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 100-80 F mean?

MAGNA1 is the range, 100 is the nominal pipe size (DN100) and 80 is the maximum head in decimetres (8 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 100-80 F (97924313).

Will the MAGNA1 100-80 F fit where my old pump was?

Check the gap between your pipe flanges or unions. This pump is 450 mm port-to-port. If your old pump was longer, a spacer or adaptor may be needed. 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.
