Wet rotor circulation pump MAGNA3 25-40 180 1x230V PN10 97924244

Circulation pump for efficient heating and cooling

The Grundfos MAGNA3 25-40 circulation pump is an advanced solution designed to force fluid circulation in central heating, air conditioning, domestic hot water and solar systems. The pump's construction, with a housing made of durable cast iron, guarantees reliability and long life even in harsh working conditions. This model is characterized by high energy efficiency (EEI 0.18), which translates into lower operating costs.

The MAGNA3 pump offers a wide range of configuration and control options, thanks to support for communication protocols such as Modbus RTU, PROFIBUS, BACnet MS/TP, LON/LONWorks and EtherNet/IP. The built-in motor speed controller allows for smooth speed adjustment, adapting the pump's performance to the current system needs. 0-10 V / 2-10 V and 0-20 mA / 4-20 mA interface signals allow integration with external control systems.

Application and functionality

The MAGNA3 pump is ideal for both new and modernized installations. Its compact design (connection length 180 mm) makes it easy to install even in limited spaces. Cylindrical gas threads (BSPP) with a diameter of 1 1/2 inches provide a tight and durable connection to the installation. The ability to operate in a temperature range from -10 to +110°C makes the pump universal and can be used in various heating and cooling applications.

• Versatility: Suitable for central heating, air conditioning, domestic hot water and solar systems.
• Efficiency: Low EEI index (0.18) ensures energy savings.
• Communication: Support for many communication protocols facilitates integration with BMS (Building Management System) systems.
• Regulation: Smooth speed control allows for optimization of pump operation and adaptation to current system needs.
• Durability: The housing made of cast iron GG 20 (GJL-200) provides corrosion resistance and long life.
• Safety: Insulation class F and protection class IPX4 guarantee safe operation in various environmental conditions.
• Flexibility: The ability to connect analog signals (0-10V/2-10V, 0-20mA/4-20mA) increases the possibilities of controlling the pump.
• Performance: Maximum head 4 m at a nominal flow rate of 3.71 m³/h ensures adequate circulation of the medium in the installation.

The MAGNA3 pump is an investment in comfort and savings – a reliable solution for demanding installers and end users looking for an efficient and durable circulation pump.
