Hydraulics

The pumps of the TM series are equipped with a multi-channel impeller and have a free ball passage of 10 mm (except TMR). The pressure connection is a vertical threaded connection.

Configuration options:

  • TMW
    The Wilo-Drain TMW’s twister function ensures continuous turbulence in the suction area of the pump, preventing the sinking and settling of settling sediments. This results in a clean pump sump and reduces the build-up of odours. The Twister function can be disabled.
  • TMR
    The Wilo-Drain TMR’s special strainer enables pumping off of the fluid to a residual level of 2 mm.

Motor

Submersible motor in single-phase version with sheath current cooling (cooling by the pumped fluid between pump and motor housing) and built-in thermal overload protection with automatic reactivation.

Seal

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

Cable

The pump is equipped with a 3 or 10 m connection cable with shockproof plug and an attached float switch (not TM 32/8-10M).


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.
