What is the vapor pressure in oils?

​

This parameter is very important.

​

It is the Pressure / Temperature at which the oil begins to evaporate. For example, the vapor pressure of our Ultragrade UG19 oil is 1 x 10-6 Mbar. This means that this oil can be used in pumps that have a final pressure greater than this value. Double stage pumps normally reach a final pressure of 1 x 10-3 or -4 Mbar. Then this mentioned oil can be used without fear that it will evaporate inside the pumps described above. Consult one of our specialists to determine the right oil for your application.
