Wilo-Atmos GIGA-I Industrial Heating Circulating Water Pump

Glanded pump in in-line design with flange connection

The pumping of heating water (in accordance with VDI 2035), chilled water and water-glycol mixtures without abrasive substances in heating, chilled water and cooling systems.

• Permitted temperature range of the fluid: -20 °C to +140 °C
• Max. ambient temperature 40 °C
• Mechanical seal for pumping water up to Tmax = +140 °C. Up to T ≤ +40 °C, a glycol admixture of 20 % to 40 % by volume is permissible. An alternative mechanical seal must be provided for water-glycol mixtures with a glycol content of > 40% to max. 50% by volume and a fluid temperature of > +40 °C to max. +120 °C or other fluids that differ from water. When using water-glycol mixtures, the use of an S1 variant with a corresponding mechanical seal is generally recommended.
