Synthetic Oil for Vacuum Pumps Synthetic vacuum pump oil offers several benefits over other types of lubricants. It has a lower vapor pressure, which means it evaporates less readily and produces fewer deposits in the vacuum system. This helps to improve the overall efficiency and performance of the pump. Synthetic oils also have better oxidation and thermal stability than mineral-based oils, which means they can withstand higher temperatures without breaking down or losing their lubricating properties. This makes them an ideal choice for use in high-temperature vacuum applications. In addition, synthetic oils have better chemical stability than mineral oils, which means they are less likely to degrade in the presence of chemicals or gases. This makes them an ideal choice for vacuum pumps that are used in applications where exposure to chemicals or gases is common. By using the right synthetic oil and following proper maintenance procedures, you can help extend the life of your vacuum pump and ensure optimal performance.
