SPJ Pump Jet
An impeller sucks in water through the intake funnel, a protective grid in the bottom plate preventing foreign bodies from entering the Pump-Jet.
The impeller forces the energized water into a diffuser, as a result of which kinetic energy is converted into pressure energy.
This energy transformation process is continued in the diffuser, and the water is collected in the pressure casing.
The water is finally expelled through the outlet nozzles at an angle of 15°, and thrust is generated which can be steered through 360°.
