There was another thread on this topic of oil changer pumps, but since this "new to me" used pump worked so well, thought I'd start a new thread. I am about to start to change my own engine oil and filters, so I was in the market for an oil change pump. I have been researching the Internet for suggested pumps, plus perusing the posts here on the HOF and looking for a unit to buy. I have been looking at stand alone units, and ER permanently installed units.
I found a used motor and pump unit out on ebay, which had an original application of pumping used cooking oil into 55 gal drums. The owner said he no longer needed it, so it was for sale. In the picture is was in very good shape. Well, I thought, if it will pump old nasty cooking oil, with who knows what it in, and fairly viscous, maybe it will pump used motor oil.
Technically it was/is a Baldor 3/4hp 110v "commercial motor" mated to an Oberdorfer duplex gear pump; it can also run on 240v if rewired inside the motor case, per a guide on the exerior. The pump duplex gears mate to each other while pumping. It was "buy it now" priced at about $150, and $200 with shipping, as it is 42#'s. What the heck, since a brand new Groco much smaller hp (0.1-0.2hp?) vane or gear pump is $250-$500 out on the net, I sprang for it. P.s, Oberdorfer pumps alone can run up to $1,200 on the Internet.
The motor came with bare wire ends, with commercial grade insulation. I had a good grade of 110v plug end, which I installed, carefully observing wire colors to ensure proper operation. When plugged in, it came to life instantly and ran without issue. I was careful to stay clear of the gears, which were exposed at the time.
The input/output was machined std. 3/4" threaded, so I bought a few fittings with different barb od's for the hose, and fitted a couple different sizes of hose for testing.
So long story short, I tried it out on an old gallon milk bottle of used motor oil I had sitting around, which was in the garage at ambient temp of 45-50 degrees. I pumped from the one full bottle into another, but empty, bottle. This might be cheating, but the oil might have been synthetic, so pumps easily when cold. 40wgt mineral may be a different story.
Wow! When started with 'dry' gears, with both the inlet and outlet hoses empty, and sucked immediately. It pumped the gallon in about 5 seconds, which surprised me, as that seemed pretty quick. The pump motor never broke a sweat- I never heard it bear down at all.
So for those looking for a first rate, high capacity oil change pump, eBay seems to have quite a few of these type of setups, around one a week, of motor/pump units, usually 1/4-1/2hp, maybe up to 3/4 hp like this one. They don't always indicate they are intended for motor oil, but they usually pump many other hydrocarbon or oil type products.
So for now, I am no longer intending to permanently install an oil changer multi-port oil pumper. My first in-the-field real world application should be this weekend. So I will report back on how it does on 26 qts/engine pumping! Also, I am guessing, I can reverse the input/output and use it to pump the new oil into the engines...maybe...we'll see.
That's my sitrep.
