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
Motivation:
- 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.
Ideas:
- 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
