Oil Transfer Pumps

[Grizzly]

Does anyone have a viable alternative to the old fashioned hand operated oil pump.
Having pumped yet another 20 ltr drum of oil into a system. I thought there has got to be a better way.
Electric would be good although limited by voltage and access to power (110v).
Better still has anyone managed to discover a cordless model.

These are nice oil pumps and filtering systems http://www.uspetrolon.com and they run on 110 volt

We have them in several of our facilitys.

nh3wizard.
Many thanks for your efforts. Maybe I should of used the word PORTABLE within my post.
To explain what I was hoping for.
Thanks Grizzly

Grizzly,

May be worth a look

Don't know flow rate or pressure range but may be worth a look.

Back on the power requirement again but is it possible for you to use your vacuum pump to suck the oil into the compressor/system?

[US Iceman]

Basically what you are looking for is a small single-phase motor driving an oil pump that will pump something like 1-3 gallons per minute. Just a little bitty thing that is very portable. Vilter has one you can order, or you could make one up yourself with some good hoses and hydraulic quick-connect fittings.

monkey spanners - Demon Tweeks option a little rich for me. ALTHOUGH some of our more enterpriseing recyclers out there may have a 12v option..
Any idea's Guys?
Brian. Yes and I do regularly use that method. But sometimes it's a simpler option just to "manually add the oil, say because of the power availability or cable routes etc.
Is there really only the ROBINET and YELLOW JACKET options out there?
Iceman. I was rather hopeing someone would come up with an option. Vilter is not a name I am farmiliar with. Does anyone know wether there is a U.K. Stockist?
I have used one supplied by a customer which had a Lamborgini motor / pump combination . Last time I saw one of those pumps it was on a hydrolic dock leveler pack.
Brilliant bit of kit though.
Maybe someone has made a similar rig?
Thanks Grizzly

Just had a thought Grizzly....

You can get 12/24vdc oil transfer pumps designed for engine oil change purposes.

This one here is designed for marine use hence the higher price but could be a starting point.

edit: A better link here for a range of pumps.

You might have to carry your own battery or get the van close to the work area

What I used to do when I changed a lot of oil (i.e. before I got in to "clean" A/C work) was to use reclaim cylinders. Not only is it easy on your arms but it will also keep the oil "fresh"/dry.

In the workshop, attach your vacc pump to the VAPOUR port of the reclaim cylinder, then a 1/4" line from the liquid port in to the oil can. Start the pump and suck the oil in.

After you filled the cylinder, let the vacc pump run for a while to get rid of any moisture.

Then charge it up with OFN.

When you get to site it's a simple matter of connecting up and open the valves, as long as the pressure in the cylinder is higher than the sump pressure it will go in (fast if the pressure difference is high).

WARNING:
If you decide to do this, check how much the cylinder weighs when it stops delivering oil and start to blow OFN, then have it on a set of scales when you charge your compressor. Unless you want non condensables in your system.

Great Link there Brian.
Thanks. I think Viking may have something there?
What about if I was to mesure the capacity of a small 2 port cylinder.
Using a vaccum pull say 80% volume of oil and then
precharge with refrigerant vapour.
Better still use the H.P. Standing pressure to push the oil into the low side sump. ( Now why didn't I think of that!!) Someone phone the patents office.
Does anyone see why we can't use a redundant cylinder and system pressure to push the oil in. If you follow that with some refrigerant so what.
Once the plant is running you can suc out the remnants of vapour down to suction pressure anyway.
What's everyone think?
A lot cheaper and less components to carry.
mk 2 what sort of pressure could you apply to a modern plastic oil drum?.. Just a thought although if you get it wrong, Quite scary and rather messy.
Seriously though has anyone come up with a practical method of oil transfer?

Grizzly,

I was serious, it's a method I used on more occasions than I can count.

The thing with OFN instead of refrigerant from the system is:
-What to do with the refrigerant after you got the oil in the system?
-you know that the OFN is clean and dry, if you use refrigerant, you might transfer accid/moisture on to the next system you work on.....

Grizzly, Vilter is a US manufacturer of industrial refrigeration equipment (compressors, etc). They have had this little oil charging pump for over 30 years, but it's not really anything special.

Have you ever seen a carbonator pump for carbonated drinking fountains? That is what it looks like.

Here are some comparable items...

Add a couple of good hydraulic hoses and some quick-connect fittings and you're done!

Iceman.
Thank you for the links nice bit of kit. You guys really know how to produce good equipment especially when it comes to specialised tools.
Viking.
Sorry didn't intend to "be-little" your option. I fact the more I think about it, the more using Nitrogen makes sence. Especially when using Synthetic Oils,
I believe some are capable of absorbing 10% of their volume in 24 hrs! (spoonfed)
( Keep the lids on tight guys)
Thanks.

ALso Grizzly you might pre-mix the oil if topping off the cylinder with refrigerant.

Not sure about the new oil/gas mixes but knowing the way oil and refrigerant froth up you wouldn't wont to start that process too early in the transfer procedure

Iceman,
I have looked in the vilter site and can not find the pump there. do you know where this can be ordered, I am in the US .

Thanks

Hi there,
I scored myself a redundant diesel transfer pump. I removed the motor, it has got a 1/2 inch shaft that fits nicely in the chuck of my cordless. It pumps easly against 400Kpa crankcase pressure. Just getting your hands on one might be the hardest part,
Good luck, from down under.

Iceman,

Yeah, they don't have their parts listing on-line.

Call the factory direct and ask for the parts dept. or contact a Vilter autourized contractor. You can find the firm closest to you here:

I have a good idea of what I need to make one up, going to tractor supply and grainger to check out what they have. I am doing new supermarket startups and spend about 12 hours pumping oil in all the racks. My arm thanks you.

You might shop for a carbonator pump used on soft drink fountains too. That should work nicely.
