Pfeiffer Vacuum TMH-260 Turbomolecular Pump with TCP-120 Controller
The Pfeiffer TMH-260 is a precision-engineered turbomolecular pump designed to create the ultra-high vacuum (UHV) environments essential for advanced research and industrial processes. Built with a hybrid bearing system, magnetic bearings on the high-vacuum side and ceramic ball bearings on the forevacuum side, it delivers smooth, low-vibration operation even at rotational speeds reaching 60,000 rpm. The result is stable performance, minimal noise (<50 dB), and long-term reliability across a wide range of high-vacuum applications.
At HiTechTrader, we make cutting-edge vacuum technology like the TMH-260 accessible to laboratories, universities, and industrial facilities by offering rigorously tested pre-owned and refurbished systems. Paired with the Pfeiffer TCP-120 controller, this package ensures precise speed regulation, safe and controlled start-up, built-in thermal and overspeed protection, plus RS232 remote monitoring capability, all at a fraction of the cost of new equipment. This combination is especially valuable for fields such as semiconductor fabrication, mass spectrometry, thin-film deposition, and surface science research, where precision and dependability are critical.
