We serve industries such as manufacturing, pharmaceuticals, chemical, Edible Oil, Food and dairy. Oil-sealed rotary vacuum pumps, also known as oil-lubricated vacuum pumps and rotary vane pumps are a type of positive displacement pump commonly used to create vacuum in various industrial and scientific applications.

Here's how they function:

1. Rotary Mechanism: The pump comprises a rotor with several vanes that slide in and out of slots within the rotor. This rotor is eccentrically mounted inside a cylindrical casing. As the rotor turns, the vanes sweep across the inner surface of the casing.
2. Oil Sealing and Lubrication: These pumps utilize a small amount of oil, typically mineral oil, to seal the gaps between the vanes and the casing, creating an effective seal. Additionally, the oil lubricates the moving parts of the pump, reducing friction and wear.
3. Compression: Gas or vapor is drawn into the pump through the inlet port. As the rotor continues to rotate, the vanes trap the gas pockets between them and the casing, compressing the gas. The compression process continues as the gas moves towards the outlet port.
4. Discharge: The compressed gas exits the pump through the outlet port, typically into a receiving vessel or vacuum system.
5. Oil Management: To maintain proper sealing and lubrication, these pumps require a continuous supply of fresh oil. Some pumps are equipped with oil reservoirs, and mechanisms for oil recirculation and filtration ensure the oil remains clean and effective. Regular monitoring of oil levels and occasional oil changes are necessary maintenance tasks.

Oil-sealed rotary vacuum pumps are valued for their relatively high vacuum levels, quiet operation, and ability to handle a wide range of gases. They find applications in industries such as chemical processing, pharmaceuticals, food and beverage, semiconductor manufacturing, and research laboratories. However, they may not be suitable for applications involving reactive gases or where oil contamination is a concern. Proper maintenance, including oil changes and occasional replacement of vanes, is crucial to ensure the pump's optimal performance and longevity.
