Submersible pump for stationary and portable wet well installation for fully automatic operation, thanks to float switch installation.

Hydraulic section

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

Electric motor

Single-phase motor with cooling jacket and built-in operation condenser. The motor heat is dissipated directly by the fluid being pumped through the motor housing.

The electric motor is equipped with an automatic motor winding temperature sensor. This means that the motor stops on overheating and restarts automatically after cooling down.


On the fluid side there is a mechanical seal, on the motor side a rotary shaft seal. Between the seals there is a sealing chamber filled with white oil.


The pump is equipped with a 4 or 10 m power cable with plug and socket and an integrated float switch (except TM 32/8-10M).


Drain TMW with vortex function - the vortex function provides continuous vortex creation in the suction area of the pump. This prevents sediment from sinking and settling. This prevents contamination of the sump bottom and reduces the risk of odors
Drain TMR with dewatering to the lowest level - A special suction filter allows pumped liquid to be dewatered to a minimum level of 2 mm.
