PRODUCTDESCRIPTION English
Clarication must be sought as to whether the
pump can be used at all with another uid.
2.7. Sound pressure
Dependingonthesizeandperformance(kW)
ofthepump,ithasasound-pressurelevelof
approximately70dB(A)to90dB(A)during
operation.
However,theactualsound-pressurelevel
dependsonseveralfactors.Theseinclude,for
example,theinstallationdepth,installation,
xationofaccessoriesandpiping,thedutypoint,
immersiondepth,etc.
We recommend that the end-user takes an
additional measurement at the workplace once
the pump is running at its duty point and under all
operating conditions.
CAUTION: Wear ear defenders!
According to applicable laws and regula-
tions, ear protection must be worn if the
sound-pressure level is 85dB(A) or more!
Theend-user must make sure that this is
complied with!
2.8. Standards and guidelines used
The pump is subject to various European di-
rectivesandharmonisedstandards.SeetheEC
declaration of conformity for precise information
about these.
Inaddition,variousstandardsareusedasabasis
foroperating,assemblinganddismantlingthe
pump.
2.9. CE marking
TheCEmarkingisattachedtotheratingplate.
3. Product description
The pump is manufactured with great care and is
subject to constant quality controls. Trouble-free
operation is guaranteed if it is installed and main-
tained correctly.
3.1. Intended use and elds of application
ELECTRICAL hazard
When using the pump in swimming pools or
other basins that can be entered, there is a
risk of electrocution. Note the following:
• Use is strictly forbidden if there are people in
the basin!
• If there are no people in the basin, protec-
tive measures must be taken according to
DINVDE0100-702.46 (or the appropriate
national regulations).
DANGER - explosive uids!
It is strictly prohibited to pump explosive u-
ids (gasoline, kerosene, etc.). The pumps are
not designed for these uids!
The Wilo-Drain TMT 32M submersible pumps are
designed for intermittent and permanent pump-
ing of wastewater with solids up to a maximum of
9mminsumpsandtanks.
The submersible pumps must not be used for
pumping:
• Potable water
• Fluidscontaininghardcomponentssuchasstone,
wood,metal,sandetc.
• Highlyammableandexplosiveuidsinpure
form
.
The intended use includes complying with these
instructions. Any other use is considered to be
outside the intended use.
3.2. Set-up
The Wilo-Drain TMT 32M pumps are submersi-
ble drainage pumps that are suitable for vertical
operation in portable wet well installation.

3.2.1. Hydraulics
Rotodynamic hydraulics with half-open
multi-channel impeller and connection on the
pressuresideasahorizontalthreadedange
connection and built-in pump foot.
The hydraulics are not self-priming, in other
words, the uid must ow in either automati-
cally or with supply pressure.
3.2.2. Motor
Inthethree-phasecurrentversion,glanded
motorsareused.Themotoriscooledbytheuid
around it. The waste heat is transferred directly to
theuidviathemotorhousing.Themotormay
emerge during operation.
NOTE
Whenthemotorisnon-immersed,observeand
complywiththespecicationsfor“Max.uid
temperature”and“Non-immersedoperating
mode”.
The connection cable is longitudinally watertight
and has a bare cable end.
3.2.3. Monitoring equipment
• Motor compartment monitor:
The motor compartment monitor signals water
ingress into the motor compartment.
• Thermal motor monitor:
The thermal motor monitor protects the motor
winding from overheating. Bimetallic strips are
used for this as standard.
3.2.4. Seal
Thesealfortheuidandthemotorcompartment
is made via two mechanical shaft seals. The seal-
