PAT [Pump As Turbine]

2011 – 2014

During this research program (“Hydrovalys”) the performance improvement and optimization of a typical pump, operated as a turbine was accomplished.

Program main features


  • Minimizing the specific cost per kW of small and mini hydroelectric plants, which is still relatively large.
  • Presenting the utilization of a centrifugal pump as turbine as an alternative solution to lower these costs.


  • Pump works as a turbine when liquid flows in reverse mode.
  • The system can be inserted in pipelines transferring water or other fluids, exploiting the surplus, or rejected kinetic and dynamic energy of the flow.

Key Advantages:

  • Simple construction
  • Αbility to use standard of the shelve components with minimal modifications
  • Βenefit from decentralized electricity generation
  • Cost effective solution for low output applications, such as energy recovery.
  • Apply to a wide range of useful applications:
    • Industrial
    • Building
    • Reverse Osmosis
    • Retrofitting
    • Residual Water Utilization
  • Fast Initial Capital Return
  • Decrease of emissions

Research process & Results
