LUBRICANTS 

It will be readily understood how important ade-
quate lubrication is to high technology pumps like 
the Varian vacuum pumps. Correct use of appro-
priate lubricants makes a significant contribution to 
achieving best performance and warding off de-
fects. 
 
When handling lubricants, the following sanitary 
protection measures should be observed at all 
times: 

•

  Avoid prolonged, excessive or repeated con-

tact of the skin with products for lubrication, 
and also avoid directly inhaling the fumes or 
vapors of such products. 

•

  Protect the skin by wearing appropriate 

clothes and equipment (e.g. special suits, 
glasses or, where permitted by the safety 
regulations, gloves) or by applying a special 
protective product. 

•

Clean the skin carefully after contact with the 
lubricants by washing freely with water and 
soap. 

•

Apply a skin cream after washing. 

•

  Take off and change clothes or shoes on 

which oil has been spilled. 

•

Never put rags dripping with oil into the pock-
ets of your clothes. 

When disposing of waste lubricants, observe the 
following environment protection regulations: 

•

  The lubricants risk contaminating the water 

and the ground! Therefore never pour lubricat-
ing products on to the ground, into water or in 
the sewage system. All violations of these 
rules are liable to persecution as provided for 
by law. When using lubricants always keep an 
oil can nearby. 

•

  Take care in draining off waste oils. In dis-

posal of these products respect all regulations 
in force concerning waste oil disposal. 

The recommended lubricating oil is the Varian GP 
oil. The GP oil is a general purpose mechanical 
pump fluid specifically engineered to provide supe-
rior performance in high speed direct drive me-
chanical pumps. 

These precisely distilled fluids (100% solvent re-
fined neutral paraffinic oil) deliver lower base pres-
sure capability, faster pump-down cycles, and 
reduced maintenance requirements on both the 
pump and the fluid. 

It is absolutely necessary to continue using the lu-
bricants initially used to fill the tank. If this is not 
possible for organizational or business reasons, 
use only products with the same characteristics as 
the previous oils. 

Only use of lubricants of suitable quality will guar-
antee safe operation of the pumps. 

   CAUTION 

Mineral oils and the PFPE oil are incompatible. To 
change from one type to another, the pump must 
be stripped down completely and all parts washed 
carefully to eliminate all oil residues. 
 
If you expect to have to use other lubricants, first 
find out if the two products are compatible. In 
cases of doubt, the lubricant used up to that time 
must be flushed out by way of a pump flushing 
procedure. 
 

   CAUTION 

To avoid the risk of contaminating the oil, absolute 
cleanliness of the pump and surrounding area 
must be ensured during the lubrication proce-
dures.
