Welch 1402B-01 Duoseal Vacuum Pump, Welch (CAT#: STEM-GLE-0589-LGZ)

The manufacturer of Welch 1402B-01 Duoseal Vacuum Pump is Welch. Model is 1402B-01. DuoSeal vacuum pumps are rugged. These rotary vane pumps have large oil reservoirs to dilute contaminants. The pump speed is low, friction and wear are reduced, while the reservoir temperature is lowered, the chemical reactivity is reduced. The pump can be ordered with an optional exhaust filter to control oil mist.

1. Is sturdy and durable.
2. Applicable for pressure required and less than 1 Torr.
3. The 1402B-01 achieves < 0.001 Torr with a pumping speed of 160 liters/min (5.6 CFM).
4. The secondary oil-sealed vacuum pump should not operate continuously at pressures above 1 Torr. Running this vacuum pump at higher pressures will cause the vacuum pump exhaust to overspray, causing premature failure and voiding the warranty.
