An economic concept

The “propeller-pump” is made of a stator assembly, a specific nozzle and a rotor.

Compared to a conventional propeller, the “propeller-pump” concept delivers an average propeller efficiency 15% higher, with a diameter 20 to 30% less.

The nozzle drives the water and the stator makes the watter rotate and come more quickly on the whole propeller area.

This process leads consequently to a decrease of the wake effect on the propeller.
