Grundfos Magna1 40-100 F circulation pump – an efficient solution for your installation

The Grundfos Magna1 40-100 F pump is an electronic circulation pump designed for use in heating, air conditioning and domestic hot water circulation systems. It is a user-friendly and energy-saving alternative to the MAGNA3 pump, ideal for both professional installers and end users. The device is distinguished by its reliability and ease of integration with building management systems.

Construction and application

The Magna1 pump is made of high-quality cast iron (GG 25), which ensures its durability and corrosion resistance. The impeller made of a different material (details in the specification) guarantees efficient operation in various conditions. It is intended for heating and cooling circuits, and can also be used in domestic hot water installations (in the stainless steel version). Thanks to its compact size (connection length 220 mm) and standard flanged connections (DN40, PN6/10), pump installation is simple and quick.

Advantages and benefits

• High energy efficiency: An energy efficiency index (EEI) of 0.2 translates to lower operating costs.
• Stepless speed control: Allows precise adjustment of the pump's performance to current system needs, further increasing energy savings.
• Built-in speed controller: Eliminates the need for additional control devices.
• Work monitoring: Continuous monitoring of the pump's status, including fault detection, allows for quick response and minimization of downtime.
• Remote control: The ability to remotely start/stop the pump using a digital input facilitates integration with building automation systems.
• Solid construction: GG 25 cast iron body ensures durability and resistance to environmental conditions.
• Wide temperature range: Operation in a temperature range from -10°C to 110°C allows the pump to be used in various installations.
• Potential-free switching contact: Allows connection to external alarm or control systems.
