Turbomolecular Vacuum Pump

The Modular Turbo Pumping Station for Clean Vacuum

A turbomolecular pump is a specific type of vacuum pump, similar to a turbopump, used to obtain and maintain high vacuum pressure. Turbomolecular 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 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 Turbo Pumps and Pumping Speeds


The pumping effect of an turbomolecular vacuum consists of blades that are based upon the transfer of impulses from the rotating blades to the gas molecules being pumped. Turbopumps have 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 that is transferred by the blades is not lost with other molecules, molecular flow must be available within the pump,meaning the free path must be greater than the blade spacing distance within the turbomolecular pump.

Turbomolecular pump works on the aspect that gas molecules when hit by a solid surface, they will move in a specific direction.The turbo pumps consist of working parts that are not similar to a multi-bladed turbine, with blades along the whole length of the shaft within the turbomolecular pumps creating pumping pressure for the molecular speed.

Turbomolecular pumps such as the HiCube turbo pumping stations, we have developed the perfect turbomolecular vacuum pump solution for your applications in the fields of research and development, accelerators, analytics and surface physics, as well as vacuum process technology and general vacuum applications.

Thanks to the modular design principle, we can offer you never-before-seen versatility with the turbomolecular vacuum pump HiCube series that satisfies the widest range of requirements in the pumping speed range from 35 l/s to 685 l/s. Turbopump and backing pump are matched perfectly to one another: “Plug and Play”, the way you want it.

What’s so special about the HiCube vacuum solution: The combination of a turbopump from the HiPace series and a backing pump designed for the user’s specific application needs. We offer you the HiCube in Pro and Classic versions; available with dry compressing or oil-sealed backing pump and an ultimate pressure of up to 5 · 10-10 hPa.
