Wilo Atmos GIGA-I 100/190-5.5/4 is a single-stage dry-running pump in an inline design, intended for installation in a pipeline or on a base. Thanks to its robust construction and quiet operation without vibrations, it is ideal for use in heating, cooling, and air conditioning systems with large flow rates. All components made of grey cast iron are coated with a protective KTL layer against corrosion.

The 5.5 kW motor in the IE3 class is equipped with a thermistor sensor for overheating protection and allows for star or delta start. The mechanical seal is independent of the direction of rotation and is cooled by flushing. Thanks to its high temperature and pressure resistance, the pump operates reliably even in demanding conditions with media up to 140 °C and pressure up to 16 bar.
