Wilo-Atmos GIGA-B - 60Hz

The reliable all-rounder for heating, air-conditioning and cooling applications in large buildings.

Your advantages
Wilo-Atmos GIGA B

The reliable all-rounder for heating, air-conditioning and cooling applications in large buildings.

The Wilo-Atmos GIGA-B is a glanded pump in monobloc design, which is particularly suitable for transporting water in a variety of building types. The pump is characterised by its low life cycle cost thanks to its optimised hydraulic efficiency and ensures a long service life due to the corrosion-resistant cataphoretic coating of all cast components. A great variety of components as well as its wide temperature range from -20 °C to +140 °C makes it an all-rounder with a broad coverage of applications.

Installation and maintenance are customer-friendly thanks to standard pump support feet, back pull-out design with optional cartridge mechanical seal for large pump types (from 37 kW/4-pole). Due to its main dimensions in accordance with EN 733 it is compatible with many existing monobloc pumps. With the launch of the Atmos GIGA-B, Wilo has another glanded pump series at the cutting edge of technology under its belt.


Your advantages

  • Energy-saving due to state-of-the-art pump hydraulics and usage of IE3 motors
  • Universal use in diverse applications thanks to different impeller materials, several motor options as well as different mechanical seals
  • Easy installation due to standard pump support feet and optional supporting block
  • Easy maintenance and user-friendly design with optional back pull-out design and cartridge mechanical seal for large pump types
  • Cataphoretic coating of all cast iron components ensures high resistance to corrosion and long service life
  • Meets user requirements due to performance and main dimensions in accordance with EN 733 (DIN for end-suction pumps)

Environmentally friendly features

  • Efficient pump hydraulics and usage of IE3/IE4 motors for high energy saving
  • Efficient design of cast iron components for lowest possible weight
  • Sustainable and carbon-neutral production and processes in our European factories

Technical data

  • Permissible temperature range of -20 °C to +140 °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.
