Vacuum Pump Oil

Why Does Your Vacuum Pump Need Oil?

Vacuum pump oils and lubricants play an important role in a range of different micro-processes within the inner workings of your vacuum pump. Probably the most obvious use of vacuum pump oil is to lubricate your system, enabling all the moving parts to operate seamlessly to prevent the high temperatures and wear caused by friction. Another example is to clean your vacuum pump, as the oil helps to move impurities from the pump into the filter for removal. Vacuum pump oil also helps to seal and protect your system by creating a barrier between any open gaps. This helps to maintain compression. Finally, vacuum pump oils and lubricants help to cool your system, as they enable your pump to maintain optimum operating temperatures.

What to Consider When Choosing a Vacuum Pump Oil? 

When considering which vacuum pump oil is right for your systems and operations, there are a few factors that are important to consider. One of these is the suggested or predicted change interval, which dictates the lifetime of the oil or lubricant. Oils that require more frequent change may add on costs, but by ensuring the lubricant is refreshed more often, you can better rely on the quality of the oil. You also need to consider whether the lubricant you want to go for is thermally stable, meaning it can cope with high temperatures without breaking down. Vacuum pumps can generate a lot of heat, so this is a vital consideration as if oil isn’t thermally stable, it won’t work efficiently and will need to be replaced often. An effective vacuum pump oil should also have a lubricity resistance to oxidation, meaning that it is comprised of a robust molecular structure that is resistant against oxidisers. The solvency of a vacuum pump oil is also important, as well as whether or not it competes with additives. All of these points are important to take into consideration when picking the optimum oil or lubricant for your vacuum pump system.

The Importance of Using Genuine OEM Vacuum Pump Oil:

As with all parts and accessories, using products that are 100% tried and tested to comply with your system is essential. This is because choosing third-party alternatives can put your investment at risk, as they may not be compatible, causing costly damage and wear. This same concept applies to vacuum pump oil.
