Diffusion Vacuum Pump

Diffusion vacuum pumps are a type of vacuum pump that operates based on the principle of molecular diffusion. They are commonly used in various industrial applications where high vacuum levels are required.

Diffusion vacuum pumps consist of a heated oil or mercury vapor source, which releases vapor molecules into the pump chamber. These vapor molecules then collide with gas molecules present in the chamber, causing them to move towards the pump outlet. As a result, the gas molecules are gradually removed from the chamber, creating a vacuum.

These pumps are known for their ability to achieve high vacuum levels and are often used in applications such as semiconductor manufacturing, vacuum coating, and research laboratories. They are particularly effective in pumping out gases with low molecular weights, such as hydrogen and helium.

In the supply class "Compressors And Vacuum Pumps" and the supply group "Pumps And Compressors," diffusion vacuum pumps are categorized as a specific type of vacuum pump that falls under the broader category of compressors and vacuum pumps.
