The TriVac T series of pumps are suited for pumping water vapor within the specified water vapor tolerance limits. Condensable vapors that can liquify when being compressed inside the pump and exceed the vapor tolerance of the pump should be avoided. In the case of wet processes we recommend the installation of liquid separators upstream and downstream of the pump as well as the use of the gas ballast. Trivac T pumps are not designed for pumping dusty, aggressive, corrosive, flammable or explosive gases or gas mixtures, or for pumping oxygen or other highly reactive gases in concentrations greater than in normal ambient atmosphere (>21%).

Applications Include:
• Backing high-vacuum pumps (turbo, diffusion, cryo...)
• Backing roots pumps
• Backing mass spectrometers
• Refrigeration system evacuation
• Epoxy degassing
• Vacuum sterilization
• Freeze drying
• Vacuum centrifugal applications
• Vacuum distillation
• Space research
• Other vacuum processes

We carry repair kits for most of the pumps we sell, have welded and modular chambers of all sizes, and have all the fittings, hoses, valves, gauges, and other accessories needed to build your custom vacuum solution.
