Working Principle

The screw vacuum pump utilizes a pair of screws that rotate synchronously at high speed in opposite directions within the pump casing to perform suction and exhaust operations. The two screws are finely balanced for dynamic correction, and there is a certain gap between them. As a result, during operation, there is no friction between the screws, ensuring smooth operation, low noise, and no need for lubricating oil in the working chamber.
