INTELLIGENT SPEED-CONTROLLED PUMPS FOR HEATING SYSTEMS

GRUNDFOS MAGNA

The Grundfos MAGNA Amazingly adaptable

Intelligent circulator pumps

This brochure presents the Grundfos MAGNA circula-

tor pump range for buildings on any scale. The MAGNA

series consists of innovative, intelligent circulator

pumps designed around a permanent-magnet motor

that ensures maximum efficiency.

The intelligence of the MAGNA resides in the unique

AUTOADAPT function, which automatically sets the

pump to the most efficient performance curve at all

times. Combined with a design specifically aimed

at optimising energy efficiency, this has earned the

MAGNA series a class 'A' rating in the European

energy labelling scheme. All this makes the MAGNA

a key element in the Grundfos range of innovative

pump technology.

TheGrundfos MAGNA: Amazing variety

A full range of permanent-magnet motor circulatorsThe Grundfos MAGNA pumps are innovative, intelligent

circulator pumps designed around a permanent-magnet

motor that ensures maximum efficiency – a design pioneered

by Grundfos. With their combination of sheer strength and

unique benefits such as the AUTOADAPT function, the MAGNA

pumps have been very popular among consulting engineers,

contractors, and building owners since its introduction in

2001. Now, the range comprises 27 different sizes and models

to meet all circulation requirements.

Savings and safetyIt is easy to see why the MAGNA is so popular. It is reliable,

easy to install, and really smart. It automatically adapts its

performance to suit demand, so everyone – consultants,

installers, and end-users – can be confident that they use

the best circulator pump around. And it’s not just us saying

that: Impartial agencies also agree that the MAGNA range is

special. For example, every MAGNA model has an ‘A’ rating in

the European energy labelling scheme – a fact which clearly

demonstrates their remarkable efficiency.

For all projectsBy popular demand, Grundfos has steadily expanded the

MAGNA range to the point where it now boasts a total of 27

different models. You can enjoy the MAGNA benefits in sizes

ranging from the small 25–60 model up to the large 65–120

pump – pumps that can provide flows from as little as 1 m3/h

right up to 39 m3/h each.

You can explore the MAGNA range on the following pages. For

even more information, visit the Grundfos website or contact

us directly. We are always keen to talk MAGNA.

Threaded or fl ange connection

MAGNA pumps are available with threaded or

flange connections for easy installation into

new or existing systems.

Permanent-magnet rotor

The MAGNA pumps use a revolutionary

motor design where the rotor is based

on permanent-magnet technology,

generating greater energy savings than

any other speed-controlled circulator

pump.

Optimised hydraulics

The MAGNA pump housing and impeller are designed

to be a perfect match. Extensive 3-D testing and

simulations ensure that the hydraulics in the MAGNA

pumps are as efficient as possible – thereby reducing

energy consumption.

An inside look at the MAGNA rangeThe MAGNA pumps are the result of a development process

dedicated to creating a truly efficient circulator pump. The

design has been optimised with a view to reducing energy

consumption and making the product as smart as possible.

Nothing was left to chance: for example, sophisticated 3-D

design software and efficient flow simulation equipment

helped our engineers bring you the exceptional performance

that is the MAGNA hallmark. For the Grundfos MAGNA, only

one quality is good enough: the best.

Some of the features of the Grundfos MAGNA are briefly

described here. For more information, contact us.

In-slot winded stator

The in-slot winded stator has been specifically

developed to optimise pump efficiency.Air-cooled electronics

The sophisticated electronics behind the

MAGNA benefits are protected by air cooling,

ensuring reliable operation.

Plug-and-pump installation

Mains connection is established simply by

putting in the plug. And installation is so simple

that the MAGNA can quite accurately be called

“plug-and-pump” technology.

User-friendly interface

The MAGNA user interface is

simplicity itself. The operating

panel restricts itself to show-

ing only the most essential

performance parameters, mak-

ing it easy to read. It clearly

indicates the flow rate and the

operating level of the pump in

relation to maximum capacity.

And pump performance can

be adjusted manually with a

simple press of a button.

At start-up, a MAGNA pump operates with a lower differential pressure than other

comparable units (shown by the AUTOADAPT factory setting line).ADAPT factory setting line).ADAPT

As the flow increases, the pump pressure follows the line for the AUTOADAPT fac-ADAPT fac-ADAPT

tory setting until the pump operates on the maximum curve, continuing down-

wards until it reaches the required flow.

When the flow is subsequently reduced, the AUTOADAPT function ensures that the ADAPT function ensures that the ADAPT

operating profile does not simply return to the original curve – it sets a new, lower

pump speed (n new) that results in even greater energy savings!

Proportional-pressure control

Groundbreaking work by Grundfos led to the discovery of proportional-pressure

control. In units employing this principle, the differential pressure across the

pump is automatically adjusted to match the flow. When the flow falls, so does

the pressure required. This results in a correspondingly reduced load on the motor

– and reduced energy consumption. And things get even better when you add the

AUTOADAPT function.ADAPT function.ADAPT

Energy savings that go on and on

The Grundfos MAGNA: Amazingly adaptable

The AUTOADAPT function andwhat it does for youThe AUTOADAPT function is a unique Grundfos feature linked

to the permanent magnet motors used in the MAGNA range.

It was designed to bring real benefits to all stages of the

pump’s life: easy and accurate specification, easy installation,

efficient operation, and energy savings that go on and on.

Maximum effi ciency at all timeVery simply put, AUTOADAPT is an intelligent regulation func-

tion that keeps the MAGNA pump operating at peak efficien-

cy. It carries out regular proportional pressure adjustments

and automatically sets the pump operating profile to a more

efficient performance curve whenever possible. In effect, the

MAGNA pump learns what works best for your system – and

changes its settings accordingly.

With the MAGNA range, everybody winsIf you ever come in touch with a MAGNA pump, the AUTOADAPT

function has a benefit for you. It doesn’t matter whether you

are a pump specifier, an end-user, or an installer.

AUTOADAPT lets consulting engineers rest assured that the

MAGNA pumps meet performance specifications without

being oversized – or overpriced. They will always readjust their

setting to suit demand, ensuring minimum overall energy

consumption – but they are still ready to provide the neces-

sary flow at peak demand situations such as very cold days.

Installers benefit because in about 80% of cases, no subse-

quent manual adjustment is needed. They can quite liter-

ally install it, leave it, and forget it. And end-users need only

look at their electricity bills to see how the adaptability of

Grundfos MAGNA pumps brings substantial energy savings

year after year.

Energy labelling: an 'A' for MAGNA

Small sticker, big impact: Pump tech-

nology accounts for 20% of the world’s

annual electricity consumption, so ener-

gy-efficient products offer great scope

for savings. The energy labelling scheme

makes it easy to buy responsibly.

Energy labelling: top marks for MAGNAThe energy labelling scale, familiar from household applianc-

es since 1992, gives an easy overview of the MAGNA pumps’

annual energy consumption. The information is simple, but

make no mistake: the classifications are based on many com-

plicated calculations.

The energy efficiency is rated on a scale from A to G – A being

the most energy-efficient, G the least. The average pump

on the market today is rated D, but with the MAGNA series

Grundfos offers a complete range of circulator pumps rated A.

The difference is greater than you may think: A-rated pumps

consume up to 75% less energy than traditional standard

pumps. And of course every single MAGNA pump is rated A.

The MAGNA interface: Made for human beings

Simplicity based on careful researchAchieving simplicity can be quite a complicated process.

When designing the Grundfos MAGNA, for example, we set

up a team of software designers, industrial designers, and

anthropologists who used extensive research results to make

sure that the so-called Human-Machine-Interface was opti-

mised – in other words, that the pumps are easy to install and

operate. This attention to simplicity is evident everywhere

– for instance in the way the pumps communicate.

The control you really need. And no frills.The Grundfos MAGNA has the communication and control

features you need. No more, no less. For example, the operat-

ing panel clearly show the flow rate and the pump’s operating

level compared to its maximum capacity. And bus communi-

cation allows you to use MAGNA in any SCADA system – or

to benefit from the data collection features of GENIBus and

LONWorks.

Communication options/accessories

The R 100 remote control is a great tool for engineers and

maintenance staff. The handy unit gives easy access to

diagnostic information and general performance data.

Relay modules offer simple communication options, while

bus communication facilitates more advanced SCADA system

applications.
