Sogevac SV220B Single Stage Rotary Vane Pump SV220 SV300B SV320B SV470B Oil Sealed Pump

Product Description

The SV22B Rotary vane pump is a high-performance vacuum pump, a world famous brand in the vacuum technology sector. The following is an introduction to it:

Structure
- Cylindrical housing: The pump has a cylindrical housing which serves as the basic framework to contain internal components such as the rotor and vanes.
- Eccentric rotor and vanes: Inside the housing, there is an eccentrically placed slotted rotor. The rotor is equipped with vanes that are usually forced outwards by centrifugal force or springs, enabling them to slide along the inner wall of the housing.

Working Principle
Gas enters the pump through the intake port. As the rotor rotates, the vanes divide the pump chamber into different spaces. The volume of the space where the gas is located gradually expands during the rotation, causing the gas to be sucked in. Then, as the rotation continues, the volume of the space decreases, and the gas is compressed and finally ejected from the pump through the exhaust port.

Features and Advantages
- High pumping speed: It can quickly pump out the gas in the vacuum system to achieve the required vacuum degree.
- Low noise and vibration: Advanced design and manufacturing technology ensure that the pump operates with low noise and vibration, which helps to create a relatively quiet working environment and reduces wear and tear on equipment and components.
- Good sealing performance: With reliable sealing technology and structure, it can effectively prevent gas leakage and ensure the stability and reliability of the vacuum pumping process.
- Wide working pressure range: It can work stably in a wide pressure range from atmospheric pressure to a relatively low vacuum pressure.

Applications
- Semiconductor industry: It is used in processes such as semiconductor manufacturing, thin film deposition, and etching to provide a high-quality vacuum environment.
- Vacuum coating: In the vacuum coating process, it helps to create a vacuum environment to ensure the quality and adhesion of the coating.
- Laboratory research: It is widely used in various laboratory experiments that require a vacuum environment, such as vacuum drying, vacuum distillation, and material degassing.
- Food packaging: It is used for vacuum packaging of food to extend the shelf life of food by removing air in the packaging.
