Turbo-Molecular Pumps

Turbo molecular pumps are used in scientific and research applications, such as mass spectroscopy, and in manufacturing, such as silicon chip production.  They are based on a multi-stage axial flow design,.effectively a gas turbine compressor section in reverse, and are driven by electric motors running at speeds up to 90,000 rpm. Despite extensive development since their invention over 70 years ago, the basic blade design in turbo-molecular pumps has remained a simple inefficient profile. Current manufacturing technologies impose significant limitations on performance and end user customers comment that current turbo pumps tend to be noisy, suffer from vibration and have a short life.  
The Bladon Jets blade-forming technology, enabling complex shaped aerofoil blade profiles, can increase pump efficiency and performance, whilst at the same time reducing size and cost (due to a reduction in the number of stages) and improving reliability (due to a reduction in speed).
