Your advantages
Wilo-Flumen EXCEL-TRE 90-2

Operationally reliable mixing, non-susceptible to clogging, of various kinds of wastewater and sludge in wastewater treatment

The highly efficient Wilo-Flumen EXCEL-TRE 50-3/60-3 series ensure operationally reliable continuous operation or control mode that is non-susceptible to clogging when mixing various kinds of wastewater and sludge in wastewater and sludge treatment.

Recommended services


Your advantages

  • Reliable continuous operation thanks to propellers that are non-susceptible to clogging and largely dimensioned gear bearings
  • High operational reliability by using stainless steel investment-cast propellers
  • Reduction of energy costs due to best thrust to power ratio possible thanks to optimised hydraulics with minimum cavitation tendency and standard-equipped IE3 motor
  • Customer-specific configuration taking into account the system parameters
  • Simple adaptation to the load cases due to operation with a frequency converter
  • Simple installation and removal, even when the basins are filled, thanks to an extensive accessories portfolio
  • Simple replacement due to adaptation to existing installations

Construction

Propeller

2- or 3-bladed propeller made of solid or composite material. Nominal propeller diameter of 500 mm to 900 mm 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 10 m (33 ft) long as standard.

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-chamberThe 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 chamberThe 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 chamberThe 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

Single-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.
