Wilo-EMU TR 216… – TR(E) 326…
- Efficient energy usage. The innovative blade geometry and energy-efficient IE3/IE4 motors ensure the best possible specific thrust coefficient. At the same time, this reduces your energy and operating costs.
- Consistently reliable. The low-wearing GFK/PA6 propeller is durable and scores with its self-cleaning effect.
- Smooth running thanks to the balanced propeller load, even in high thrust ranges and when incoming flow conditions are unfavourable.
Low-speed submersible mixer with two-stage planetary gear, in continuous or intermittent operation.

2- or 3-bladed propeller made of solid or composite material. Nominal propeller diameter of 500 mm to 1200 mm with clogging-free propeller geometry.
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.
EMU TRE models:
The submersible motor meets the IE3/IE4 motor efficiency class (according to IEC 60034-30). Motors of the motor efficiency class “IE4” have been specified as “E4” in the motor designation.
The system is sealed by a 3-chamber system:
- Gear chamber
- Sealing 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.
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.
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.
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.
