Grundfos MAGNA3 D 100-40 F

For any serious commercial system, a powerful and reliable circulator pump is the top priority. A solution must meet the highest performance demands while providing total peace of mind. At National Pumps and Boilers, we recommend the Grundfos MAGNA3 D 100-40 F, an intelligent twin-head pump engineered to deliver exceptional performance and eliminate system downtime.

The Smart Solution for Unmatched Performance and Reliability

A pump failure on a large-scale heating or cooling system is a crisis, leading to shutdowns and costly repairs. The Grundfos MAGNA3 D is your system's insurance policy, engineered for robust performance and absolute reliability. Its genius lies in the twin-head design, providing double the performance and drastically reducing downtime through three intelligent, seamless multipump modes.

In Backup Mode, the pump automatically switches to the second head if the primary one fails, effectively eliminating downtime and ensuring continuous service. For long-term efficiency, Alternating Operation balances the workload between heads, ensuring even wear to extend the pump's service life. During peak demand, Cascade Mode activates both heads for maximum performance, guaranteeing your heating or cooling needs are always met. The pumps communicate wirelessly, making the entire system easy to manage.

Beyond its failsafe design, this pump is incredibly smart. It features Grundfos’s renowned AUTOADAPT technology, which constantly analyses your system’s needs. It learns and predicts, adjusting its output to slash energy costs by up to 75% compared to conventional pumps. This provides total system control without constant manual adjustments. The wireless communication also allows for a simplified installation, making it one of the most efficient and dependable commercial circulators on the market.

The Perfect Fit for High-Performance Applications

The MAGNA3 D is the ideal choice for a wide range of high-performance applications. Its versatility and power make it perfectly suited for:

• Commercial heating & air conditioning
• Domestic heating & hot water recirculation
• District heating & cooling
• Industrial heating

It is the ideal core for any demanding commercial boiler or large-scale cooling network, providing the power and intelligence needed to keep things running smoothly.
