- Ultimate vacuum <0.001 Torr
- Low RPM for long service life
Description
The Welch 1400B-01 DuoSeal Vacuum Pump is a rugged and robust vacuum pump for applications requiring pressures < 1 Torr. The Welch vacuum pump 1400B-01 achieves < 0.001 Torr with a pumping speed of 25 liters/min (0.9 CFM). Rugged oil-seal pumps for a wide variety of vacuum needs, including Schlenk drying lines, freeze drying, degassing, concentrations, distillations, and more. Pulley drive enables low pump rpm operation – reduces friction, oil temperature, and oil degradation. Large oil reservoir minimizes contamination effects and extends maintenance intervals. Use of a cold trap is recommended to protect the pump and enhance vacuum levels. Two stage, oil sealed vacuum pumps should not be operated continuously at pressures above 1 Torr. Operating this DUOSEAL pump at higher pressure will induce excessive oil spraying from the exhaust of the vacuum pump causing premature failure and void warranty.
