great. Does it triclamp onto your still? How loud is the motor with that cute little muffler? Link to comment Share on other sites More sharing options...
PeteB Posted September 17, 2011 Share Posted September 17, 2011 Hi Carter, I remember you asking in an earlier post for suggestions for seals. What did you come up with? From the photo I am taking a guess that you used close fitting nylon for combined seal/bearing? Link to comment Share on other sites More sharing options...
bluestar Posted September 17, 2011 Share Posted September 17, 2011 What diameter is the triclamp? What would it cost to have one made up like it? Link to comment Share on other sites More sharing options...
Absinthe Pete Posted September 18, 2011 Author Share Posted September 18, 2011 Yes, it tri clamps to a 4" tri clover ferrule on the still. The motors a little loud, but not bad. PeteB, no it uses a real pump seal from Mcmaster Carr. It's a whole assembly you buy, comes with the seal and a spring for the correct tension. Remember this is not something that can be built without a full machine shop. Every single part had to be machined from a block of stainless steel. Bluestar, I'm not sure what it would cost as some of the parts I was able to find on ebay for cheap, but just the machining would be about $800. I could make the tri clover to the still any size also. Link to comment Share on other sites More sharing options...
Jedd Haas Posted September 18, 2011 Share Posted September 18, 2011 So the seal is in that short length of stainless tube between the triclamp and the motor and the shaft is post-seal? Can you post which McMC seal you used? Would also like to see a shot of the business end, did you make a part there or was that one of the ebay scores?

Absinthe Pete Posted September 18, 2011 Author Share Posted September 18, 2011 The dimension are the same as professional agitators. The tube is about 6" long and contains quite a few parts, lots of bearings, pump seal and motor to shaft coupling. http://www.mcmaster.com/#pump-seals/=e4ax3o The business end is just a standard Stainless Steel Agitator prop. You can find them all over the place, i didn't make it though. Link to comment Share on other sites More sharing options...
Jedd Haas Posted September 18, 2011 Share Posted September 18, 2011 Did you have to gear it down? What's the final RPM range? Can you show us the mechanism? Link to comment Share on other sites More sharing options...
Absinthe Pete Posted September 19, 2011 Author Share Posted September 19, 2011 No it's not geared down. It runs on air so basically you just turn open the valve up until it spins at the rpm you want. The motor says 300-3000 RPM, but since it's air just add enough air to get it turn the mass of your wash at 100 rpm. Sorry no pics of the mechanism.

So how has it been holding up for you, now that you've had about 5 months to work with it? I am looking for something that can mount on a 3" TC flange with about a 24" shaft. Are you interested in building one for me? PM with particulars, if you are. Link to comment Share on other sites More sharing options...
Absinthe Pete Posted February 15, 2012 Author Share Posted February 15, 2012 Sure, do you want it air powered? Can the prop be installed once it's mounted in the pot, it's either that or a folding prop. If it's air powered what kind of compressor do you have? What size diameter prop?
