The Welch DuoSeal vacuum pumps are known for their ruggedness world-wide. These pumps have large oil reservoirs to dilute contaminants. Low pump rpm to reduces friction and wear while minimizing reservoir temperature to lessen chemical reactivity.
The Welch 1400 DuoSeal belt drive rotary vane is a durable vacuum pump with a superior vapor handling capability. It offers an excellent ultimate pressure of 1x10-4 torr. These pumps are commonly used for vacuum furnace evacuation, backing turbomolecular pumps, backing diffusion pumps, rotary evaporation, refrigeration system evacuation, epoxy degassing, vacuum sterilization, backing mass spectrometers, freeze drying, vacuum centrifugal applications, vacuum distillation, space research, and other vacuum processes. These Welch 1400 DuoSeal Belt Drive Pumps have a pumping speed displacement of 0.9 CFM.
