Advantages to you
Wilo-EMU TRE 312

Your advantages

  • 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.

Construction

Propeller

2- or 3-bladed propeller made of solid or composite material. Nominal propeller diameter of 20 in to 47 in with clogging-free propeller geometry.

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 40 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.

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.

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.
