Introduction to Oil Ring Vacuum Pump
An oil ring vacuum pump is a type of positive - displacement vacuum pump. It operates based on the principle that a rotating impeller inside the pump creates an eccentric motion. The oil in the pump forms a ring due to centrifugal force, which acts as a sealing and working medium. This pump is widely used in various industries such as chemical, pharmaceutical, food processing, and electronics. It can provide a relatively stable vacuum environment, is suitable for continuous operation, and has good corrosion - resistance and reliability in many cases.
Now, let's take a look at the top 10 oil ring vacuum pump manufacturers in China in 2025.
