Oil-Sealed Rotary Piston Pumps Maintenance Tips

Oil-Sealed Rotary Piston Pumps Usage


Oil-sealed rotary piston pumps are widely used in the chemical, pharmaceutical, and other industries as they are ideal for generating vacuum at low and medium pressures. However, like all other machines, these pumps require regular maintenance to function at their best capacity. In this article, we will discuss some maintenance tips for oil-sealed rotary piston pumps to ensure optimal performance and longevity of the equipment.

Common Issues

Oil Contamination

One common problem faced by users is oil contamination, which can affect the performance of the pump. Contaminants such as water, dust, and other particulate matter can mix with the oil and lead to poor performance or even damage to the pump.

Wear and Tear

Another issue that can arise is wear and tear of the pump due to regular usage. This can cause a decrease in performance and efficiency, and can even lead to pump failure if not addressed in time.


Regular Oil Changes

To prevent oil contamination, it is essential to perform regular oil changes on the pump. This will remove any contaminants and ensure that the pump is running on clean oil, thus improving performance and increasing the longevity of the equipment.

Maintenance Checks

To prevent wear and tear, it is recommended to perform regular maintenance checks on the pump. This includes checking the oil level, cleaning the pump, and replacing any worn or damaged parts as needed.

Steps to Take

  1. Perform regular oil changes to prevent oil contamination.
  2. Perform regular maintenance checks on the pump to prevent wear and tear.
  3. Replace any damaged or worn parts as needed.
  4. Clean the pump regularly to prevent dust and other particulate matter from accumulating.
  5. Ensure that the pump is stored in a dry and cool place.

Points to Note

  • Always use the recommended oil for the pump.
  • Ensure that the pump is turned off before performing any maintenance checks.
  • Always wear protective gear when working with the pump.
  • Do not overfill the oil in the pump.
  • Ensure that the pump is properly grounded.
