Oil-sealed vacuum pumps are used in various fields of vacuum technology and are suitable for both industrial productions and research applications.
These pumps are preferred due to their reliability, low cost, and proven technology. The use of oil enables higher compression ratios and improves internal cooling behavior. Oil-sealed vacuum pumps have demonstrated their performance in demanding applications such as the food industry, heat treatment, coating, as well as in reliable long-term applications such as mass spectrometry.
Among the various vacuum pump technologies, rotary vane pumps are referred to as displacement pumps. These pumps mechanically capture a volume of gas and move it through the pump, creating a vacuum on the inlet side.
Since the gas to be pumped comes into contact with oil, they are often referred to as "wet" pumps. The oil is used as a lubricant. To achieve a lower ultimate pressure, the oil is carefully selected and specially developed for the application.
Rotary vane vacuum pumps are manufactured in single-stage and two-stage versions. Two-stage pumps achieve lower ultimate pressures than single-stage pumps.
Oil-sealed pumps are tolerant to water vapor by opening the gas ballast. To extend the lifespan of your vacuum pumps, regular oil changes are recommended as part of routine maintenance.
