The Welch 8905C-02 Direct Drive vacuum pump is a robust vacuum pump for applications requiring pressures < 50 Torr. The 8905C-02 achieves < 0.050 Torr with a pumping speed of 43 liters/min 230v 50 Hz for European wiring.
These Welch 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. Please consult your Chemtech Scientific Representative for consultation, should the ultimate pressure of your process run above 50 Torr.
