Pfeiffer Vacuum TMH 260 Turbomolecular Pump

The Pfeiffer Vacuum TMH 260 (P/N: PM P02 192) is a highly reliable, compact turbomolecular pump engineered to deliver ultra-clean high-vacuum performance. Featuring a pumping speed of up to 210 L/s for Nitrogen, this pump is an industry workhorse heavily utilized in analytical instrumentation, mass spectrometry, thin-film R&D, and physics research laboratories.

This unit is engineered with Pfeiffer’s proven hybrid bearing system. It pairs a friction-free, permanent magnetic bearing on the high-vacuum side with an oil-lubricated ceramic ball bearing on the forevacuum/backing side. This design minimizes mechanical wear, provides exceptional rotor stability at 60,000 RPM, and cuts acoustic and kinetic vibration down to negligible levels—protecting sensitive laboratory metrology and detector workflows.

Key Features

• Proven Hybrid Bearing System: The combination of a wear-free magnetic top bearing and an oil-lubricated ceramic backing bearing guarantees rapid run-up times and a long operational lifespan.

• Ultra-Low Vibration & Noise: Operates cleanly at $<50\text{ dB(A)}$, making it comfortable and safe for quiet university laboratory benches.

• High Compression Ratios: Delivers crisp ultimate pressure metrics down to the 10−10 mbar range when paired with a clean rotary vane or dry backing pump.

• Rugged and Serviceable: Built with Pfeiffer’s legendary industrial architecture, ensuring straightforward routine maintenance (oil wick/reservoir swaps) for low long-term operating costs.
