Since there are many brands of vacuum pumps and various models adapted for different applications, always consult the instructions or an equipment technician or engineer to understand the correct frequency and manner of performing maintenance. Some vacuum pumps require less maintenance than others, while some require different tools and techniques. Most vacuum pumps require regular oil changes. This is a simple task that can increase the lifespan of your equipment if performed routinely. Firstly, remove any dirt, oil, and debris that may be left behind on the vacuum pump with a soft cloth. Large accumulations of dirt and debris may require the use of an industrial degreaser around the exterior before continuing. Oil acts as a coolant, sealant, and lubricant for your vacuum pump. As such, it’s important that you regularly perform oil changes to encourage safe and efficient operation of the vacuum pump for years to come. There are a few ways to tell when your oil needs to be changed. The easiest is often with a visual inspection. Compare clean, unused oil to a sample taken from the vacuum pump. If you’re noticing a significant difference between the two, such as cloudy or dark spots in the machine’s oil, it should be changed. The second method may be more efficient if you own many vacuum pumps and need to perform routine maintenance on all of them. Purchase a micron gauge to quickly and efficiently inspect whether or not the oil needs to be changed in your vacuum pumps. Don’t forget to wear personal protective equipment such as gloves whilst changing the pump’s oil.
