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