Product Details

  • Deep Vacuum

  • Vacuum to 1 X 10-4 torr

Common Applications:

Centrifugal Concentrators, Vacuum Ovens, Freeze Dryers, SEM's, Annular Spaces / Transfer Lines

The Welch 8905A Direct Drive vacuum pump is a robust vacuum pump for applications requiring pressures < 50 Torr. The  8905A achieves < 0.050 Torr with a pumping speed of 51 liters/min (1.8 CFM).

These small direct drive, oil sealed vacuum pumps should not be operated continuously at pressures above 50 Torr. Operating this vacuum pump at higher pressure will induce excessive oil spraying from the exhaust of the vacuum pump causing premature failure and void warranty.
