The turbomolecular pumps from Leybold generate a clean high and ultra-high vacuum, are easy to operate and are exceptionally reliable. In connection with a well rated backing pump, pressures below 10-10 mbar (0.75 x 10-10 Torr) can be attained.
Leybold offers two product lines:
1. TURBOVAC line Turbomolecular pumps with mechanical rotor suspension 2. TURBOVAC MAG line Turbomolecular pumps with magnetic rotor suspension Each of the two product lines contains “classic” turbomolecular pumps as well as turbomolecular pumps with a compound stage. Leybold is one of the world’s leading manufacturer of turbomolecular pumps. Consequently, the TURBOVAC and the TURBOVAC MAG pumps are successfully used in many applications. A list of the most important ones is given in the table “Applications” in the section “General”.
Principle of Operation The turbomolecular pump is a turbine with blades. By the momentum transfer from the rapidly rotating rotor blades to the gas molecules their initially non-directed thermal motion is changed to a directed motion.
