Description/design
Propeller
2- or 3-bladed propeller in sandwich-style construction with a nominal propeller diameter of 1200 mm to
2600 mm.
TRE 312: 2-blade, solid-material propeller with a nominal
propeller diameter of 1200 mm.
Submersible mixers
Submersible mixers with two-stage planetary gear
All propellers have an entwining-free design made possibly
by backward-curved flow edge.
Motor
Wilo-submersible motor of the T-series with standard
connection for an easy and efficient adaptation of the motor output. 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.
TRE units are equipped with the high-efficiency TE motor, which meets the IE3 classification (derived from
IEC 60034‑30).
Seal
Sealing is achieved through the use of a 3-chamber system
(pre-chamber, gear chamber and sealing chamber). The
large-volume pre-chamber and sealing chamber collect
leakage from the mechanical seal. If desired, the prechamber can be equipped with an external sealing chamber electrode. The sealing between the fluid and the prechamber, as well as between the gear and sealing chamber
are realized by a corrosion-resistant and wear-proof
mechanical seal made of solid silicon carbide material. The
sealing between the pre-chamber and gear chamber as
well as between the sealing chamber and motor are realised by radial sealing rings. A seal bushing ensures longterm corrosion-protected fit of the mechanical seal.
Gear
2-stage planetary gear with exchangeable transmissions.
The gear bearings are dimensioned so that the resulting
mixing forces are absorbed and are not transferred to the
motor bearings.
Cable
The power cable is a type NSSHÖU cable for heavy mechanical loads. The power cable enters the motor housing
through a water pressure-tight cable inlet with strain relief
and bend protection. The individual wires as well as the
cable sheath are additionally sealed to keep out fluids.
Options
ƒƒ Special voltages
ƒƒ PTC thermistor sensor
ƒƒ External sealing chamber control
ƒƒ Ceram coating C0
ƒƒ Ex-rated to ATEX or FM
Scope of delivery
ƒƒ Submersible mixer with cable per customer request
ƒƒ TR 212 and TRE 312: Propeller completely pre-assembled
ƒƒ TR(E) 216, 221, 226-3, 316, 321 and 326-3: Propeller
blades - delivered loose, installation on-site
ƒƒ Accessories according to customer request
ƒƒ Operating and maintenance manual
A separate configuration must be carried out for each application to ensure optimum generation of fluid current.
Carefully follow the instructions for the supplied configuration when installing the units.
Accessories
ƒƒ Stand for free positioning of the units in the basin
ƒƒ Auxiliary lifting device
ƒƒ Special fastening pieces for the use of an auxiliary lifting
device for multiple units
ƒƒ Additional rope anchoring
ƒƒ Fixation sets with anchor bolts
Commissioning
Immersed operating mode S1:
The unit can be used immersed in permanent operation.
Surfacing the propeller or motor is strictly prohibited. In
the case of fluctuating fluid levels, the system should
switch off automatically if the degree of water submersion
drops below the minimum level.
When installing the power cables, make sure that they are
not drawn into the propeller by the fluid current.

The value P1.1 corresponds to the electrical power consumption at the duty point. P1 refers to the max. electrical power consumption.
All of the data applies to 3~400 V, 50 Hz and a density of 1 kg/dm3.
Thrust and power measured in accordance with ISO 21630; thrust and power values vary for mixers with Ceram propeller coatings.
