Top 10 Oil Sealed Vacuum Pump Factory in China 2026

Introduction to Oil Sealed Vacuum Pump

An oil - sealed vacuum pump is a type of positive - displacement pump that uses oil as a sealing and lubricating medium. It operates by creating a vacuum through the movement of mechanical components within a chamber filled with oil. The oil serves multiple crucial functions. Firstly, it seals the clearances between the moving parts, preventing gas from leaking back into the evacuated space. Secondly, it lubricates the components, reducing friction and wear, which in turn extends the pump's service life. Thirdly, it helps to cool the pump by absorbing the heat generated during the compression process.

Oil - sealed vacuum pumps are widely used in various industries such as semiconductor manufacturing, food packaging, pharmaceutical production, and scientific research. In semiconductor manufacturing, they are used to create a clean and controlled vacuum environment for processes like thin - film deposition and etching. In the food packaging industry, they are employed to remove air from packages to extend the shelf - life of products.

Now, let's take a look at the top 10 oil - sealed vacuum pump factories in China in 2026.
