* = high wear-resistant propeller made of composite PUR/GFK (PUR/GFRP) material
featuring 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 di-
mensioned roller bearings. The motor is cooled by the fluid around it. 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 lon-
gitudinally watertight. The connection cable has bare cable ends and the standard
length is 10 m (33 ft). Longer cables are available on request.

Housing material
Between the motor and propeller, there is the seal housing with the seal on the fluid
and on the motor side. The seal on the fluid side is provided by a mechanical seal. The
seal on the motor side involves either a rotary shaft seal or a mechanical seal. The seal
housing is filled with white oil and absorbs leakage from the seal on the fluid side.
