Wet rotor circulation pump MAGNA3 32-40 180 1x230V PN10 97924254

MAGNA3 Circulation Pump – an efficient solution for your installation

The Grundfos MAGNA3 32-40 180 circulation pump is an advanced device designed for circulating water in central heating, air conditioning and domestic hot water systems. The wet-rotor, glandless design ensures quiet operation and minimizes the risk of failure. It is a solid choice for both professional installers and demanding users.

Functionality and versatility

MAGNA3 is a pump that adapts to the needs of the installation. The built-in controller with a TFT panel allows precise setting of operating parameters, and optional CIM modules expand its functionality. Thanks to the use of a differential pressure and temperature transducer, the pump optimizes efficiency, reducing energy consumption. Compatibility with various communication protocols (RS-485, EtherNet/IP, Modbus RTU, BACnet MS/TP, LON/LONWorks) allows for easy integration with intelligent building systems.

Construction and materials

The pump housing made of gray cast iron (GG 20) guarantees durability and corrosion resistance. The rotor sleeve made of carbon fiber reinforced composite and the bearing shield made of stainless steel ensure reliable operation in harsh conditions. Air-cooled electronics increase the lifespan of the device. The pump is designed to operate at an ambient temperature of 0 to 40°C and medium from -10…110°C. The maximum working pressure is 10 bar. Threaded BSPP connections with a diameter of 2 inches (50 mm) facilitate installation in existing systems.

• The pump capacity reaches a maximum of 4.15 m³/h with a head of up to 4 meters, ensuring efficient circulation in the system.
• High energy efficiency – an energy efficiency index (EEI) of 0.18 translates to lower operating costs.
• Stepless speed control allows precise adjustment of the pump operation to the current needs of the heating or cooling system.
• Insulation class F and protection degree IPX4 guarantee safety of use and resistance to external factors.
• A wide range of communication protocols (PROFIBUS, RS-232, RS-485, BACnet, Modbus) facilitates integration with building automation systems and remote pump control.
• Availability of 0-10 V / 2-10 V and 0-20 mA / 4-20 mA interface signals allows integration with external control and process monitoring systems.
