Manufacturer: Welch Pumps
Now every Welch 1400 pump we sell comes complete with a Welch 1417 oil mist exhaust filter.
The Welch DuoSeal vacuum pumps are known for their ruggedness world-wide. These pumps have large oil reservoirs to dilute contaminants. Low pump rpm 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.

The Welch 1400 DuoSeal is a two-stage, oil-sealed rotary vane pump for work that needs a deep vacuum, well below 1 Torr. The pulley drive keeps the pump turning slowly, at 580 rpm, which means less friction, cooler oil and slower oil breakdown, so the pump keeps its performance between oil changes.
In the lab it is a natural fit for Schlenk drying lines, freeze dryers, vacuum ovens, degassing and short path or other high-boiling distillations. Pair it with a cold trap: the trap catches solvent before it reaches the oil, protects the pump and helps it reach a deeper vacuum.
Plan your process around the pump's strengths. A two-stage oil-sealed pump should not run continuously above 1 Torr, because running at higher pressure drives oil mist out of the exhaust. The included 1417 exhaust filter catches that mist, and the gas ballast helps clear water vapour from the oil.

Wayne there has an excellent store, he has everything, really nice stuff at good prices, ultimately very fair compared to others. I will certainly be going back for everything I need. Got some things from a different place and spent 50% more, just go see Wayne first, he seems like he wants to help you out more than sell you out the door.
