Vacuum pump oil

Industrial high vacuum pump oil

Vacuum pump lubrication requires specialized low-vapor-pressure oil to lubricate, seal, and cool the pump components. Key maintenance includes choosing the right lubricant—usually mineral Molylub VacTec M series oil for general use or synthetic Molylub VacTec A series for high-temperature/demanding tasks (often ISO 68 or 100)—and changing it regularly to prevent sludge and moisture contamination.

Ester oil is known for its excellent lubrication properties, and it is commonly used as a lubricant for vacuum pumps. One of the primary benefits of using ester oil in vacuum pumps is its ability to maintain consistent lubrication properties over a wide range of temperatures. This means that it can provide effective lubrication even in high-temperature vacuum applications where other types of lubricants might break down or lose their lubrication properties

Synthetic ester vacuum pump fluid

Molylub VacTec E is a combination of high-grade synthetic ester base fluids and specially engineered additive systems. It offers high performance protection of vacuum pumps operating under extreme conditions: high load and temperatures, compressing reactive and dirty gases, intermittent operation, in warm or cold climates and in mobile applications.

Molylub VacTec PF – Perfluoropolyether (PFPE) oil is a type of synthetic lubricant that is commonly used in vacuum pumps. It is a high-performance oil that offers a range of benefits over other types of lubricants. Exceptional chemical resistance – unique molecular structure that provides excellent chemical stability, making it highly resistant to degradation from acids, bases, and solvents.

PFPE Oil for Vacuum Pumps

Molylub VacTec PF – PFPE oil is a special lubricant that is non-reactive to oxygen and 100% non-flammable, ensuring total safety for the pump and machinery. It is also optimal for use in the food industry because it is completely odorless and colourless.

Special vacuum pump applications involve creating specific, controlled environments for industrial processes, including semiconductor manufacturing, pharmaceutical freeze-drying, vacuum coating, degassing, and sterile medical suction. These pumps, such as dry screw or rotary vane types, are critical for removing moisture, oxygen, gases, or contaminants in high-precision, clean, or harsh environments.

Silicon diffusion pump oil

Molylub VacTec Silo vacuum pump silicone oil is a high-performance synthetic fluid designed for high-vacuum, high-temperature, and corrosive applications, notably in diffusion pumps. It offers excellent thermal stability, low vapor pressure, and resistance to oxidation, making it ideal for semiconductor manufacturing, thin-film coating, and research labs.
