Circulation pump for demanding installations

The Grundfos MAGNA1 D 50-60 F 240 is an electronic circulation pump designed for efficient operation in heating, air conditioning systems, and domestic hot water circulation. It is a simple yet advanced solution that combines high energy efficiency with intuitive control. It is an economical alternative to the MAGNA3 pump, while offering reliability and functionality.

Design and application

The MAGNA1 D pump features a solid construction with a cast iron (GG 25) housing, ensuring durability and corrosion resistance. The impeller made of a material other than stainless steel (details in the technical documentation) guarantees optimal hydraulic performance. Thanks to the ability to operate in dual pump mode, it ensures continuous system operation – in the event of a failure of one pump, the other automatically takes over its task, minimizing downtime. This is particularly important in critical applications where reliability is a priority.

The pump is perfect for:

• Heating of commercial and residential buildings
• Air conditioning systems
• Domestic hot water recirculation
• Mixing loops
• Geothermal heat pump systems
• Small refrigeration applications

Advantages and benefits

• High energy efficiency: Meets the requirements of the EuP 2015 directive, which translates into significant energy savings. The energy efficiency index (EEI) is 0.23.
• Simple operation: An intuitive user interface makes configuration and pump monitoring easy.
• Maintenance-free design: Thanks to the fixed impeller, the pump does not require regular maintenance.
• Dual pump function: Provides redundancy and continuous system operation in the event of a pump failure. Automatic switching between pumps guarantees uninterrupted flow.
• Remote control: A digital start/stop input allows for remote starting and stopping of the pump.
• Operating monitoring: A built-in fault relay informs about any problems with pump operation.
• Wide range of applications: The pump can be used in various heating, cooling and domestic hot water circulation systems.
• Solid construction: The cast iron housing ensures durability and corrosion resistance.
• Maximum working pressure: 10 bar - ensures the safety of the installation.

The MAGNA1 D 50-60 F 240 pump is an investment in a reliable and energy-saving solution for your heating or air conditioning system. Its versatility and ease of use make it an ideal choice for both professional installers and end users.
