* = high wear-resistant propeller made of composite PUR/GFK (PUR/GFRP) material featur-
ing reinforced leading edge.
The system is driven by a surface-cooled motor in three-phase current version. The motor is
fitted with maintenance-free, permanently lubricated and appropriately dimensioned roller
bearings. The motor is cooled by the fluid around it. The waste heat is transferred directly to
the fluid via the motor housing.
The connection cable is sealed water pressure-tight against the fluid and is sealed longitu-
dinally watertight. The connection cable has bare cable ends and the standard length is
10 m (33 ft). Longer cables are available on request.
