Turbomolecular Vacuum Pump
The Modular Turbo Pumping Station for Clean Vacuum
A turbomolecular vacuum pump is a specific type of vacuum pump, similar to a turbopump, used to obtain and maintain high vacuum pressure. Turbomolecular vacuum pumps work on the principle that gas molecules can be given momentum in the desired direction by colliding with a moving solid surface. In a turbomolecular vacuum pump, a rapidly spinning fan rotor 'hits' gas molecules from the inlet of the pump pressure towards the exhaust in order to create or maintain a vacuum pump pressure and speed.
The Operating Principles of a Turbomolecular Vacuum Pump and Pumping Speeds
The pumping effect of a turbomolecular vacuum pump consists of blades that are based upon the transfer of impulses from the rotating blades to the gas molecules being pumped. A Turbomolecular vacuum pump has molecules that collide with the blades that are adsorbed and leave the blades again after a certain period of time. The compression ratio in this process, blade speed is added to the thermal molecular speed. To ensure that the speed component of a turbomolecular vacuum pump that is transferred by the blades is not lost with other molecules, the molecular flow must be available within the pump, meaning the free path must be greater than the blade spacing distance within the turbomolecular vacuum pump.
The turbomolecular vacuum pump works on the aspect that gas molecules when hit by a solid surface, will move in a specific direction. The turbomolecular vacuum pump consists of working parts that are not similar to a multi-bladed turbine, with blades along the whole length of the shaft within the turbomolecular vacuum pump creating pumping pressure for the molecular speed.

What are the applications of Turbomolecular Pumps?
Turbomolecular pumps are utilized in a variety of high and ultra-high vacuum applications, including both clean (e.g., in analytical equipment or R&D) and highly harsh applications in the semiconductor industry, where the pumps must handle corrosive gases or sensitive process conditions. The best TMP design for each application must be chosen based on the application's requirements. It's vital to remember that each design (different pumping mechanisms, bearing designs, etc) will have advantages and disadvantages that will decide its suitability for a specific application.
