* = high wear-resistant propeller made of composite PUR/GFK (PUR/GFRP) material
featuring reinforced leading edge.
Single-stage planetary gear with exchangeable transmissions. Gear bearings have been
dimensioned adequately to absorb resulting stirring forces and not transfer these to the
motor bearing.
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.

* = motors in efficiency class IE4 have been specified as "E4" in the motor designation.
** = depending on the motor type and motor capacity fluid temperatures up to 60 °C
(140 °F) are possible.
The system is sealed by a 3-chamber system:
▪ Pre-chamber
▪ Gear chamber
▪ Sealing chamber
