Energy savings due to increased overall efficiency through improved hydraulics and IE3 motors
Cataphoresis coating of all cast iron parts for high corrosion resistance and durability
Versatility of use thanks to standard sizes, different motor variants and impellers in different materials
Easy maintenance thanks to interchangeable Back-Pull-Out coupling
High operational reliability due to improved impeller design providing pressure relief
Standard pump for universal use and a long service life.
The Wilo-Atmos GIGA-N is the entry-level model for dry-running pumps. A large variety of motors and materials as well as a wide temperature range from -20 °C to +140 °C make it universally suitable for many applications.

The pump designed for long-term operation ensures a long service life thanks to its corrosion-resistant coating and maintenance-free ball bearing. During maintenance, a replaceable sleeve allows the mechanical seal to be replaced as quickly as possible. The speed of the Wilo-Atmos GIGA-N can be adjusted with the Wilo-EFC converter. A temperature and vibration monitoring system for the pump bearings can be installed to detect possible failures at an early stage.

Wilo offers extensive, customer-specific services from start-up to service and with the WiloCare universal and comprehensive monitoring package, Wilo remote monitoring ensures optimum operational reliability.
