Stratos GIGA is a glanded, high-efficiency in-line pump with an EC motor and electronic duty adaptation.

It is used for the pumping of heating water (acc. to VDI 2035), cold water and water / glycol mixtures without abrasive substances in heating, cold water and cooling systems.

The GIGA version is a single-stage low-pressure centrifugal pump with flange connection and mechanical shaft seal.

Design
