Wilo-Atmos GIGA-NF

The norm pump for automatic firefighting applications.

Wilo-Atmos GIGA-NF-E (VdS)

The norm pump for automatic firefighting applications.

The Wilo-Atmos GIGA-NF norm pump offers high reliability and long service life as an entry level model for automatic firefighting thanks to its corrosion-resistant components. The user-friendly “back pull-out” design also simplifies maintenance. The Wilo-Atmos GIGA-NF offers high operational reliability. It is VDS tested and protected against overheating in case of application. Their modular design also allows them to be equipped with both diesel and electric motors. The diesel version has a large reservoir that allows firefighting for up to six hours. The pump is mounted on a base frame, making it very easy and safe to transport, install and maintain.

Your advantages

High reliability and durability thanks to cataphoretic coating of all cast components, bronze impeller and stainless steel slip rings for high corrosion resistance
User-friendly “back pull-out” design for easy maintenance
Different drives depending on individual requirements
Valve at pump outlet ensures minimum water flow to protect against overheating
Easy and safe transport, installation and maintenance thanks to solid construction on base frame
