Welch 1400 DuoSeal Unmounted Pump
The Welch 1400 DuoSeal Unmounted Vacuum Pump is the bare pump head designed for custom installations or as a drop-in replacement. This compact two-stage rotary vane belt-drive pump delivers 0.9 CFM (25 L/min) free air displacement and an ultimate vacuum of 1×10⁻⁴ Torr. Its slow 580 RPM operation runs cooler, reduces wear, and extends oil life dramatically compared to direct-drive pumps. Ideal for Schlenk lines, small freeze dryers, degassing, and laboratory vacuum systems. Large oil reservoir helps dilute contaminants.
Note: Motor, base, belt, and pulley sold separately. For a complete turnkey unit, see the 1400B-01 model.
