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.

Large-volume sealing chamber with double shaft sealing. The sealing chamber is filled with
white oil and absorbs the leakage from the seal on the fluid side. A corrosion- and wear-re-
sistant mechanical seal is used on the fluid side. The seal on the motor side involves either a
rotary shaft seal or a mechanical seal.
2- or 3-bladed propeller made of solid material with a nominal propeller diameter of
200 mm to 400 mm. Clogging-free propeller geometry design made possible by backward-
curved incoming flow edge.
