Wilo-Flumen OPTI-TR ...
Surface-cooled submersible motor in three-phase current design with permanently
lubricated und large-size rolling bearings. The motor winding is equipped with temper-
ature monitoring. The motor heat is given off directly to the surrounding fluid via the
motor housing. The connection cable is designed for heavy mechanical loads, sealed
water pressure-tight against the fluid and is sealed longitudinally watertight. The con-
nection cable has bare cable ends and is 10 m (33 ft) long as standard.
