Circulation pump for heating and domestic hot water systems

The Magna1 pump is an electronic circulation pump designed for use in heating, air conditioning and domestic hot water circulation systems. It is an economical alternative to the MAGNA3 pump, while offering high energy efficiency and easy integration with building management systems. It is a versatile solution, suitable for both domestic and commercial installations.

Construction and application

The Magna1 pump is characterized by a solid construction with a housing made of cast iron GG 20 (GJL-200), which ensures durability and corrosion resistance. The impeller made of PES 30%GF material guarantees reliable operation in various working conditions. The intended use of the pump includes:

• Heating installations – both in single-family homes and commercial buildings.
• Air conditioning and cooling installations.
• Circulation of domestic hot water in commercial buildings and single-family homes.
• District heating and cooling networks.
• Industrial heating.

Thanks to the wide range of operating temperatures (-10°C to 110°C) and maximum operating pressure of 10 bar, the pump is suitable for various applications.

Advantages and benefits

The Magna1 pump offers a number of benefits for both installers and end users:

• Simple installation: An intuitive user interface makes it easy to start up and configure the pump, especially when replacing older models.
• Low energy consumption: The energy efficiency index (EEI) of 0.2 provides energy savings and reduced operating costs.
• Built-in speed controller: Allows stepless speed adjustment, adapting the pump's performance to the current needs of the system.
• Dual pump function (in some models): Ensures continuous system operation by automatically switching to the second pump in the event of a failure of the first.
• Grundfos Eye optical indicator: Facilitates monitoring of the pump status and quick identification of potential problems.
• Safety: Has a built-in pump switch and a fault interface signal, which increases safety of use.
• Durability: Made of high-quality materials, guarantees a long service life without the need for maintenance.
• Versatility: nine control modes allow you to adapt the pump's operation to the specifics of the installation.

The pump is equipped with a potential-free switching contact, which enables integration with external monitoring and building control systems. The connection length is 180 mm and the connection diameter is 1 1/2 inch (40). The motor power consumption (P1) is 0.188 kW with a rated current of 1.51 A and a voltage of 230 V/50Hz or 60Hz. The degree of protection IPX4 provides protection against splashing water.
