Description
The Welch 1402 DuoSeal Belt Drive Rotary Vane Mechanical Vacuum Pump is a high-performance, dual-stage vacuum pump designed to deliver superior vapor handling capabilities. Known for its legendary longevity and exceptional durability, the pump is ideal for applications including vacuum furnace evacuation, rotary evaporation, refrigeration system evacuation, vacuum sterilization, freeze drying, and other vacuum processes. Despite its current condition requiring repair, it is being offered AS-IS due to its ability to power on with weak vacuum pressure, making it an excellent choice for those seeking valuable spare parts or a project to restore its function. Operating at 115VAC with a free air displacement of 5.6 CFM and an ultimate pressure of 1x10-4 Torr, this unit displays a cool running design with a large oil reservoir and high oil feed port to dilute contaminants and draw clean oil. Perfect for scientific and industrial use, the Welch 1402 provides a reliable vacuum solution for challenging applications.
