Submersible pump for stationary and portable wet-well installation in fully automatic mode with attached float switch.


The pumps are equipped with an open multi-vane impeller and have a free ball passage of 10 mm (TM/TMW) or 2 mm (TMR). The pressure connection is a vertical hose connection (TM) or threaded connection (TMW/TMR).


Sheath flow-cooled single-phase AC motor with integrated operating capacitor. The motor heat is transferred directly to the fluid via the motor housing.

The motor is equipped with automatic thermal motor monitoring. This means that the motor is switched off if it overheats and will be automatically switched on again once it has cooled down.


The seal is created on the fluid side by a mechanical seal, and on the motor side by a rotary shaft seal. A sealing chamber with a white-oil filling is located between the gaskets.


The pump is equipped with a 4 or 10 m long connection cable with a shockproof plug and a fitted float switch (not TM 32/8-10M).


  • Drain TMW with twister function - The twister function guarantees permanent turbulence within the pump's intake area. This prevents settling sediment from sinking and settling. This results in a clean pump sump and reduces the build-up of odours
  • Drain TMR with flat suction - The special strainer enables the fluid to be pumped out to a remaining level of 2 mm.

Delivery state

  • Pump with connection cable and plug
  • Fitted float switch (apart from TM 32/8-10)
  • Threaded connection with non-return valve (Drain TMW/TMR)
  • Hose connection, supplied (Drain TM)
  • Installation and operating instructions
