Description/Design

Submersible pump for stationary and mobile submersible installation for fully automatic operation thanks to integrated float switch.

Hydraulic part

The TM series pumps are equipped with an open multi-vane impeller and have a free passage of 10 mm according to (excluding TMR). The pressure connection is made as a vertical screw connection.

Versions

• TMW
  The Wilo-Drain TMW, thanks to the Twister function, continuously creates a turbulence in the suction area of the pump, thereby preventing sinking and sedimentation. This eliminates contamination of the bottom of the shaft and reduces the risk of unpleasant odors. The Twister function can be deactivated.
• TMR
  The Wilo-Drain TMR, thanks to a special suction filter, ensures that liquids are pumped down to a residual level of 2 mm.

Electric motor

Submersible motor in single-phase version with a cooling jacket (cooling is provided by the pumped liquid flowing between the pump housing and the motor housing) and built-in thermal overload protection with automatic restart function.

Seal

On the side of the pumped liquid - a mechanical seal, on the side of the electric motor - a shaft seal ring. Between the seals is a seal chamber filled with white oil.

Cable

The pump is equipped with a 3 and 10 m power cable with a shock-proof plug and a float switch (not TM 32/8-10M).
