What is Vacuum Pump Oil?

Vacuum pump oil is a special type of oil that plays an important role in the vacuum pump process. The applications of vacuum pump oil include lubricating components, cooling, reducing noise, preventing wear on other pump parts, and reducing friction by up to 20%. It should be noted that there are different types of vacuum pumps, each requiring its specific oil. Using the appropriate oil ensures better pump performance and longer lifespan.

Choosing Vacuum Pump Oil

Selecting the right vacuum pump oil is as important as the pump itself, since the proper functioning of the vacuum process and creating the desired vacuum space depend on the oil quality. Suitable oil not only provides effective lubrication and cooling but also prevents evaporation and contamination, extending the pump’s lifespan. When choosing oil, consider the following factors:

Parameters for Choosing Vacuum Oil

Maximum achievable vacuum pressure: The oil must perform under low pressures and maintain the vacuum.

Operating environment: The oil should function properly under specific temperatures, humidity, and environmental conditions.

Oil lifespan and operating hours: The oil’s life should align with the pump’s maintenance schedule.

Heat resistance: The oil must withstand high temperatures and operational pressures to prevent decomposition and oxidation.

Cost of vacuum oil: The oil price should fit within the budget and the pump’s operational efficiency.

Viscosity: The oil’s thickness must match the pump type and capacity for effective lubrication.

Non-reactivity with contaminants: The oil should not react with particles or gases in the environment, maintaining its properties.

By considering these factors, you can select oil that optimizes pump performance and extends equipment life.

Models and Brands of Vacuum Pump Oil

As mentioned earlier, to ensure proper pump operation, the correct oil should be used according to the pump type. Using inappropriate oil may result in repairs or even replacement of the pump. Common types of vacuum pump oils include:

Properties and Features of Vacuum Oil

One of the most important characteristics of vacuum pump oil is very low vapor pressure. Since vacuum pumps operate under high vacuum conditions, the oil must not evaporate under low pressures and should provide both effective lubrication and cooling simultaneously.

Very low vapor pressure

Stability in nature and form

Non-corrosive and non-abrasive

High viscosity

High heat tolerance

Oil Replacement Time for Vacuum Pumps

The operating hours of oil vary among different models of oil-based vacuum pumps. Considering environmental dust and operating conditions, the oil lifespan and replacement intervals differ. Replacement time can range from 200 hours to several thousand hours. For precise information, refer to the pump’s user manual.

Conclusion

In general, oil is widely used in equipment for lubricating parts. In vacuum pumps, oil is used for cooling the pump and lubricating its components. Oil is a very important accessory for vacuum pumps. Vacuum oil must have specific characteristics, the most important being very low vapor pressure. If the vapor pressure is high, part of the oil will evaporate during vacuum creation, reducing its ability to lubricate and cool the pump, which significantly decreases the pump’s efficiency.
