Oil pump idea

[Handyman]

I want to build or make some type of oil pump to transfer used oil thru a by pass filter from one container to another.

I've seen some oil pumps, but for several hundred dollars... Looking for ideas for a cheaper setup.

Any Idea's ?

I recently built what I call an oil "slurpee". It is a five-gallon Jeep can on a base with a 12V pump mounted to the base. I use it to slurp the oil out of the drain pans and pump it into the jeep can. When the jeep can is full it goes into the 55-gal barrel my neighbor has for his oil-burning shop heater. I bought the pump from SURPLUS CENTER in Nebraska. They have oodles of different kinds of oil transfer pumps; different voltages and different pressures. [img]/forums/images/icons/tongue.gif[/img]

Handyman,

Depends on how much work you want to do. There are manual pumps, but I suppose they could get pretty boring. [img]/forums/images/icons/smile.gif[/img]

If I'm understanding you, you want to transfer dirty oil from 1 drum to another, filtering it as you go. If cleanliness is critical, wouldn't a bypass pump be the wrong type? If the filter became clogged, a valve would open and dirty oil would bypass the filter and go directly into the clean drum. Am I thinking right?

Check out the Northern Tools catalog for ideas. Prices run from budget-friendly to downright hostile.

Dave I would be interested in how you built it ...

I was talking about taking used oil and pumping it thru a truck bypass filter as its transfered to another container

Thanks to the Northern tool idea... I think I have found what I have been looking for....

This pump piped

into this filter

then to a tank...

So how thick is the oil and how much of a hurry are you in?? There are a couple really low cost options. Gravity as in a syphon. It would help to elevate the source tank above the destination tank to get more head of pressure to help push it through a filter.

Idea 2: make the connecton to the receiving tank air tight and connect a shop vac to the drum's other bung by way of a heavy wall but clear tube. The vacuum on the receiving tank will pull the oil out of the supply tank and have enough suction to spare to pull it through a filter. You need a float switch to shut off the vac or not leave it unatended toward the end of the run.

Transfer pumps aren't cheap and wont vacuum up the shop. Spending the $ on a vac serves a couple needs.

OK, I guess I need to explain what I want to do...

I want to be able to change my oil in my semi truck, pump the oil thru a by pass filter (to clean the oil) and pump it into my fuel taks to mix in with the diesel...

We're talking 10 gals mixed in with 200 gals of fuel (might even mix in less over a longer period). Since diesel and oil will mix well... this will give me 10 gals of fuel every 6-8 weeks. It will eliminate me having to worry about disposing with the used oil... not to mention extra lub to the top end of the motor.

[img]/forums/images/icons/tongue.gif[/img] I have kind of been away from this thread for a while, but HERE IS THE ANSWER to what you want to do. Use the toilet paper filter setup to filter that oil. It's inexpensive and will remove EVERYTHING.....including any additive package that is in the oil. Back in da fifties, these filters were quite common, and I had them on several rigs, both gas and diesel. They will turn black diesel oil clear in about three hours of engine time. I have one on my tractor right now because it sat for years and needs a good cleanup. If you cannot find one to buy, I can send you a sketch that would show you how to make one. You could use a tiny gear pump to push the oil.....so what if it takes four hours. [img]/forums/images/icons/tongue.gif[/img] [img]/forums/images/icons/tongue.gif[/img] I have seen diesel trucks serviced with a van equipped with the oil filtering setup right in the van and the oil was pumped into the fuel tanks. They always had the trucks topped up on fuel when they did that, however, for dilution. [img]/forums/images/icons/crazy.gif[/img]

Handy; Guess I didn't know what a bypass filter was [img]/forums/images/icons/blush.gif[/img] . So using the bypass filter like YOU mentioned, would probably work. Have you come up with something yet? I'm interested in finding out more about what you're up to with this. [img]/forums/images/icons/grin.gif[/img]
