Vacuum pump oil and grease

Diverse options
  • Mineral oils for pumping air, noble gases and chemically non-aggressive vapours
  • Mineral oils with additives for an improved chemical stability in aggressive conditions
  • Paraffin-based oils also for chemically aggressive vapours
  • Synthetic oils for aggressive conditions and good thermal stability
  • Perfluoropolyether oils (PFPE) approved for use with oxygen and the most aggressive media such as fluorine
We recycle used materials. Wir recyclen gebrauchte Materialen.

The requirements of vacuum coating are very different, e.g. pressures of up to 10-8 mbar are required. Oil-sealed vacuum pumps are also required, among other things. The respective pressure ranges required for the different coating processes can only be set with special oils. In addition, the vacuum oil used must have an adequate inertness with the process gases.

With us, you will receive the container sizes which are adapted precisely to your needs. We take PFPE oils back for recycling.

Oil analyses

As an additional service, we also analyse used oils for our customers. Here, typical wear metals such as aluminium, lead, chrome, iron, copper, are determined quantitatively in ppm. We also analyse solid and liquid impurities in ppm or weight/% or vol%, such as dust, moisture, soot. Finally, the degree of oxidation and the viscosity of the oil are determined and, if possible, compared with the fresh oil. The results are commented upon and a recommendation is voiced.

The purpose of the oil analysis:

  • optimised maintenance intervals thanks to the occasional testing of oil from the aggregate and comparison with fresh oil. This allows us to determine the optimal maintenance / oil change interval.
  • Breakdown inspection with analysis allows errors to be isolated or ruled out


  • Required sample quantity: approx. 100 ml
  • Analysable products: all types of oil for vacuum pumps, provided they are not toxic or irradiated.
  • Time requirement: calculated from receipt of the sample, maximum 2 weeks until the results of the analysis come out.

Pump maintenance and repair

  • Specialist repair and maintenance of vacuum pumps and pump stands of all types and manufacturers - also contaminated pumps and devices
