Well I searched and came up with nothing so here is my question/idea.
Has anyone ever thought about or used vacuum to collect wvo/WMO or whatever it is you burn? I've been looking at pumps for collection purposes and I ran into a "super sucker" vacuum truck and that's where the idea came from, you tube has a bunch of vids with this method and it seems like the home built ones will empty a 55gal drum in 30-60 seconds if the setup is good. Is there a down side though to this method? I searched the ALT. Fuels section of SS and it doesn't look like anyone's attempted it? Just figured I'd ask because it seems like an effective,quick, and easy way to collect te fuels. Obviously you would need a tank strong enough to hold a vacuum but I'm thinking a big old propane tank would work.
Any input or comments on this idea?
Thanks
Tyler

Yes it will work fine. Thats how we collected wmo at one place I worked to run the furnace.

I've thought about that, using vacuum to suck oil from an engine/tranny. or I could use a small pump and air operated motor to turn the pump. The pump would have a small hose so it could be sent down the dipstick tubes on a cars engine/tranny/power steering.
ha ha ha haaa
SHTF I could go from car to car sucking oil. 6 miles to the gallon and about 3 gallons of oil per car that's 18 miles of travel per car.

I saw online people use vacuum pumps, that run of 12vdc or 120vac, harbor freight sells vacuum pumps although I'm not sure if it's the right type. A gentleman even went as far as using the vacuum line on his pickup to get vacuum in the tank and once it gets to a certain point ya stick your suction line in a barrel, open the valve and it'll suck te barrel dry.
It just seems to me to buy a good pump your going to invest some $ and you might have issues, as with the vacuum you will still invest $ but it seems as it would be a more forgiving system if you sucked up something you shouldnt. Like I said I am just brainstorming ways to make collection a little easier IMHO

Some of the oil change outfits use old propane cylinders that won't pass certification any longer (cheaper that way) and pull a vacume in it with the intake on a compressor.
You need a non-collapsible hose and they are generally thick and expensive.
You need a pump that is much more complicated than a 'pressure pump'
Viscosity will be a bigger factor.
Most vacuum pumps don't like 'stuff' going through them.
Pulling a 1 bar vacuum is more pressure on the container than 14psi of air (most drums are only rated for 10psi differential.
Unless by 'vacuum' you mean the typical diaphragm pumps that create a low pressure cavity (lower than atmospheric) fluid fills the void using the atmospheric pressure.
As vapor goes remember moving air creates static, static creates spark, sparks can make things go boom.
That said good grounding of drums and equipment is essential when working with even the less flammable liquids like used oil. You are never really sure of the mixture.
I use the Vac-Trucks you more than likely have seen. There are multiple versions out there from roots style blowers hooked to PTOs to simple diaphragm pumps. All have extensive explosion proofing. Matter of fact on one of my last jobs the operator informed me that he was told that when moving diesel now especially the low sulfur type to treat it just like gasoline. He informed me that a few terminals have had diesel vapor explosions. So don't take anything for granted please.
I would think if you can pull a vacuum on any vessel large enough in volume and have it so it will pull only fluid you could pre-charge your collecting containers. I use it when collecting air samples all the time. Its just alot harder to maintain that vacuum I carry four times the number of needed vessles when sampling because most are "shot" when I get to where I need to go.

A Super Sucker is something that I'll build one day. Just because they are neat. Our current pump fills a 55 in four minutes and twenty seconds. A SS will shave how much time off of that?
A SS has to be greater than 55 gal capacity to make sense. Please educate yourself with placarding your vehicle and other requirements associated with hauling WMO in container sizes larger than 55 gallons. It is a different ballgame hauling bulk.
Vacuum to collect ALT. Fuels
