Operators using the ProBoost Diffusion Pump often face downtime or contamination risks during maintenance or system transitions. The roughing isolation valve solves this by cleanly separating the diffusion pump from the roughing line, preserving vacuum integrity and reducing pump wear.

This video demonstrates how the valve functions within the ProBoost system, what to check during installation, and how to troubleshoot common issues. It’s designed for field engineers, maintenance leads, and system integrators working with high-vacuum setups.

Key takeaways from the video

  • Purpose of the valve: Prevents backstreaming and isolates the diffusion pump during roughing cycles.
  • Installation tips: Align valve orientation with flow direction; confirm seal integrity before activation.
  • Operation sequence: Valve opens only after roughing pressure stabilizes; closes automatically during pump shutdown.
  • Maintenance cues: Watch for delayed actuation or seal degradation—both signal replacement needs.
  • System compatibility: Designed specifically for ProBoost models; retrofitting to other pumps requires adapter kits.

FAQs

It prevents oil vapor backstreaming into the vacuum chamber and shields the diffusion pump from pressure surges during roughing.
