Achieving maximum power with peak energy efficiency.
For buildings requiring high delivery heads and large volume flows, the Wilo-Stratos GIGA is the ideal high-efficiency pump for heating, air-conditioning, and cooling systems.
Features/Product Advantages
Innovative high-efficiency pump delivering maximum overall efficiency
High-efficiency motor with IE5 energy efficiency rating, compliant with IEC 60034-30-2 standards
Optional interface available for building automation connectivity via plug-in IF modules
Construction
High-efficiency glanded in-line pump featuring an IE5 motor and electronic power control. Single-stage, low-pressure centrifugal pump with flanged connections and mechanical seal.
Applications
Pumping of heating water (in accordance with VDI 2035), cold water, and water-glycol mixtures in heating, chilled water, and cooling systems; the fluid must be free of abrasive substances.

Technical Data
Permissible fluid temperature range: -20 °C to +140 °C
The mechanical seal is suitable for pumping water at temperatures up to Tmax = +140 °C. At temperatures of T ≤ +40 °C, pumping water-glycol mixtures with a glycol volume content of 20% to 40% is permitted. A different mechanical seal is required if the glycol volume content in the water-glycol mixture exceeds 40% (up to a maximum of 50%), if the medium temperature exceeds +40 °C (up to a maximum of +120 °C), or if media other than water are used. When using water-glycol mixtures, the S1 model equipped with the appropriate mechanical seal is generally recommended. Power supply:
3~440 V ±10%, 50/60 Hz
3~400 V ±10%, 50/60 Hz
3~380 V -5% +10%, 50/60 Hz
EMC compliance without additional measures:
Interference emission for residential areas: EN 61800-3:2018
Interference immunity for industrial areas: EN 61800-3:2018
Protection class: IP55
Nominal diameters: DN 40 to DN 200
Max. operating pressure: 16 bar at up to +120 °C; 13 bar at up to +140 °C
