Precautions for the use of vacuum pump oil

1. In order to ensure the normal operation of the vacuum system, it is necessary to prevent the entry of pollutants such as mechanical impurities and water during use, storage and transportation, so as not to affect the service life of the vacuum oil and the normal operation of the system.

2. Residual oil often contains a large amount of pollutants and aging products, which will seriously affect the quality and life of new oil. Therefore, when changing oil, the oil tank and oil circuit should be cleaned. Pour new oil from the suction port of the pump, and slowly turn the pump shaft by hand to clean the pump cavity and drain the residual oil. Repeat the cleaning agent several times.

3. The quality of vacuum pump oils of different brands and varieties is different. If they are mixed, it may cause changes in oil quality. Therefore, different types of vacuum pump oils cannot be mixed.

4. When used for solvent, water vapor and corrosive gas, it should be checked frequently after use. When the oil is emulsified or diluted to affect the sealing performance of the vacuum pump, the oil should be changed.

Precautions for the use of vacuum pump oil

What are the performance characteristics of vacuum pump oil?

The vacuum pump oil has anti-rust, anti-corrosion and oxidation stability; it can quickly separate the water entrained in the oil, so that the vacuum pump can reach the required vacuum degree; the low vapor pressure prevents the oil from flowing out of the inner cavity of the pump The backflow to the vacuum system diffuses into return oil to ensure sufficient ultimate vacuum pump. The vacuum pump oil can protect the vacuum pump, so that the vacuum pump can perform better and prolong the service life.

What are the performance characteristics of vacuum pump oil?

Vacuum pump oil performance characteristics

The main performance requirements of vacuum pump oil include the following:

1. Very low vapor pressure

2. Appropriate viscosity and good viscosity-temperature characteristics

3. Good thermal oxidation stability

4. Good corrosion resistance and demulsibility

5. Higher flash point

6. Lower ultimate pressure

Frequently Asked Question

Do you have any question?

Liquid ring vacuum pumps generally require an ISO 22 or ISO 32 viscosity. Rotary vane vacuum pumps normally utilize an ISO 68 (SAE 20) or ISO 100 (SAE 30) oil. Process pumps and other vacuum pumps driven by a gearbox will require a much more viscous oil, such as an ISO 220 (SAE 50).

Unlike motor oil that contains many additives, vacuum pump oil additives are limited to corrosion resistance, anti-oxidation and perhaps foaming. For applications that may contain high percentages of oxygen, acids and hazardous gases there are alternative synthetic fluids available.

SPX OTC Premium High Vacuum Pump Oil is designed to maintain maximum viscosity at high running temperatures. It has lower moisture content than other oils and improves cold weather starts.
