Wilo-Atmos GIGA-NX
The reliable and robust standard pump for industrial applications.
The reliable and robust standard pump for industrial applications.
With its range of versions, the Wilo-Atmos GIGA-NX offers a wide variety of motors and materials and can be operated in a temperature range from -20 to +140 °C. This makes the glanded pump a configurable all-round solution for diverse industrial applications.
Designed for continuous operation, the pump features corrosion-resistant stainless steel hydraulics and a maintenance-free ball bearing ensuring a long service life. The spacer coupling enables quick replacement of the mechanical seal for maintenance purposes. The Wilo-Atmos GIGA-NX enables speed control with a Wilo-EFC frequency converter and can be equipped with temperature and vibration monitoring for early detection of impending downtime.
In this context, Wilo offers additional services which range from commissioning to maintenance. With the all-inclusive, worry-free WiloCare package, Wilo remote monitoring ensures optimal operational reliability.
