Wilo-Drain TM/TMW/TMR 32

Wilo-Drain TM/TMW/TMR 32 Advanced Submersible Pumps

The Wilo-Drain TM/TMW/TMR 32 are versatile submersible pumps designed for stationary and portable wet settings. With a built-in float switch, these pumps operate fully automatically, ensuring reliability and ease of use in everyday applications.

Type of Construction and Application

Wilo-Drain TM/TMW/TMR 32 pumps are characterized by their open, multi-channel impeller and vertical threaded connection. Their design allows efficient pumping of:

• fecal-free wastewater,
• contaminated water (with a small amount of sand and gravel).

This makes them ideal for domestic and industrial installations.

Equipment and Features

Main features of Wilo-Drain 32 pumps:

• Automatic thermal motor control - protects the operation of the motor, ensuring long life of the device.
• Integrated capacitor - allows efficient operation under varying loads.
• Built-in float switch - allows full automation of operation, responding to liquid level.

Type Designation and Versions

Example designation: Drain TMW 32/11HD-10M

• TM - the basic series of the pump,
• W - variant with "Twister" function, providing constant swirl in the suction area, preventing sedimentation,
• R - shallow suction version,
• 32 - nominal diameter of the discharge connection,
• 11 - maximum head in meters,
• HD - version adapted for aggressive media (AISI 316L materials),
• 10M - different lengths of the supply cable (10 m, 30 m or 4 m as standard).

Technical Data and Materials

Wilo-Drain 32 pumps are mains-powered (1~230 V, 50 Hz) and designed for submerged (S1) or submerged (S3 25%) operation. Protected with IP68 protection, they operate at the temperature of the pumped liquid from 3°C to 40°C. Construction includes:

• Hydraulic body: PP-GF30,
• Impeller: PPE/PS-GF20,
• Suction basket: composite material,
• Motor body: AISI 304 (for HD variants - AISI 316L),
• Seals: double sealing system (mechanical and with sealing ring),
• Power cable: with built-in plug (CEE 7/7) and float switch (on most models).

Design and Special Features

Depending on the variant, the design of Wilo-Drain pumps includes:

• Drain TM: standard submersible pump with open impeller and vertical connection,
• Drain TMW: pump with integrated swirl device (Twister function), preventing sedimentation and odor formation,
• Drain TMR: deep suction model for pumping liquids down to 2 mm level, ideal for minimizing water residue.
