Although now that I say that I just came across this that may work:

There are very few electric drum pumps that are rated for flammable materials for obvious reasons (electricity and flames don't mix).  In order to make them flammable proof they are made a lot more expensive and so we have never gone that route.  We have been using one of these for some time and, although manual, it does a great job and gets right down to the last dregs.

They do also have electric drum pumps at Uline but I would check to ensure compatibility with 95% ethanol

Hi all,
We buy our ethanol in 55 gallon drums at 95% concentration, which we then dilute down to 70~75% in smaller carboys. To transfer the ethanol we have thus far just been using a manual siphon pump, but are not totally satisfied with it.

The issue is that as we get below 25 gallons remaining, it becomes difficult for students to do the pumping (as the level in the drum approaches the level of the fill line in the carboys). Most of my students are not strong enough to lift the drums at ¼ to ½ full, so usually, I have to assist them when mixing the latter half of every drum. This is a huge time suck, so I'm looking for a better alternative.

Does anyone out there use an electric pump for 55 gallon drums? I see many options online on amazon etc, but a lot of them have poor reviews. Our ethanol storage room has outlets, so it doesn't need to be battery operated.

Best,
Nate
