2- or 3-bladed propeller with a nominal propeller diameter of 220 mm to 400 mm. Clogging-free construction thanks to backward-curved incoming flow edge and patented helix hub.


Submersible motor of the T-series (surface-cooled motor) with standard connection for an easy and efficient adaptation of the motor power. The motor heat is given off directly to the fluid via the housing. The winding is equipped with a temperature monitor. Large-sized inclined and grooved ball bearings ensure long service life of the motor bearings.


Double shaft sealing with large-volume sealing chamber to collect leakage from the mechanical seal; available with external pencil electrode on request. On the fluid side, a corrosion- and wear-resistant mechanical seal made of solid silicon carbide material is used; on the motor side, a rotary shaft seal is used. On TR 36 / TR 40 types, a seal bushing ensures long-term corrosion-protected fit of the mechanical seal.


Longitudinally watertight connection cable type NSSHÖU for strong mechanical loads. The connection cable enters the motor housing through a water pressure-tight cable inlet with strain relief and bend protection.
