how to cheap transfer pump? - larsalan - 09-15-2012
Any idea how to make a 12v/dc or 110v/ac transfer pump that can push through a filter?
How about a submersible pump plumbed into a filter is that good?
RE: how to cheap transfer pump? - JustPassinThru - 09-15-2012
Well, I'm not sure if this is what you're asking, but...in my WVO refinery setup, I'm using a 110-VAC 7-amp carbonator motor, driving a Procon pump, which pushes (already hot-centrifuged) cold vegetable oil through two filters in series; the first is a Whirlpool household water filter with a 5-micron element (bought at Loew's), and the second is a Goldenrod 15-micron water-block fuel filter (bought from Dutton-Lainson). I have a liquid-filled pressure gauge before the first filter.
When the filter elements are fresh, the oil gets pushed through at 20 psi, unless the air temperature is below 45 Fahrenheit, in which case it's 40-50 psi. When the pressure hits 100 psi, that's how much the Whirlpool is rated for, and I figure it's time then to change both filter elements.
This motor+pump has no trouble at all reaching 200 psi, to the centrifuge, if I let it (i.e., if I fully close the bypass valve).
A cheaper way, might be to rig a clothes dryer motor via pulleys-and-a-belt to a power steering pump.
Hope this helps...

In case the above is unclear, here's a pic. Pressure gauge, Whirlpool filter, Goldenrod filter, and then a Dramm valve. And then into my 5-gallon mixing bucket it goes, through clear PVC tubing. All piping is galvanized steel, all joints sealed with Teflon paste. If you duplicate this arrangement, *make very sure* that the Dramm valve is open before you start the motor!!! (--unless you are a terrorist, in which case you want to close the Dramm valve, start the motor, and then run like hell muahahahaha....)
Am I even close, to addressing what you intended to ask?

Just need something to pump the fuel. I wonder where I can find one. I thing that sump pump maybe the ticket.

You mean, at the fuel tank, just to supplement the lift pump? --like, a Mister Gasket 12S

I seen that same one at amazon.com for like $35.
I need to pump it out of a barrel through a filter and into the car's tank.

Ah, now I see (I think). You're looking for one of these hand-cranked barrel pumps then. No idea where to get one, or how much they cost; I bought 35 gallons of kerosene on Craigslist, and the seller threw the hand-pump in for free, along with the barrel. Perhaps at Harbor Freight or the like. A home water filter such as the Whirlpool would be easy to plumb into the spout. It will produce the necessary 20 psi of pressure, easy.

That's what I have but it is super hard to pump through a filter.
Then if you want the electric version of the barrel pump you're looking at a couple of ben franklins.
RE: how to cheap transfer pump? - JustPassinThru - 09-16-2012
The one I have would have no problem pumping through a filter. Perhaps yours needs disassembly and cleaning.
Alternatively...electric-drill-powered fuel pumps do exist; here's the one sold by Diesel Secret Energy for $29.99. It's pretty weak though, you'll need a strong drill of at least 2000 rpm to make it useful.
Of course, you could always take eight feet of any kind of hose and siphon it into a 1-1/2 gallon Brita pitcher from a thrift store, then pour it through an 80-mesh eight-dollar Oneida food strainer screen from WalMart into your tank through a funnel. Your pickup screen and fuel filters will take care of anything that misses.
RE: how to cheap transfer pump? - larsalan - 09-16-2012
well the barrel pump can move oil fine. Till you attach a filter, then it's a bitch. I think them little drill pumps are probably a bit tinker toy.
RE: how to cheap transfer pump? - JustPassinThru - 09-16-2012
Hmm. My barrel pump really *gushes*! I don't doubt it could push 20 psi. If yours isn't gummed-up inside, then perhaps mine has lower gearing than yours. It's Weyerhaeuser surplus.
I guess you'll have to go the siphon-and-pitcher route then. Perhaps using coffee filters a-quart-at-a-time. Unless you can figure out a way to use engine-vacuum-pump vacuum to pull from the barrel through a filter into a catch-jug. A science project.
Late here, beddy-bye time. G'night. Hope someone else can come up with a better solution.
I was just nodding off when the thought occurred to me: is it veggie oil you are trying to pump out of the barrel?
Zzzzzzzz....
