Wilo Stratos GIGA2.0-D, 125/1-17/7,5, Circulation Pump

Description

Highly efficient inline pump with EC motor in energy efficiency class IE5 according to IEC 60034-30-2, lowest hydraulic efficiency index MEI ≥ 0.7 and electronic capacity adjustment in construction with dry motor. The pump is of the single-stage centrifugal pump type with flange connection and mechanical shaft seal. Stratos GIGA2.0-D is primarily intended for pumping heating water (according to VDI 2035), cold water and water-glycol mixtures without abrasive particles in the heating, climate and cooling systems.
