Hey All, I had an issue with a pump we were using to transfer and recirculate alcohol at 99%. The pump started to rust after a few days and ruined a lot of product. Does anyone have any good suggestions for pumps rated for High Proof Alcohol that are explosion proof and food grade. I would like to get around 50gpm. Thanks. 

My boss ordered this one

Hi Dan. Talk with @MichaelAtTCW they sell great diaphragm pumps that are simple to operate and safe to use with high proof. I use their pumps and love em

Thanks bud

Rust, eh? What kind of pump was it? What material was it made from?

We sell a line of groundable AODD pumps specifically for distilleries: SimpleSpirits Pumps.

These are air diaphragm pumps, so they require the use of an air compressor to function. The very rough rule of thumb with air diaphragm pumps is that you want your compressor to be capable of generating your desired flow rate in GPM x .75. So, if you want to pump 50 GPM, you need an air compressor capable of generating about 38 CFM at your desired PSI.

Alternatively you can get electric pumps with XP-rated components like this, but these get pricey very quickly.

I like the diaphragm pumps, thats our back up, but we arent set up with an outside air compressor yet so the noise is a factor and the filter manufacture we use says that the filters do best with a constant flow. The pump was an AMT 285E-X5

An observation, where do you get 99% alcohol from? 95.6% is as high as can be distilled at atmospheric pressure.

I would have thought at 99% there would be no free water and no rusting. Many big industrial continuous stills are built from steel and I assume they don't rust.

You should be able to carbon filter the rust from your "ruined product", but I am no expert on carbon filtering.

We use another process after it is distilled to remove the remaining water. It was actually 99.6%. I cant elaborate further due to a non disclosure agreement. We still have the 250 gallon with the rust that we will filter and re distill and then charcoal filter to be safe. We were using an AMT 285E-X5 which the guy swore it was food grade and all stainless steel. We should have done some more home work.
