Features

Nine simple settings

Three control modes, proportional pressure (PP1–PP3), constant pressure (CP1–CP3) and constant curve (I–III), chosen at the push of a button.

Permanent-magnet motor

High-efficiency PM motor with integrated frequency converter. No external motor protection needed and no routine maintenance.

BMS relay and start/stop input

Potential-free fault relay (opens on a fault) and a digital input for external start/stop, so the pump links to a building management system or PLC.

Grundfos GO app

Set up and read the pump from the Grundfos GO app: infrared on single-head pumps, radio on twin-head pumps.

Straightforward replacement

Designed to replace Grundfos UPS and older MAGNA circulators in refurbishment work.

Low noise, long life

Wet-rotor (canned) design with no shaft seal to leak or wear. Quiet running in occupied buildings.

Applications

Wet heating systems: radiators, underfloor heating and air-handling coils
Chilled water and air-conditioning circuits (liquid down to -10 °C)
Ground-source heat pump and solar heating circuits
Commercial buildings, schools, hospitals and district heating sub-stations

Questions about this pump

What does MAGNA1 80-40 F mean?

MAGNA1 is the range, 80 is the nominal pipe size (DN80) and 40 is the maximum head in decimetres (4 m). F means flanged.

Can it connect to a building management system?

Yes. It has a potential-free fault relay and a digital input for external start/stop, so it links to a BMS or PLC. For full fieldbus communication, choose MAGNA3 with a CIM module.

What is the difference between MAGNA1 and MAGNA3?

MAGNA1 has nine settings, a fault relay and a start/stop input for BMS connection. MAGNA3 adds AUTOADAPT, FLOWADAPT/FLOWLIMIT, built-in sensors, heat energy monitoring and fieldbus BMS communication through CIM modules. The equivalent MAGNA3 is the MAGNA3 80-40 F (97924306).

Will it fit where my old pump was?

Check the gap between your pipe flanges. Send us the old pump’s nameplate and we will confirm the right replacement.

What warranty does it have?

A 2-year Grundfos manufacturer warranty.
