The Grundfos MAGNA3 D 40-150 F (part no. 97924466) is a twin-head, cast iron, flanged circulator pump for heating, cooling and ground-source systems. It gives up to 15 m head, has a 250 mm port-to-port length and runs on a single-phase 230 V supply.

MAGNA3 adapts itself to the system with AUTOADAPT, measures flow and heat energy with built-in sensors, and connects to a BMS with an optional CIM module.

Features

AUTOADAPT control

Finds and keeps the best proportional-pressure setting for the system on its own, so the pump runs only as hard as the building needs.

FLOWADAPT and FLOWLIMIT

Set a maximum flow and the pump holds it, which can remove the need for a balancing valve on the pump circuit.

Built-in sensors

Integrated differential-pressure and temperature sensors measure the system directly, with no external sensor needed for standard control modes.

Heat energy monitor

Estimates flow and heat energy delivered, for monitoring and optimising the system (not for billing).

Grundfos GO and BMS ready

Set up and read the pump from the Grundfos GO app. Optional CIM modules connect it to common building-management fieldbus systems, and digital inputs, relay outputs and an analogue input are built in.

Permanent-magnet motor

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

Twin-head housing

Two pump heads in one housing give a built-in standby: if one head is out of service, the other keeps the system circulating.

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
Light commercial buildings and larger domestic systems

Questions about this pump

What does MAGNA3 D 40-150 F mean?

MAGNA3 is the range, 40 is the nominal pipe size (DN40) and 150 is the maximum head in decimetres (15 m). F means flanged. D means twin-head.

Can it connect to a building management system?

Yes. Fit an optional Grundfos CIM module in the control box to connect to common BMS fieldbus systems. Digital inputs, relay outputs and an analogue input are built in.

What is the difference between MAGNA1 and MAGNA3?

MAGNA3 adds AUTOADAPT, FLOWADAPT/FLOWLIMIT, built-in sensors, heat energy monitoring and fieldbus BMS communication through CIM modules. MAGNA1 has nine settings, a fault relay and a start/stop input. The equivalent MAGNA1 is the MAGNA1 D 40-150 F (99221311).

Why choose a twin-head pump?

Two pump heads share one housing, so the system keeps circulating if one head fails or is being serviced. It is common on commercial heating where loss of circulation is not acceptable.

Will it fit PN6 or PN10 flanges?

Both. The PN6/10 combination flange has bolt holes for PN6 and PN10 counter-flanges.

Will the MAGNA3 D 40-150 F fit where my old pump was?

Check the gap between your pipe flanges or unions. This pump is 250 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.
