THE SPJ AS A MAIN PROPULSION UNIT FOR EXTREME CONDITIONS
As a main propulsion unit for coasters and inland vessels, the SCHOTTEL Pump-Jet gives reliable service wherever conventional propeller drives cannot be used due to restricted draught. With its compact design, low buoyancy loss and low suction, the SPJ generates high thrust in any direction desired – even in extremely shallow waters. Like all SCHOTTEL products, it offers very smooth operation and excellent manoeuvring characteristics.

OPERATION PRINCIPLE

Contrary to a conventional propeller with a fixed pitch, blades can be rotated around their axis and change their pitches variably and stagelessly from zero thrust to headway or reversing. Advanced calculation methods allow the SCP to be optimally adjusted to the hydrodynamic conditions on the vessel’s hull, thereby maximizing efficiency and minimizing noise generation.

SCD Twin
COMPACT, MAINTENANCE-FRIENDLY DESIGN
In contrast with other commercially available systems, in which the electric motor is housed in an underwater pod that is overdimensioned for this purpose, the motor in the SCD is vertically integrated into the support tube of the thruster and thus inside the vessel.

NAV SOUND-PROOF
The sound-proof version consists of an enclosed, insulated canopy, thereby reducing the level of air-borne noise to a mere of about 80 dB(A) at a distance of one metre.
