Atmos GIGA-I
In-line pump
The universal glanded pump for heating, air-conditioning and cooling applications in large buildings.
- Universal use in different applications, with different fluids and temperatures thanks to diverse components such as impellers, motor sizes and mechanical seals
- State-of-the-art pump hydraulics and IE3/IE4 motor technology for reliable and energy saving operation
- Long service life thanks to corrosion-resistant cataphoretic coating of all cast components
- Targeted discharge of condensate when used in air-conditioning systems and chillers
- Easy installation with the possibility of securing the pump feet for maximum stability
- Easy maintenance and user-friendly design with optional back pull-out design and cartridge mechanical seal for large pumps
- Available with ATEX approval for use in industrial environments

Technical data
- 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.
