82/140 Dual Stage Rotary Vane Pumps User Manual/ 87-900-937-01(L)
Only use of lubricants of suitable quality will guarantee 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 procedures.
