[chemi-cool]

Water in the oil.

Water in the oil.

[monkey spanners]

As above it's called emulsification.
Much the same as when a vehicle head gasket is on it's way out!
You get a milky white froth!
Has your Vacuum pump not got a Gas Ballast.
They are for removing the moisture from the oil.
Alternatively, time to change the oil!
Cheers Grizzly

Jon

could there be milk in it!!

[NoNickName]

Theres no water in the oil

Yes, there is, but you still didn't realise.

[monkey spanners]

Theres definately not enough moisture in the oil to cause problems, its done three vacs on this oil, it is due a oil change if the pump still works

[Brian_UK]

You've had an oil slug from a system hit the pump?

[mikeref]

Maybe a dye from a system mixing with vac oil? .. Brian UK, i've got garden slugs but don't have oil slugs that focus on vac pumps...only kidding.

[lawrence1]

I think Monkey Spanner's beer is still safe.

[r.bartlett]

It fell into a bulk milk tank..

[chemi-cool]

Well Jon,
You just have to send a sample from the oil to be analysed.

I will take a rain check on that pint, hope to cash it before Chistmas.....

[r.bartlett]

MS doesn't mention the oil..people are assuming it's to do with the oil..

A cow lactated over it..

[paul_h]

Rereading the OP, seems you're right. I'm backing you with your guesses of falling into a milk tank or a cow lactating over it!

[acnerd]

You've had an oil slug from a system hit the pump?

That's happened to me before, and it definitely turns the oil milky.

As far as water and vac pump oil is concerned, if you pour it out into a clear container, would they separate over time?

Not if it's synthetic!
If it's mineral based then maybe.

I had left my vac pump by the dairy door, i had stopped short of putting it back in the van due to the rain, was back up in the cake loft where the unit is sited and was just checking over the new compressor, climbed back down to see farmer and junior farmer using the slurry guzzler to suck all the gone off milk out of the tank. It had gone off due to the self repair function of all dairy refrigeration systems having failed to kick in, despite them running it for a day to be sure...

They had managed to cover the vac pump with milk, and fill up the plug too gave it a clean as best i could, tried it today and it vacs ok but doesn't smell to nice while doing it. I think i might have to take the motor off the pump to clean it proper as it ran down between the two

I think Richard and Ptsac got closest to the problem

If all your questions are this hard I am destined to stay dry!
And no I don't like Milk.

[chemi-cool]

At least we have learnt something new today

But still.... milk is 97% water......

[NoNickName]

Cow milk only 87%, but water nonetheless. Free beer deserved.

[chemi-cool]

Cow milk only 87% water .

Got it checked out:
0.7% - minerals
3.2% - protein
3.5% - fat
4.8% - carbohydrate
87.9% - water.

As I can see, the only ingredient that can make oil white is the water.

I never said the oil went milky, i just said the pump was milky, in fact the oil still looks a nice golden colour. Most of the milk seems to have gone over the motor, which now smells a bit of stale cooked milk.

Jon, that was a misleading question and considering it was put before the pannel of highly respected engineers/mechanics of R.E.(who sobered up for a shot at the prize),consider a contribution of goodwill to be suffice as payment for our services. In otherwords, 50,000 members(according to Chemi-Cool) will have their first on Jon's tab tonight. cheers.. mike

[lawrence1]

I don't think Jon will shout unless a shark bites him.....50,000 pints,,,big shout,,,,maybe it will take 2 sharks.

Close but no Cerveza?
