RP's Vertical Turbine Generators are actually reverse running pumps. When the flow that runs through the pump is reversed, the impeller starts turning in the other direction and the pump operates as a turbine.

Operation limits

Capacity up to 6,626 m³/h (29,174 gpm)
Head to 1,067 m (3,500 ft)
Maximum Pressure up to 105 bar (1,523 psi)
Temperature -185 °C to 121 °C (-300 °F to 250 °F)
Applications Hydroelectric generators, Industrial systems, Water transportation systems, Dams, Reverse osmosis, Oil supply systems, Chemical & Petrochemical processes, Cryogenic closed systems


The motor that drives the pump can work also as a generator; when it's working as a turbine, it collects the mechanical energy and transforms it into electricity. The VTG is particularly suited to where the head and flow are consistent, and its main purpose is to fill small hydroelectric needs.

The VTG is available for Cryogenic Closed Systems applications.
