Wilo-Medana CH3-LE

Efficient, functional and reliable horizontal multistage pump

Your advantages
Wilo-Medana CH3-LE

Efficient, functional and reliable horizontal multistage pump

The Wilo-Medana CH3-LE is the next generation of horizontal, multistage pumps equipped with a highly efficient IE5 EC motor, a new inverter and the proven Medana CH1 hydraulics. 

It has comprehensive functionality thanks to integrated control modes and various functions such as dual pump management and dry-running detection.

With the CIF module, remote access and connection to networks and systems is possible. Thanks to the intuitive menu navigation on the 2" LCD colour display and plain text, it is also easy to operate.

The compact and robust design allows both drinking water applications and use at ambient temperatures from -15 °C to +50 °C. In this way, it offers a very wide range of applications for the commercial sector.


Your advantages

  • Reduced energy consumption due to highly efficient IE5 EC motor, new generation inverter and proven hydraulics
  • Integrated control modes (dp-v, dp-c, p-c, n-cont, PID) and various functions such as dual pump management and dry-running detection
  • Easy installation and commissioning thanks to 2" LCD colour display, operating keys and plain text
  • High transparency during pump operation due to visibility and setting of parameters in all control modes and functions
  • Remote access and connectivity through CIF module 
  • Robust pump design due to stainless steel pump material
  • Wider range of applications due to ambient temperatures from -15 °C to +50 °C
