Used PFEIFFER / BALZERS TPH 450H #293765864 for sale

PFEIFFER / BALZERS TPH 450H is a high-performance turbomolecular pump renowned for its exceptional capabilities in creating and maintaining high vacuum levels in a wide range of applications. This pump is a product of BALZERS Vacuum, a leading provider of vacuum solutions for various industries including semiconductor, analytics, and research. BALZERS TPH 450H model is part of the TPH series, which is known for its reliability, efficiency, and robust design. At the core of PFEIFFER TPH 450H is a turbomolecular rotor that operates on the principle of kinetic energy to achieve high pumping speeds and low ultimate pressures. The rotor consists of multiple blades that rotate at high speeds, typically in the range of tens of thousands of revolutions per minute. This rotational motion creates a high-speed gas flow within the pump, effectively removing gas molecules from the equipment and creating vacuum conditions. TPH 450H pump features a hybrid bearing system that combines the benefits of magnetic and ball bearings, providing both high performance and extended service life. The use of a magnetic bearing unit reduces friction, minimizes mechanical wear, and eliminates the need for lubrication, resulting in a cleaner vacuum environment and reduced maintenance requirements. The ball bearings support the rotor during the initial start-up phase and provide additional stability during operation. One of the key features of PFEIFFER / BALZERS TPH 450H is its high pumping speed, which is the rate at which the pump can remove gas molecules from the machine. BALZERS TPH 450H is capable of achieving pumping speeds in the range of 450 liters per second, making it suitable for demanding applications that require rapid evacuation of gas from the tool. This high pumping speed ensures quick pump-down times and efficient processing of gases in vacuum systems. The ultimate pressure of PFEIFFER TPH 450H refers to the lowest pressure that can be achieved in the asset when the pump is in operation. This parameter is critical in applications where high vacuum levels are required to maintain the desired conditions for processes such as thin film deposition, surface analysis, and particle accelerators. TPH 450H pump can achieve ultimate pressures in the range of 10^-10 mbar, indicating its capability to create and maintain ultra-high vacuum conditions. In terms of design and construction, PFEIFFER / BALZERS TPH 450H features a compact and modular layout that allows for easy integration into vacuum systems. The pump is equipped with a dedicated control unit that enables precise monitoring and adjustment of key parameters such as rotational speed, bearing temperature, and vibration levels. The control unit also provides diagnostic information and alarms to alert users of any potential issues or maintenance requirements. Overall, BALZERS TPH 450H is a versatile and reliable turbomolecular pump that offers high performance, efficiency, and durability in a wide range of vacuum applications. Its advanced design, high pumping speed, and low ultimate pressure make it an ideal choice for demanding research, industrial, and analytical processes that require precise vacuum conditions.
