Dry Vacuum Pumps

A Dry Vacuum Pump Has the Following Important Process Related Characteristics:

Advantages:

• Dry - no added fluids to be discharged. Absolutely no chance for back migration in the suction line
• Handles Dry gases (and vapors that don't condense) well

Disadvantages:

• Risk of damage from liquids, solids, or corrosive condensed vapors
• Runs hot
  - Potential polymerization and build-up of product
  - Potential auto-ignition of product
• Moving parts with tight clearances
  - Run time wear (heavily dependent on application)
  - Damaged if overheated
• Complex
  - Requires controlled cooling and nitrogen purge sub systems
  - Requires careful start up and shut down procedures
• Size (capacity) limitations (ex. 15 lb/hr at 2 mm HgA is 1240 ACFM)
• More expensive to buy and maintain
