Design
Basement drainage water pump, water-cooled
Application in Water
- For pumping water clear or slightly muddy water
- From water tanks, sumps or pits
- For water overflows and flooding
- For draining water basement stairways and basement areas
The TMR is suited for lowering the water level to a remaining water level of 2 mm.
The service life of submersible pumps water, which are used in water pump sumps and through which washing machine water, soapy water from basins and showers, or other mixtures water flow, is considerably reduced by settling sediment. Such sediment can form deposits in the water pump sump, resulting in the accumulation of mud and odours.
Wilo-Drain water TMW 32 has a turbulator that prevents the build-up of sediment, expelling it together with the fluid in water. This reduces costs and the time needed for regular cleaning water of the sump. In addition, problems associated with mud removal and the observance of occupational safety hygiene regulations during cleaning water of the pump sump are minimized.

Description/design
Submersible pump water suitable for stationary, fully automatic operation. A pressure hose of appropriate length is connected for mobile use, while a pipe is connected to the pressure port for stationary applications. A residual current device for a trigger current of 30 mA that is to be provided onsite (regulation concerning outdoor installation) must be utilised in accordance with EN 60335-2,41.
The pumps of the TM series are suitable for drainage applications with a multi-channel impeller and a free ball passage of 10 mm according to EN 12050-2 (except TMR).
The water pump is continuously cooled by the fluid between the outside shroud of the water pump and the stainless steel motor housing. The serially installed thermal motor protection assures a permanent protection of the pump. The pump is equipped with a 3 or 10 m connecting cable with shockproof plug and a float switch (not TM 32/8-10M).
TMR
The Wilo-Drain TMR water pumps are built for special applications whereby it is essential to keep the amount of residual water low. The special strainer enables the fluid to be pumped out to a remaining level of 2 mm.
TMW
Due to its design, the Wilo-Drain TMW ensures constant turbulence in the suction area of the pump. This results in a clean pump sump.
No fluid-related odours are generated, due to the turbulence and the elimination of the settling sediment connected with it. The maintenance intervals are extended.
Deactivating the Twister (see installation and operating instructions) increases the pump curve by 1 m.
Motor
Jacket-cooled, stainless steel-encapsulated, dry electric motor with built-in thermal overload protection and automatic reactivation.
Cable
In accordance with DIN EN 60335-2-41, 10 m of electrical connection line should be used for outdoor operation (however note that regulations vary from country to country).
Sealing of water pumps/motor compartment
Mechanical seal on impeller side, one rotary shaft seal on motor side; there is an oil chamber between the seals.
Scope of delivery
Pump ready for connection with cable, plug and attached float switch (except for TM 32/8), supplied non-return valve (except for TM 32/7), installation and operating instructions.
