MAGNA3 65-80 F 340 1x230V PN16 wet rotor circulation pump 97924302

Flueless circulation pump for efficient heating and cooling. The MAGNA3 65-80 F circulation pump is an advanced solution designed for circulating water in heating and cooling systems. Its design, based on a flueless technology, minimizes the risk of the pump becoming blocked by impurities, which translates into reliability and long service life. This device is characterized by high energy efficiency (EEI 0.18) and the ability to precisely adjust, adapting its operating parameters to the current needs of the installation.

The MAGNA3 pump is equipped with an integrated controller that allows it to operate in various modes – proportional pressure, constant pressure, constant temperature and constant flow (available from production code 1838). This allows it to be optimally adapted to the specifics of a particular system, achieving significant energy savings and user comfort. In addition, the pump offers wide communication possibilities – it supports PROFIBUS, RS-485, EtherNet/IP, Modbus RTU, BACnet MS/TP and LON/LONWorks protocols – which facilitates integration with building automation systems.

Design and application

The MAGNA3 pump has been designed with ease of installation and maintenance in mind. Made of high-quality cast iron (GG 25), it provides durability and corrosion resistance. Flanged connections (EN 1092-2) facilitate connection to the installation. The device is designed to operate at temperatures from -10°C to 110°C and at a maximum working pressure of 16 bar. Thanks to its parameters, it is ideally suited for both heating installations with heat exchangers and air conditioning installations with fan coil units or cooling surfaces. It is worth noting that twin-head pumps have check valves to prevent liquid backflow between the heads, which affects their independent operating characteristics.

Advantages and benefits

• High energy efficiency: An EEI of 0.18 means significant energy savings compared to older pump models.
• Versatility: The ability to operate in various control modes allows the pump to be adapted to a variety of heating and cooling systems.
• Communication: Support for many communication protocols facilitates integration with BMS (Building Management System) systems.
• Reliability: The flueless design minimizes the risk of failure caused by impurities.
• Simple operation: The integrated controller and intuitive interface make configuration and pump monitoring easy.
• Wide range of applications: Ideal for both heating and air conditioning installations.
• FLOW LIMIT function: Prevents exceeding the nominal flow, eliminating the need for additional throttling valves (available in selected models).
• Remote control option: Thanks to radio communication (option), the pump can be controlled using the Grundfos GO application or other MAGNA3 pumps of the same type.

The MAGNA3 pump is an investment in comfort, energy savings and the reliability of the heating or cooling system – both for professional installers looking for an efficient solution for their clients, and for end users who value convenience and low operating costs.
