This Welch Duo-Seal 1400 Belt Drive Rotary Vane Vacuum Pump is in used condition, has been tested and is guaranteed to be fully functional. This pump came from a local lab that had surplus equipment. We urge customers to view all photos as they show overall condition, included accessories and useful information. Please feel free to contact us with any questions. Please Note: Oil will be drained prior to shipping and will not be included. Oil must be obtained and filled by buyer prior to running pump. Belt-drive operation reduces wear and RPM for a very quiet and durable pump with a very low ultimate vacuum of less than 0.001 Torr [0.1 micron] Time tested design is well known and easy to find repair kits, replacement parts, and service technicians certified to make repairs These pumps have large oil reservoirs to dilute contaminants which allows for a high contamination tolerance Laboratory applications include: vacuum manifolds, (Schlenk Lines), high boiling point evaporations (to 195 deg. C), glove boxes, vacuum distillation, vacuum furnace evacuation, backing turbomolecular pumps, backing diffusion pumps, refrigeration system evacuation, epoxy degassing, vacuum sterilization, backing mass spectrometers, freeze drying, vacuum centrifugal applications, space research, general laboratory and other vacuum processes. Industrial applications include: neon sign repair, HVAC, thin film deposition, vacuum tube cathode ray and lamp/lightbulb manufacturing, semiconductor manufacturing etc.
