Comprehensive Guide to Screw Vacuum Pumps

Screw vacuum pumps are advanced devices that utilize dual intermeshing screws rotating in opposite directions to create vacuum conditions. Known for their oil-free operation and high efficiency, these pumps are integral in industries requiring clean and reliable vacuum solutions.

Working Principle

Interactive diagram illustrating the screw vacuum pump’s internal mechanism.
  • Air Intake: Gas is drawn into the pump through the inlet.
  • Compression: The gas is trapped between the screw threads and compressed as it moves towards the exhaust.
  • Exhaust: The compressed gas is expelled through the outlet, creating a vacuum at the inlet.
