Description

All high vacuum pumps rebuilt and sold through AVAC have been completely disassembled, cleaned, re-machined and carefully inspected for wear by our factory-trained technicians. Units are assembled with new vanes, shaft seals, exhaust valves, gaskets, springs, oil distribution valves and bearings prior to undergoing an extended performance test to meet or exceed OEM specifications. All pumps are then painted, detailed, and pass a final quality assurance inspection prior to shipping. A final test certificate is provided with each pump, which will be covered with a one-year warranty.

The Welch 1405 is a tough vacuum pump that can handle a lot of vapor. The 1x10-3 Torr ultimate pressure of the Welch 1405 Mechanical Vacuum Pump is exceptional.

These pumps are usually 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, as well as other vacuum processes.

These Welch 1405 Pumps have a 3.2 CFM pumping speed and operate on 115 VAC.

  • High contamination tolerance
  • Low RPM for long service life
  • Adjustable Vac. / Gas Ballast

DuoSeal Vacuum Pumps are well-known for their toughness all over the world. To dilute contaminants, these pumps have large oil reservoirs. Low pump rpm lowers friction and wear while also lowering reservoir temperature, which lessens chemical reactivity.
