maintenance. Due to the magnetic design, there is no risk of zone
entrainment. Compared to pumps with shaft seals, the OktaLine's
magnetic coupling achieves up to 20 % lower operating costs and
considerably reduced maintenance costs.
Pfeiffer Vacuum's Hi-Quad mass spectrometer system incorporates
a 2-filament cross-beam ion system with a guiding magnet, representing
another integration of magnetic technology in its products.
Basically, the design of the turbopump is similar to that of a turbine,
explains Pfeiffer: " Inside the pump, several rotor disks are
mounted on a shaft. Between them are stator disks whose blade
orientation is mirror-inverted to that of the rotor blades. As a result,
the gas molecules to be pumped are conveyed from the highvacuum
flange along the individual turbo stages to the fore-vacuum
flange. The rotor of the turbopump is driven by a brushless
three-phase synchronous motor. This enables very high rotational
frequencies of up to 1500 Hz to be achieved. The rotor shaft
bearing, in turn, consists of a permanent magnet bearing on the
high vacuum side and a high-performance ball bearing on the fore

vacuum side. Although the ball bearing is minimally lubricated, the
pump generates an oil-free vacuum. " For a full presentation about
the turbopump, see www.pfeiffer-vacuum.com.
