Wilo-Yonos GIGA-N

Series description

Your advantages

  • Efficient pump thanks to the use of IE4 motors
  • Cataphoretic coating of all cast components for high resistance to corrosion and long service life
  • Standard dimensions in accordance with EN 733 make the pump universally deployable
  • Easy adjustment and operation with Green Button Technology
  • Easy maintenance thanks to user-friendly spacer coupling in back pull-out design
  • Optional interfaces for connection to building automation using insertable IF modules

The standard pump for universal applications and high energy efficiency.

The Wilo-Yonos GIGA-N is a pump with high energy efficiency for use in heating, air conditioning and cooling applications in buildings with high delivery heads that require the movement of large volumes of water.


Electronically controlled, single-stage low-pressure centrifugal pump with axial suction. Mounted on a baseplate with flange connection and automatic power adjustment.


  • The pumping of heating water (in accordance with VDI 2035), cold water and water-glycol mixtures without abrasive substances in heating, cold water and cooling systems.
  • Applications for irrigation, building services, general industry, power stations, etc.
