Grundfos MAGNA1 F N Stainless Steel Flanged Circulator Pumps
The Grundfos MAGNA1 F N Stainless Steel Flanged Circulator Pumps range covers 24 single-head, stainless steel, flanged circulators from DN32 to DN65, with maximum heads from 4 m to 18 m. Every model runs on a single-phase 230 V supply and carries a 2-year Grundfos warranty.
MAGNA1 offers nine settings across proportional pressure, constant pressure and constant curve, a fault relay and start/stop input for BMS connection, and the same efficient permanent-magnet motor as MAGNA3. Every model in this range has a stainless steel pump housing.

How to choose
- Match the pipe size and the port-to-port length of the pump you are replacing.
- Pick a maximum head above your system's needed head; the pump's control will turn it down to suit.
- Cast iron or stainless steel (N) housing, to suit the system.
- Twin-head (D) where the building cannot lose circulation if one pump head fails.
- MAGNA3 for AUTOADAPT, heat energy monitoring or fieldbus BMS communication; MAGNA1 for nine-setting control with a fault relay and start/stop input.
