Construction

Propeller

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.

Motor

Surface-cooled submersible motor in three-phase current design with permanently lubricated 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 housing. 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.

Seal

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-resistant mechanical seal is used on the fluid side. The seal on the motor side involves either a rotary shaft seal or a mechanical seal.
