Wilo-Flumen EXCEL-TRP 216… – TRP 326…
Maximum thrust with minimum energy input – for targeted basin flow.
The Wilo-Flumen EXCEL-TRP mixer ensures even and energy-efficient distribution of the activated sludge in your basin. The combination of powerful permanent magnet motors and durable Wilo propellers with self-cleaning effect guarantees a deposit- and clogging-free flow – even at high thrust values. As an option, the mixer can be equipped with cutting-edge monitoring technology and sensors so that you can always keep an eye on the operating status.

Construction
Propeller
2- or 3-bladed propeller made of solid or composite material with a nominal propeller diameter of 1200 mm to 2600 mm. Clogging-free propeller geometry design made possible by backward-curved incoming flow edge.
Motor
Three-phase current version of a surface-cooled permanent magnet submersible motor with permanently lubricated and generously dimensioned 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 pressure watertight against the fluid and is sealed longitudinally watertight. The connection cable has bare cable ends and is 10 m (33 ft) long as standard.
The permanent magnet submersible motor fulfils the IE5 motor efficiency class (based on IEC 60034-30-2).
Gear
Two-stage planetary gear with exchangeable transmission. Gear bearings have been dimensioned large to absorb resulting stirring forces and not transfer these to the motor bearing.
Seal
The system is sealed by a 3-chamber system:
- Pre-chamber
- Gear chamber
- Sealing chamber
Pre-chamber
The high-volume pre-chamber has been filled with gear oil to absorb any leakage at the seal on the fluid side. A mechanical seal is used as the seal on the fluid side. A rotary shaft seal seals towards the gear chamber.
Gear chamber
The gear chamber has been filled with gear oil to guarantee continuous lubrication of the planetary gear and the gear bearings. A mechanical seal seals towards the sealing chamber.
Sealing chamber
The high-volume sealing chamber is filled with white oil and absorbs any leakage from the gear chamber. A rotary shaft seal seals towards the motor.
