The Exair Reversible Drum Vac might better be described as a “liquid transfer pump,” since it can fill or empty a 55-gallon drum in about 90 seconds.  It runs on compressed air and has no moving parts, and it attaches to the bunghole of any 30 or 55-gallon closed-head drum.  And you can stop giggling — “bunghole” is the correct term for the opening in a drum.

A check valve automatically shuts the system off when the drum is full.  Since it runs on air power, you don’t have to worry about electric shock or about setting fire to hazardous materials.  This would work great for cleaning up liquid spills or emptying a sump.

In vacuum mode it performs the same function as a shop vac, except that a shop vac can’t empty itself, while the Drum Vac can pump liquid into another container just as quickly as it sucks it up.  Also, you can adjust the flow rate and dispense fluids with the Drum Vac.  Stainless steel construction ensures a long service life with all types of fluids.

For the average home shop or garage, this tool probably won’t see much use; but it could come in handy in machine shops for emptying coolant tanks, or on construction sites where sumps fill with water. Street pricing starts at $370, and Exair’s MSRP is $600 — a bit more than your average shop vac, but it also does a bit more than your average shop vac.

    we had a pump at the motorcycle shop that worked like this- you hooked an air line up to it and screwed it into the bunghole (… okay, lol) and it bulged the tank out a bit and used positive pressure to move the luquid (used motor oil, in our case) out of the barrel. worked a treat to pump 55-gallon barrels out into the big tank for the used-oil heater.

    We have one of these in our machine shop, yonks old and hand built, similar to that one except the top comes off to empty it. Trouble is it spends its life hoovering up swarf, there’s so much room that when it comes time to empty it its too heavy to lift up without two of you!

    I need to fill Lake Titicaca with crappuccino. If I connect this to my bunghole, will I be able to locate the T.P.?

    Are you threatening me?

    Sound advice, but here’s an extra pointer: Do it carefully; do not anger the bunghole. You do not want to face the wrath of the bunghole.

    I knew this cat in college who used to order pizza and give the name “Byoong-holly,” spelled B-U-N-G-H-O-L-E.

  8. James says:

    If anyone comes near my bunghole with a vacuum or a hose for that matter, we’re gonna have a problem.

    No suction around the bung hole.
