MAGNA3 32-120 F 220 1x230V PN16 wet rotor circulation pump 97924265

Circulation pump for heating and cooling systems

The Grundfos MAGNA3 32-120 F circulation pump is a high-performance device designed for circulating liquids in heating and cooling installations, both in residential and commercial buildings. The pump's design has been optimized for energy efficiency, resulting in lower operating costs. Thanks to the use of advanced technologies, such as the AutoAdapt function, the pump automatically adjusts its operating parameters to the current system needs, ensuring optimal comfort and energy savings.

The MAGNA3 pump is versatile – it is ideal for installations with radiators, fan coil units, and underfloor heating systems. Made of high-quality cast iron (GG 25), it ensures durability and reliable operation. The integrated controller allows for precise speed control, and the wide supply voltage range (230 V) simplifies installation and integration with existing infrastructure. Communication via protocols such as Modbus RTU, PROFIBUS or BACnet MS/TP enables remote monitoring and control of the pump's operation in more complex building management systems.

Key features and benefits:

• High energy efficiency (EEI 0.18): Reduces energy consumption and lowers operating costs.
• AutoAdapt technology: Automatically adjusts operating parameters to changing conditions in the installation, ensuring optimal comfort and energy savings.
• Wide range of applications: Ideal for heating, cooling and domestic hot water systems.
• Solid cast iron construction (GG 25): Guarantees durability and reliable operation even in harsh conditions.
• Integrated controller: Enables precise speed control and adaptation of the pump to specific installation needs.
• Network communication: Support for Modbus RTU, PROFIBUS, BACnet MS/TP protocols enables remote monitoring and control of the pump.
• 0-10 V / 2-10 V and 0-20 mA / 4-20 mA interface signals: Allow integration with external control systems.
• Proportional pressure or constant temperature control: Allows the pump operation to be adapted to the characteristics of the installation.
• FLOW LIMIT function: Prevents exceeding the maximum nominal flow, eliminating the need for additional throttling valves.

The MAGNA3 pump is easy to install and service. Both flanged models (PN 16) and threaded models (EN 1092-2) are available. Thanks to its compact size and the possibility of mounting in various orientations, the pump works perfectly even in limited spaces. The use of thermal insulation linings (available for single pumps) further reduces heat loss and improves the energy efficiency of the system.
