After trying a few times and failing, and then finally getting shot in the face with veggie oil, i took pics and decided i needed help.
I bought this pump:
This 10 micron filter:
And this Racor:
Connected all of the hoses. Plugged in the pump and it would not pull the wvo. It worked for about 25 seconds, filled the racor up in the bowl, then stopped pulling the wvo up from the drum. Unplugged it, tried it again. Nothing. Pulls it up maybe a foot or so then just stops. So i tried connecting my hand pump. Same thing, just couldnt move the veggie. The hand pump works great when i am picking up oil at restaurants tho. So i just kept at it, then finally the hose i have shoved up the outlet of the hand pump flew out and sprayed my eyes with veggie oil. And it stings.
I've only tried this with cold (ie 65-70F) wvo, as my water heater element was broken when i tried to bend it. If i warm it up will it work? or is it a pump or racor issue? I'm thinking it is a pump issue.
Here are some photos of the set-up:
Im pumping up out of the drum. Tried lowering the whole thing to the floor but no luck. WVO is warm enough to pump, i live outside of philadelphia.
Anyone have any luck with this pump?
or do i need to spring for something more heavy duty
peaber, nice diagram
Im trying it the NO way. The drum is full of wvo and its plastic, so getting a hose in the bottom will be hard. Is there any way to do it the NO way? How about a drill pump?
A drill pump will work, they are slow and they don't prime very well but will eventually with hose manipulation. They wear out pretty fast but at $4 a pop doesn't really matter.
I think your wondering how to get the VO you currently have in there, out. If you only have bung holes (careful) to work with and you can't lift it, a drill pump is probably your best bet.
After you get the VO out....
You need some sort of bulk head fitting for the base of your barrel.
Or better yet, if your barrels are like mine, the bung hole caps have threads built in. Look very closely at the cap. If you cut out the center 3/4" out of the center your left with a 3/4" threaded hole (if your careful enough not to cut into the threads during this process).
Now, flip the barrel upside down and you can put a 3/4" pipe (black works best) in the threaded bung hole. Cut a hole in what was the bottom and is now the top.
If this sounds like something you wanna try let me know, I have more tips for you. If ya want I could post a picture too.
yeah id like to try this.
basically im flipping the drum upside down and using the holes as an outlet port to the pump? pics would be great
I got a stock oil pump from Autozone for a Chevy small block (1969 Nova with 350 engine) for about $15. They are nice gear pumps. Drilled out the intake & JB welded a several inch long piece of 3/8" dia black pipe into the hole. (Drilling was easy as the pump body is soft cast iron). Next drilled a new hole for an outlet & did the same thing. Plugged the original outlet with JB weld & also the bypass passage. Reassembled the four pieces of the pump with bearing grease on the shafts & gears. Shot some paint just to pretty it up. 5/8" garden hose slides right over the black pipe & gets a hose clamp to keep it in place. The pump shaft is 1/2" so it will chuck right up in a 1/2" electric drill (you can use a battery powered drill for collecting oil). I just emptied a collection barrel with 35-40 gallons of partially hydrogenated oil in about 10 minutes with a drill running at about 550 rpm. Higher rpm = faster pumping or hook it up to an electric motor at 1720 rpm. The pump is supposed to be self priming but it didn't pull the oil probably because the hose was into the heavy bottom layer of hydrogenated oil & it was about 55*F. I just used a funnel to pour some oil into the short pickup end of the hose to fill the hose & prime the pump, dropped the hose back in the barrel & pulled the trigger on the drill. Pumped the collection barrel dry no hassle. I've got two of these & they work great.
i posted this same discussion on infopop and got in touch with darryl who gave me instuctions on doing the SBC oil pump. sounds pretty easy and i will definetly give it a try.
Maybe you could get one of those priming bulbs that you squeeze, they look like a grenade? (Outboard engines usually have one)
Here is the whole set-up I have.
Barrel upside down, bungs carved out to leave 3/4" thread, black pipe used (suppose to not corrode after prolonged VO exposure). Right bung has 8 inch standpipe so as not to suck from bottom. Left bung very short pipe to drain settled stuff from bottom. Bare wire hot water heating element hangs inside top hole, bracketed so as not to touch bottom.
Get the 200 micron strainers from US Plastics. Cut your hole in the barrel so the strainer fits in it. See I cut it too big and had to line it with a sliced garden hose so the strainer wouldn't fall in. I also had an old strainer that I cut the old screen out of and caulked in some window screen. The double filter works good prior to going in the drum. Heat up for a couple hours then settle. When ready to pump, heat up again, then goes through the pump, then a 50 micron reusable/cleanable filter from mcmaster, then through two 5 micron whole house Omni filters, then into truck.
If I were to do it again, I would use a shorter stand pipe. The level in the picture where you see the VO level is where it stops at the top of the stand pipe. 6 or even 4 inches would probably work better.
