The Welch 8920C-01 Direct Drive vacuum pump is a robust vacuum pump for applications requiring pressures < 1 Torr. The 8920C-01 achieves < 0.001 Torr with a pumping speed of 218 liters/min (7.7 CFM).
Two stage, oil sealed vacuum pumps should not be operated continuously at pressures above 1 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. Please consult your Chemtech Scientific Representative for consultation, should the ultimate pressure of your process run above 1 Torr.
