Distilled vacuum pump oil is mixed with specific solvents, which aid in lubrication, oxidation resistance, and foaming resistance. These characteristics are important for vacuum pump oil, as they increase the life and performance of the pump and the oil itself. Hydrotreated pump oil, however, does not share the same solubility as distilled pump oil. This means hydrotreated oils do not mix with the necessary additives our trade-specific vacuum pumps require. This can damage a vacuum pump and decrease vacuum efficiency if not used in the appropriate application. A seal in a vacuum pump between its high pressure and low pressure, or induction and exhaust sections of the pumping process, specifically for rotary vane pump application, allows for separation of gas and oil within the pump, reducing unwanted contamination. If you look at the video above, the seal needs to be created at the top of the rotor and in between the vanes and the chamber. The primary role of most oils is mechanical lubrication, and the vacuum pump is no different. Additionally, the vacuum pump oil seals the vanes in rotary vane pumps, cooling the pump through heat transfer between the inner and outer parts of the pump. Provides a seal across the vanes and duo seal between the high pressure and low-pressure side of the pump in two-stage pumps

Change whenever you observe discoloration of the oil, whether it is a change to creamy from moisture or if it's darkening from other contaminants or heat.

They are designed for most laboratory applications, both routine and research. When choosing a vacuum pump, consider your application type, sample composition and operating parameters.Change pump oil based on the manufacturer-approved method but generally when the oil is warm. Make sure to dispose of the oil in a legal and approved location. Mobil Vacuum Pump Oil 100 has a high degree of chemical stability enabling it to resist oxidation and the subsequent formation of sludge and deposits, an essential characteristic in all cases where continuous service in involved. This enables the oil to retain its original properties such as viscosity and demulsibility and so prolong oil service life.

Our vacuum pump oil is designed to have a low vapor pressure, much lower than the moisture in the HVAC/R system, ideally discharging it to the atmosphere. Low vapor pressure means having lower evaporative properties, where high vapor pressure has high evaporative properties. Because the vapor pressure of the pump oil is very low, it can operate at extremely low pressures without evaporating. The deeper the vacuum, the lower the pump oil vapor pressure must be, which can become a factor in ultra-deep vacuums used in some industries and scientific experimentation. It transfers contaminants from the pump to the atmosphere through pressure difference and evaporation As soon as there is a notable difference from its original clear state is a good time to change your oil. The signs above of contaminated vacuum pump oil help you determine whether your vacuum pump oil has altered its ability to keep its designed viscosity or its vapor pressure for maximum efficiency. A gas ballast provides a way to allow air to enter into the pump during the initial stage of vacuum to help prevent moisture contamination and fouling of the oil on wet systems. The podcast concludes with a reminder that extensive training content on HVAC topics like this is available through HVAC School and other industry experts. Continuing education and an open, collaborative mindset are important for professional growth.When the vacuum pump is not reaching the desired vacuum level. This is best tested with a vacuum gauge placed directly on the pump. Vacuum pump oil recycling is typically done by specialised oil recycling companies, who use equipment and processes to separate the oil from contaminants and restore its properties. This process can help extend the life of the oil and reduce waste and environmental impact by reducing the need for disposal of used oil. Because vacuum pumps don’t have filters, the oil inside will eventually become saturated with contaminants, which reduces the pump’s efficiency.
