Welch™ DuoSeal™ High-Vacuum Pumps
Rugged, durable pumps are ideal for demanding applications such as Schlenk drying lines, freeze drying, vacuum distillations, concentrating and degassing
Manufacturer: Welch™ 1399B80
The ruggedness is a result of reduced frictional wear (less than 580rpm vs. typical 1750rpm direct-drive pumps) and high contamination tolerance (contaminants diluted due to large oil capacity).
- Dual-voltage models come wired for lowest voltage listed in specifications chart; may be converted to higher voltage listed by rewiring
- Wiring diagram supplied with each model
