What is an impeller?

An Impeller is a rotor that is used to increase the flow and pressure of a fluid. It's the opposite of a turbine which decreases and extracts energy from flowing fluids. Impellers are used in in example centrifugal compressors, agitated tanks and air pumps.

Dimensionally accurate impeller manufacturing 

The manufacturing of dimensionally accurate impellers is possible thanks to our modern machine centers and our long experience.  One of many things that has enabled our cost-effective manufacturing of impellers is the usage of 5-axis machining.  As a rule, we manufacture impellers in serial production, which is based on the production of a prototype, but individual machining may also be possible.

We have served many satisfied customers both in Finland and internationally from different industrial sectors, which include e.g. aircraft, automotive, food and marine industries. You can view some of the parts we manufacture in our references.
