The Welch 1400N Chemstar Belt Drive Rotary Vane are durable vacuum pumps with a superior vapor handling capability, primarily for pumping corrosive gasses, designed to tolerate harsh chemical contamination with parts corrosion resistant. The 1400N Chemstar Vacuum Pumps use Welch DIrectTorr Gold oil, a synthetic pump oil designed to resist chemical attack. The Welch 1400N Chemstar Belt Drive dual stage rotary vane mechanical vacuum pump offers an excellent ultimate pressure of 1x10 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 corrosive chemical vacuum processes.

The Welch 1402N Chemstar Belt Drive Rotary Vane is a durable vacuum pump with a superior vapor handling capability, primarily for pumping corrosive gasses. The Welch 1402N Chemstar Belt Drive dual stage rotary vane mechanical vacuum pump 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 corrosive chemical vacuum processes. This unique Welch 1402N CHEMSTAR vacuum pump was designed to give you the maximum possible service life when evacuating corrosive gases. However, corrosive gases can cause damage to the most rugged vacuum pump in an improperly configured or improperly operated vacuum system. Please refer to the recommendations made in the
