The Welch 1400 vacuum pump is a two-stage belt-drive pump with a free air displacement of .9 cfm and a ultimate total pressure of 1 x 10-4 Torr. These pumps are designed to be durable and rugged. DuoSeal 1400 pumps have a high contamination tolerance due to their large oil reservoirs which dilute contaminants. A low pump RPM reduces friction and contributes to a long service life for these pumps.
The Welch 1400 is a rotary vane mechanical vacuum pump with excellent vapor handling capability. It is reliable and commonly used in vacuum processes, degassing, freeze drying, vacuum furnace applications.
REBUILT OR REMANUFACTURED Welch 1400 VACUUM PUMPS:
All pump rebuild prices include disassembly, inspection & cleaning. Replacement of seals, gasket, springs, o-rings & valves. Additional parts may be replaced as required upon approval for an extra charge. After the parts are replaced, pumps are tested & painted.
