Welch 1405B-80 DUOSEAL MOUNTED PUMP 115V, 60Hz 1Ph, CSA
Welch 1405B-80 DuoSeal Vacuum Pump 115V 60Hz CSA – Complete Mounted Unit
The Welch 1405B-80 is a fully mounted, ready-to-run DuoSeal belt drive vacuum pump. This complete 115V 60Hz 1Ph unit delivers 3.2 CFM (90 L/min) free air displacement and reaches an ultimate vacuum of 1 × 10⁻⁴ Torr. It also carries CSA approval, making it suitable for North American laboratory and industrial use.
Built with Welch’s legendary DuoSeal two-stage rotary vane technology, the 1405B-80 features a rugged belt drive system that operates at low RPM for cooler running temperatures, reduced wear, and significantly longer service life compared to direct drive pumps. The large oil reservoir provides excellent vapor tolerance and helps protect the pump from contamination.
