I built this for gathering my WVO. I gathered the information for this on other forums. It is not my idea just sharing the info I found on the web.

This can suck up a 55gal. drum of WVO @ 50deg. in less than a minute. Starting with a 22" vacuum and ending with about 15". I also read that it can do very thick stuff in the winter. Did my first drum Sat. Much better than my 12v pump.

It is a 100gal propane tank. I welded a 2" nipple on the bottom and a 3/4" nipple on top. Add 2" ball valve to the bottom and reduced the top to (2) 1/2" ball valves ( vacuum and pressure sides ). Reduced the 2" to 1 1/2" and added cam lock couplers and 25' suction house and a wand w/ ball valve. Some where in there I built the stand to have 1" tilt forward to help drain.

This can be used to suck up just about any fluid and could use any size tank.

Hope someone can use this info.

Where are you getting the vacuum to power it?

 

I bought a Thomas 12v vacuum pump.

 

Add extra piping and valving so you can use the pump to pressurize the tank. That is what we did on our 250 gallon propane tank. Keith

 

I am going to do that once I mount the pump to the tank. Right know I'm just using a compressor.
