MAGNA1 40-80 F Circulator Pump

The MAGNA1 40-80 F from Grundfos is a high-performance wet rotor circulator pump, specifically designed for heating, air conditioning, and district heating applications in commercial buildings. Its robust design and simplified electronics make it an efficient, quiet, and easy-to-install solution, ideal for replacing old circulators or for projects with basic control needs.

This pump complies with the EuP 2015 standard, ensuring reduced energy consumption thanks to its energy efficiency index (EEI) below 0.23. Its permanent magnet rotor technology and optimized electronics ensure reliable operation, with low noise levels and minimal consumption. It features electronic control with three main modes: proportional pressure, constant pressure, and constant curve, with various adjustment levels according to the hydraulic system.

The MAGNA1 is equipped with a digital input for start/stop and configurable status and alarm relays in NO or NC contacts, facilitating its integration into basic management or supervision systems. Additionally, it incorporates the Grundfos Eye system, providing visual information on the pump's operational status through integrated LED indicators.
