The Grundfos MAGNA1 32-80 is a compact, energy efficient circulating pump built for domestic and light commercial heating systems. Designed as a direct, no-fuss replacement for older fixed speed circulators, it pairs a permanent magnet synchronous motor with a maintenance free canned rotor design to keep hot water moving quietly and reliably around your system.
With an Energy Efficiency Index (EEI) of 0.20, this pump can significantly cut electricity consumption compared with older, single speed circulators - helping home owners lower running costs and helping installers meet current energy efficiency expectations on every job. The standard 180 mm port to port length and 2″ (G2) threaded connections mean it fits straight into the space left by most legacy circulators, with minimal re-piping required.
Whether you are upgrading a domestic boiler system, servicing a mixing circuit, or specifying a reliable circulator for underfloor heating and air conditioning surfaces, the MAGNA1 32-80 delivers dependable performance with virtually no maintenance and an intuitive, easy to set interface.
