4.2.6 Comments on table of lubricating oils for separators from Westfalia Separator
Faultless functioning of separators very much depends on the proper type of lubricating oil used, since a
high grade oil, selected to meet all service requirements, will minimize the wear, thus extending the ser-
vice life and increasing the operating safety.
For the lubrication of our separators we recommend to use the oils specified by us since continuous qual-
ity checks are performed by Westfalia Separator. Oils proposed from some firms are not subjected to
these tests.
Therefore, Westfalia Separator cannot give a performance guarantee for those oils.
Be sure to select only
high grade solvent refined products.
The specified oil types meet the requirements according to DIN. Under unfavourable operating condi-
tions, e.g. high temperatures, the quality of the oils may be insufficient so that more efficient oils, e.g.
synthetic oils, must be used. If necessary, consult Westfalia Separator.
For the different separator types and oil types the viscosity ranges are specified in the table of lubricating
oils.
The operating temperature of the separator exceeds normally 80
o
C (176
o
F). At those temperatures
some oils age quickly, so that they have to be changed prematurely.
Be sure not to use lubricating oils with viscosities lower than those specified in the table. Due to the pos-
sibility of the oil film breaking down, oil of too low a viscosity will give insufficient lubrication, resulting in
increased wear. However, oils with a slightly higher viscosity than specified may be used.
Bear in mind that the viscosity groups SAE 30, 40 and 50 (SAE =
S ociety of A utomotive E ngineers)
cover larger viscosity ranges and be sure to select lubricating oils with viscosities not lower than the
minimum values of the viscosity ranges restricted for the different separator types.
