Lubricants and oils for vacuum pumps

Vacuum pumps are similar to compressors in that they are a mechanical device used to move a stream of gas, however, in the case of vacuum pumps, they are designed to create a negative pressure.

Vacuum systems can be adversely affected by leaks and materials that have high levels of outgassing. Lubricants and other materials should be selected with these aspects in mind to ensure good vacuum system performance.

An additional challenge is that contamination from the process stream can adversely affect the quality of the lubricant and degrade it rapidly. Contamination can also damage internal vacuum pump components exposed to the gas stream.

The purpose of a high-quality lubricant with the correct viscosity is to withstand the gas stream while also protecting the internal components to maximize the long-term reliability of the vacuum pump.
