Leybold Heraeus TURBOVAC TMP-50 TURBO Molecular High Vacuum Pump 85406 Air Cooling. Leybold Heraeus NT 50 85403 Controller. New Old Stock; These units have recently been tested and are working perfectly. Photo 10 shows a working connection with a Forepump, which is necessary – in this case it’s an Alcatel M2008A Forepump. Photo 11 shows the torr meter, demonstrating that the Turbovac has created a vacuum. Photo 12 shows the meter working. The TURBOVAC TMP50 / PN 85399 and 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 NT 10 frequency converter and a forevacuum pump are required for the operation of the TURBOVAC TMP-50. These Leybold TMP 50 Turbo Pumps are not suitable for operation without a forepump. Leybold TMP50 Turbomolecular pumps are not suitable for pumping either gases which contain dust particles or liquids. Turbovac 50Turbomolecular 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. Leybold TURBOVAC TMP 50 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 TMP 50 turbo pump 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. Pumping Speed for N2 (l/sec): 55. Ultimate Pressure (mbar): 8 x 10-9.
