Leybold TURBOVAC MAG 340 M Turbomolecular Pump

The Leybold TURBOVAC MAG 340 M (Part Number 85583) is a high-performance, magnetically levitated turbomolecular vacuum pump engineered for clean, hydrocarbon-free ultra-high vacuum (UHV) generation.

Utilizing a 5-axis active magnetic bearing system, the MAG 340 M suspends the rotor in a frictionless magnetic field, eliminating mechanical contact, wear, and oil lubrication from the vacuum chamber. This configuration provides maintenance-free performance, extremely low vibration, and versatile mounting orientations.

Configured with a DN 100 ISO-K inlet flange, this standard "M" variant is optimized for clean-gas analytical instrumentation, mass spectrometry, electron microscopy, and research applications.

Key Features & Benefits

• 5-Axis Active Magnetic Levitation: Frictionless, contact-free rotor suspension eliminates mechanical wear and minimizes operational vibration.

• 100% Oil-Free Operation: Eliminates oil contamination risk for sensitive analytical and optical vacuum chambers.

• Standard Clean-Gas Application ("M" Series): Designed for high-purity, non-corrosive gas pumping in research and analytical setups.

• Flexible Installation: Frictionless bearing design allows mounting in any orientation without oil-level constraints.

• Integrated Safety System: Equipped with internal emergency mechanical touch-down bearings for safe rotor deceleration during sudden power losses.
