Vacuum pump oil isn't just oil

Running and maintaining your high-performance vacuum pump and applications means constantly staying on top of performance and degradation. We'll briefly explore the process which relies on 3 critical components:

  • Applications types - industrial processes, coating technology, research & development . . .

  • Vacuum pump types - oil-sealed, semi-conductor, diffusion . . .

  • Selected grease, oil or lubricant - chemical composition, frequency, and ease of maintenance . . .

Which oil is compatible with my vacuum pump?


Mineral oils offer a high degree of compatibility with elastomers and resistance to hydrolysis.

Frequently also termed semi-synthetic oils, hydrocracked oils are produced under a very high hydrogen pressure at high temperatures and are substantially free of aromatic compounds and olefins.

These oils exhibit:

  • Higher thermal stability compared to conventional mineral oils

  • In most cases, the intervals between the oil changes can be extended

Compounding vacuum pump performance

Ester oils are ideally used for vacuum pump applications involving high thermal dynamics.

Some of their primary properties include:

  • High temperatures

  • Average elastomer compatibility

  • Average hydrolysis resistance


Cool temperatures, hot results

Polyalphaolefin oils are synthetic hydrocarbons which are paraffin-like, yet contain a uniform structure. Thermal and chemical resistance is better compared to mineral oils.

They have great flowing properties when cold, meaning they are especially effective at:

  • Low temperatures

  • Elastomer compatibility

  • Resistance against hydrolysis


Hassle-free at high temperatures

PFPE oils are practically inert against all chemical and oxidizing influences, and will not polymerize under the influence of high energy radiation. A few points to bear in mind:

  • Reactions may take place at temperatures over approximately 150 °C (302 °F)

  • Perfluoropolyether is highly stable thermally and isn't flammable

  • Thermal decomposition may only take place at temperatures of over 290 °C (554 °F).

Diffuse your results

Vacuum pump fluids for oil diffusion pumps must exhibit a low vapor pressure at room temperature and must be able to resist thermal decomposition and oxidization to a large extent. This means:

  • The surface tension of the pump fluids must be high to reduce the creep of oil films
  • They must be chemically inert, exhibit a high flash point and evaporation heat must be low
  • The pump fluids should permit high pumping speeds over a wide range of pressures and be cost-effective
