The T2 Rotary Lobe Pump as Turbine (PaT) is an in-pipe systemthat combines pressure and fluid control with electricity generation to recover the embedded energy in pressurisedWater mains or systems.

Water Supply SystemsDamping excess pressures in systems

Balancing pressures in supply networks

Extraction of excess pressure at the outlet of a water supply line

Extraction of Hydro Energy from Natural Resources

Reservoirs or Dams using the spill andcompensation flowsHydro recovery systems from rivers or streamsCanal and lock systems

Water Mills

Industrial ApplicationsPressure damping in cooling watercirculation systemsPumped Storage

Reduction of process water pressure

Lower initial cost when compared to traditional turbines

Utilises standard and field proven products

Simple and robust constructionAvailability of spares coupled with ease of maintenance

High efficiency (up to 86%)

24 hour energy supply

Return on investment period is short when compared to other renewable energy methodsShort delivery time, easily transported and installed with minimal civils works

The energy is recovered from the pressure differential (head) whilst the water flow is passed back into the existing system.

The Pump as Turbine (PaT) can be used to generate electricity for exporting to the grid or be directed for local supply.
