Advanced lubrication solutions for vacuum pumps: superior efficiency, durability and performance. 

Vacuum and ultra-vacuum pumps are crucial components in a variety of industrial and scientific sectors. Their efficiency and reliability largely depend on correct lubrication. Lubrication plays a fundamental role by fulfilling several key functions:

• Friction reduction > Lubricating oil creates a protective film between the pump's moving parts, minimizing friction and wear. This translates into longer pump life and lower energy consumption.
• Better sealing > Helps seal micro-leaks between moving parts, ensuring higher vacuum and greater pumping efficiency.
• Corrosion Protection > Lubricating oil protects metal surfaces from corrosion, extending the life of the pump.
• Heat dissipation > Helps dissipate heat generated by the pump, preventing overheating and component damage.

Key points of a lubricating oil for vacuum and ultra-vacuum pumps:

A vacuum pump lubricating oil requires a targeted formulation to meet a range of essential criteria; no detail in its composition must be overlooked:

• High thermal stability > To resist the high temperatures generated during operation.
• Low vapor pressure > To minimize vacuum contamination and ensure an adequate working environment.
• High viscosity index > To ensure effective lubrication over a wide range of operating temperatures.
• Compatibility with materials> To avoid unwanted reactions with the pump components and with the gases intercepted and extracted from the chamber.
• High efficiency in de-emulsification > Guarantees rapid separation from water and other pollutants. This is essential because water can form emulsions with oil, creating a compound that risks negatively affecting the operation of the pump.

• thermal stability: resistance to temperature changes without degradation.
• low volatility: minimizes oil loss through evaporation.
• good sealing ability: maintains the desired vacuum while preventing air from entering.

High vacuum: from 10-3 mbar to 10-7 mbar

• chemical compatibility: chemical inertia with respect to materials and gases.
• minimal back diffusion: limits the diffusion of the oil towards the vacuum chamber.
• low vapor pressure: reduces oil vapor emissions.
  
  

Ultra vacuum from: less than 10-7 mbar

• ultra low vapor pressure: prevents the emission of vapors that could affect the vacuum.
• high purity and chemical stability: absence of impurities and resistance to decomposition.
• compatibility with purification systems: suitable for purification processes to maintain vacuum levels adequate for the application context.

Why use  a custom lubricating oil based on your design?

In the ultravacuum sector, there are particularly critical application contexts that require optimal and specific performance from pumping technology, where customized lubrication plays a fundamental role. Here are some examples:

• Scientific Research and Laboratories: Ultravacuum is crucial for reducing interference from gas molecules in studies such as particle physics and mass spectrometry.
• Semiconductor Manufacturing: Extremely low vacuum levels are critical to avoiding contamination and ensuring high quality in the manufacturing of chips and semiconductors.
• Space Technology: To test satellites and components, vacuum chambers that simulate space are used, requiring ultravacuum
• Nanotechnology and Nanomaterial Manufacturing: Ultravacuum environments are necessary to prevent contamination and enable precise deposition processes in the production of nanomaterials.

In all these contexts, adequate and customized lubrication of vacuum pump oil is crucial. Choosing an oil specific to your unique operating conditions and application requirements not only ensures optimal performance is maintained but also results in significant benefits in terms of equipment life and reliability.
