Screw Vacuum Pumps

Our dry-running screw technology delivers contact-free vacuum generation with zero lubrication required in the pumping chamber. This ensures no process contamination and clean operation. Designed for high vapor and liquid tolerance, screw vacuum pumps are easy to service, durable, and offer remarkably low life cycle costs.
The pump housing features synchronized screw rotors that compress gas efficiently while reducing noise and vibration. Variable pitch models enhance efficiency by cooling gas during each pitch change. Cooling is achieved through a water-cooled outer chamber, ensuring consistent performance in demanding environments.

How it Works: Dry Screw Vacuum Pumps

The S-Series screw vacuum pumps operate on the principle of internal compression, using synchronized screw rotors for efficient, contact-free operation.
Two parallel screw-shaped rotors—one with a right-hand thread and the other with a left-hand thread—turn in opposite directions inside the compressor housing without friction. Gas is transported into the compression chamber, where it is compressed axially from the suction side to the discharge side.
In variable pitch models, the gas is cooled at each pitch change, optimizing efficiency and reducing heat buildup. Cooling is achieved through a water-cooled outer chamber, with optional cooling gas for specific pump sizes. This design ensures durability, low noise levels, and minimal vibration, making the S-Series pumps ideal for demanding industrial applications.
