What is a Vacuum Pump Impeller?  

A vacuum pump impeller is a rotating component within a vacuum pump that accelerates fluid (typically gas or air) to create suction and maintain vacuum pressure. It consists of curved blades or vanes that spin at high speeds, drawing in air or gas and expelling it to generate a vacuum.  

How Does a Vacuum Pump Impeller Work?  
1. Intake Phase: The impeller rotates, creating a low-pressure zone that draws gas or air into the pump.  
2. Compression Phase: The trapped gas is compressed as it moves along the impeller blades.  
3. Discharge Phase: The compressed gas is expelled, maintaining the desired vacuum level.  

This continuous cycle ensures efficient vacuum generation, making impellers essential in applications requiring precise pressure control.
