Turbos
LEYBOLD:
The TURBOVAC models 50 to 1000 are turbomolecular pumps featuring grease-lubricated bearings. These units are engineered to pump vacuum chambers down to pressures in the high-vacuum range. A TURBOTRONIK frequency converter and a forevacuum pump are required for the operation of the TURBOVAC. These units are not suitable for operation without a forevacuum pump. Turbomolecular pumps are not suitable for pumping either gases which contain dust particles or liquids. Turbomolecular pumps without a purge gas feature are suitable only for moving air or inert gases. They are not suitable for pumping aggressive or reactive gases. TURBOVAC versions identified with a “C” in the model number are equipped with this purge gas feature, it protects only the bearing area and the motor in the TURBOVAC. Some media (such as aluminum trichloride) can sublime inside the pump and form deposits. Thick deposits reduce the play between moving parts to the point that the pump could seize. In some processes deposits can be prevented by heating the pump. Please consult with us in case such problems arise. Corrosive gases (such as chlorine) can destroy the rotors. During operation the pressure inside the TURBOVAC is so low that there is no danger of ignition (at pressures below about 100 mbar, 75 Torr). A hazardous condition will be created if flammable mixtures enter the hot pump at pressures above 100 mbar (75 Torr). During operation the pump can reach temperatures as high as 120°C (248 °F). Sparks could occur in case of damage to the pump and these could ignite explosive mixtures. We would be glad to consult with you as regards the media which can safely be handled with this unit.
