Used PFEIFFER / BALZERS TMH 262 #9253439 for sale

PFEIFFER / BALZERS TMH 262 is a turbomolecular-based pumping unit that is capable of achieving ultra-high vacuum levels. This device utilizes a two-stage axial flow geometry to compress and accelerate the molecules of the gas it is exposed to. What sets this pumping unit apart from other equipment is its very good pumping speed and high speed, regardless of pressure. BALZERS TMH 262 is equipped with a permanent-magnet based motor-turbine pair and a two-stage compressor, which together are capable of achieving a pumping speed of up to 1,000 liters per second with an ultimate vacuum pressure of only 10-8 mbar. This unit also features a built-in, digitally adjustable mechanical brake, which allows for precise flow rate regulation. The motor and turbine are housed inside the pumping unit's rigid aluminum casing, which also contains the mechanical transmission that connects the two components. This entire assembly is hermetically sealed. The unit weighs only 22.2 kg and measures 492 x 297 x 540 mm, making it small enough to fit in most standard-size laboratories. It comes with an integrated mechatronic control and basic motor-protection unit, which features built-in interlocks, a solid state microprocessor-controlled system, and a fully redundant protection. PFEIFFER TMH 262 also has multiple security levels that ensure the pumping unit will run safely and reliably. For protection against overheating, the unit has an overheating alarm as well as a temperature limiter that will shut the unit off if temperatures exceed set levels. Additionally, a protective coating on the motor ensures longer life, even in harsh conditions. TMH 262 is ideal for applications ranging from medical, industrial, and semiconductor processes to material sciences and research. Its extremely high pumping speed, small size, and low-pressure capabilities make it one of the most reliable and efficient high-vacuum pumps on the market today.
