Help making an auto to industrial oil selection

[Jeff_in_VABch]

Hey guys, I could use some help finding an automotive grade oil that will replace a mfg. supplied industrial oil which is very expensive. The oil Im trying to replace is $371 per 5 gallons and I need 10 gallons.

The oil is a sealing fluid for oil sealed liquidring vacuum pump system. These pump systems are capable of using water as the sealing fluid, so the oil does not affect wear.

Specs of the oil per mfg.:
-highly refined, hydrotreated dewaxed parrafinic oil
-low evaporation loss

Vis @ 40C ASTM D445 21.5
Vis @ 100C 4.25
VI ASTM D22270 100
Density 7.1
Pour point F/C -40/-40
Flash point F/C ASTM D92 440/226
Specific gravity ASTM D1298 0.853

Any ideas?

This is very light weight stuff. It appears similar in weight to 0w-5 racing oils. Red Line has a 5wt racing oil that doesn't seem too far off. This is way beyond my technical knowledge, so I'd send them an email asking about it. They have a good engineer that responds to technical questions.

How much does the thing cost you are filling with oil, it takes 10 gallons so its large to huge.

If it costs several thousand dollars I would find an oil that exactly matched their requirements rather than some oil that Jack the ace mechanic said should do.

This fluid has similar viscosity to a light ATF fluid. Alas, ATF is unlikely to be any cheaper than the original fluid. In addition, ATF has EP additives which your pump may not need/want.

I think I will try Redline. Their synthetics are pretty low evaporation, and that is pretty important.

Low cold viscosity is also important as the pump has very large drag on a cold weather, cold start, and can be prone to not starting if it's really cold. However in typical operation it runs 24/7 at about 150 to 200F oil temp depending on ambient air temps the oil cooling system injests.

Lately is has ocassionally pulled slugs of water/junk into it's resevoir and Im not spending $18 a quart on oil that may only last 3 weeks. Is any oil really worth $18 a quart? Not likely.

Some power steering fluids may also have similar specs.

Very low volume costs a lot to produce and ship.

With a really expensive piece of equipment, I'd be inclined to go with the really expensive oil.
Going cheaper on an expensive piece if the spec lube gives good results may not be wise.

 

[dubie2003]

Look into Mil Spec fluids. Something along the lines of 5606, 83282, 87257, 7808, etc.... Search for hydraulic and see what options come up.

 

[Quattro Pete]

I agree with fdcg27. Who's going to pay the bill if the expensive machinery happens to fail and incorrect fluid is to blame?

I don't know what brand you're using now, but if you choose to stick with the proper stuff, check XOM and RP Industrial and see what each offers and in what sizes and prices. For some stuff, XOM winds hands down. For other applications, RP Industrial offers more convenient sizing and prices.

If the pump can actually use water in place of the oil, why aren't you using water?

Most pump oils have very, very low volatility -- much lower than water.

Have you contacted Lubrication Engineers yet?

I work for an oil distributor, and much of our business is industrial lubricants. A good portion of our industrial sales are our house-brand products, many of which we blend ourselves. We have or can make equivalents to most name brand products.We are located in the metro Detroit area, but regulary ship to customers out of state and our price may still be considerably less even with shipping. Ill print out and bring in the specs and see if we can find an equivalent. It sounds like an expensive piece of equipment and I wouldnt recommend playing guessing games as to which fluid might work. If theres any other info you can provide, it would be helpfull such as the specific brand name/product name you are using now.

The oil is a sealing fluid for oil sealed liquidring vacuum pump system.

ISO 22 oil for sealed liquid ring vacuum pump does not have detergent.

Why don't you call the refinery where you worked ?

I would be inclined to go with a premium PAO/ester based air compressor oil. These have strong anti-oxidant properties with no detergents, dispersants, VI Improvers, metals, or ash.

A fine example is the Lubriplate Syn Lube 22:
