Why Choose the Grundfos MAGNA1?

tick

Lower Running Costs

Variable speed operation allows the pump to adjust its output to changing system demand, helping to minimise unnecessary energy use and reduce ongoing operating costs.

tick

Flexible Pump Control

With proportional pressure, constant pressure and constant speed settings, the MAGNA1 can be configured to suit different system requirements.

tick

Single or Twin Head

The range is available in both single- and twin-head configurations, giving greater flexibility when specifying circulation pumps for different system designs.

tick

Wide Application Range

From commercial heating and cooling to domestic water, ground-source heat pumps and solar systems, MAGNA1 pumps can be used across a broad range of applications.

tick

High System Pressure

With a maximum system pressure of 16 bar, the MAGNA1 is suitable for demanding commercial circulation applications where higher pressure capability is required.

tick

Temperature Flexibility

The MAGNA1 can handle liquid temperatures from -10 °C to +110 °C, making it suitable for both heating and cooling applications across a wide range of system conditions.
