vacuum pump oil problems

Hi friends, I have a little problem. I have a new vacuum pump I had not used it is 2 stages. But when it started to make everything perfect empty I left 10 minutes I turned it off and did not close the keys of the manonetro and the oil I think of the vacuum pump the compressor absorbed it when it was in low pressures and empty is that possible? Since seeing the indicator is missing a little oil to the pump and in the eye of wey of the manonetro as it is taking oil since I see something viscous and white. Does the pump extract that oil again? or is it not possible that it has been introduced to the compressor? Why not close the keys and the yellow absorbed by the blue because there are low pressures in the empty bone compressor and how I did not close the key of the manonetro. Is there a problem that this oil is in the compressor bone vacuum oil? thanks i'm new using the pump

Hi Alirio, it is normal that if the pump is two-stage and you had not used it, this oil is shared between both stations, if it is kept below the level, below the middle of the sight glass, you should take that level of oil to half or 3/4 of the viewfinder. For the rest it is impossible, that the oil, escape to the compressor or vice versa, that oil in the hoses, are residues of other works. Luck. S @ lu2 friovega63.

What happens is that I throw almost all the oil jar that brings the pump from the factory and almost reached the top bone and I turned it on empty I forgot to close the keys and then I see that it is missing oil .. .
and I thought that since the refrigerator compressor is empty it has absorbed oil from the pump. How do you say that is impossible? so do not close the keys of the manonetro ?.
The pump is finished pouring all the jar of oil that it brings from the factory, very little is really left but I throw it out and now it is in the middle of the viewfinder.
Be anxious because it is the first time I use a bomb

When the first oil is made to the double-station pump, a time must be set for the pump to work and share that oil between stages, then the level of being necessary is completed, perhaps as if it was enough once, now all at once. left at home, nothing to do with a transfer of oil from the pump to the compressor of the equipment, that is impossible, I would have to have the hose an absorbent stick, to drink oil Coca-Cola mode.

Ok thanks for the answer I had that concern since it is my first time to use the pump. (Y)

In order for the vacuum of a system to lift an oil column from the pump to the equipment system itself, the vacuum pump should have the hose connections below the oil level, an illogical thing already thought by the manufacturers of vacuum pumps, which always place those sockets on the upper end of the pump itself so that something like this never happens. Another illogical way would be for you to make a system empty by entertaining yourself, laying the pump to one side with the gauges obviously open.

Thank you for the communication. S @ lu2 friovega63.

If thanks for the idea or notion that you have given me, it is logical that the oil is not absorbed because the hose or some connection is not really touching the oil of the pump and cannot return or absorb it due to something that is empty.
Only it is my first time and as I saw something viscous white in the eye of wey of the manonetro I got scared and asked the question that I already solved by his comments :)
