Leybold TURBOVAC MAG 340 M Turbomolecular Pump

The Leybold TURBOVAC MAG 340 M (Part Number 89487) is a high-performance, magnetically levitated turbomolecular vacuum pump engineered for hydrocarbon-free, ultra-clean high and ultra-high vacuum (UHV) applications. Featuring a 5-axis active magnetic bearing system, the MAG 340 M operates completely frictionless, eliminating mechanical wear and the need for oil or grease lubrication.

Equipped with a DN 160 ISO-K high-vacuum inlet flange, this unit is ideal for analytical instruments, semiconductor processes, surface analysis, mass spectrometry, and high-purity research environments requiring low vibration and zero oil contamination.

Key Features & Benefits

• 100% Oil-Free Operation: Active magnetic levitation eliminates bearing grease and oil completely, preventing backstreaming and ensuring clean UHV conditions.

• Zero Mechanical Wear: Non-contact magnetic bearings drastically reduce maintenance requirements and extend service intervals.

• Ultra-Low Vibration & Noise: Ideal for vibration-sensitive equipment like electron microscopes and precision mass spectrometers.

• High Pumping Speed & Compression: Delivers efficient pump-down times and exceptional compression ratios for light gases like Helium and Hydrogen.

• Flexible Mounting: Can be installed in any orientation without risk of bearing damage.
