A reliable, robust, and durable standard pump for industrial applications.

The Wilo-Atmos GIGA-NX is available in various models featuring different motor and material options, with an operating temperature range of -20 to +140°C. These features make this dry-rotor pump a configurable, versatile solution suitable for a wide range of industrial applications.

Designed for continuous operation, the pump features corrosion-resistant stainless steel hydraulics and maintenance-free ball bearings to ensure a long service life. A spacer coupling facilitates quick mechanical seal replacement during maintenance. The Wilo-Atmos GIGA-NX supports speed control via the Wilo-EFC frequency converter and can be equipped with temperature and vibration monitoring systems for the early detection of potential faults.

Wilo also offers the "WiloCare" after-sales service package, covering the entire product lifecycle from commissioning to maintenance. Wilo's remote monitoring system ensures reliable operation and peace of mind.

Commissioning

When pumps operating at 2900 rpm are installed in residential buildings, appropriate noise insulation and noise reduction measures must be implemented.
Pump performance curves and specific motor power requirements depend on the fluid being pumped. Variations in the concentration and/or viscosity of the pumped fluid significantly affect pump performance curves and motor power requirements. Please refer to the "Recommended configuration limits" table! Recommended configuration limits are calculated as follows: Qoptimum (flow rate at peak pump efficiency) derived from the specific pump performance curve; and Qmin and Qmax coefficients derived from the "Recommended configuration limits" table. Qmin configuration = Qmin x Qoptimum; Qmax configuration = Qmax x Qoptimum. Example: Model Atmos GIGA-NX 032-125: Qmin = 0.3 x 8 = 2.4 m³/h; Qmax = 1.2 x 8 = 9.6 m³/h.
Load-dependent pump power: All standard Wilo pumps are equipped with IEC standard motors. Wilo controllers are suitable for automatic, load-dependent speed control of pumps driven by standard motors.
