Vacuum Pump Oil Contamination

Vacuum Pump Oil Contamination

Oil sealed pumps require oil to create a vacuum. Oil that is contaminated or which has thermally started breaking down needs to be replaced in order to maintain vacuum and keep the pump running properly. Proper maintenance can prevent the need to replace the pump altogether.


Vacuum pump maintenance is a requirement for long-lasting equipment. If the vacuum pump is installed and used correctly, and there is no contaminated oil, it is likely to work for a long time. Always fill your pump with the correct amount, and be sure to use clean oil to help maintain function over a long period of time. Below are some tips for maintaining your oil.


Drain & Fill


In order to change the oil, the pump must first be drained. It is important to run the pump for a few minutes before draining. This warms it up, preventing the oil from separating from its contaminates. If the oil does not separate, the pump will still have contaminates, and putting new oil in a contaminated pump will only cause more problems. Running the pump first will also help with draining the entirety of the oil from the tank.




Now it is time to refill the tank with clean oil. The oil you choose will certainly make a difference. Low-quality oil can mean a less effective pump and a shorter lifespan. Keep your pump running efficiently by using high-quality oil.


Maintenance is Key


To keep your pump functioning at a reasonable degree, you have to do the maintenance required. If you are uncertain about how to change contaminated oil, don’t be afraid to call a technician to assist.


Is it Worth it?


Replacing a vacuum pump is much more costly than changing the oil, even when using high-quality oil. After a while, when many oil changes have been done, you may find that your pump still isn’t performing as expected. The wear parts inside the vacuum pump may need replacement.
