MAGNA3

Reliable innovation

The MAGNA3 is a circulator pump based on the tried and tested MAGNA technology and our

industry-leading experience with electronic pumps. The permanent magnet motor, AUTOadapt

function and integrated frequency converter is still part of the MAGNA package, but we’ve

added some additional, ground-breaking new technologies. The result is a cutting-edge piece of

intelligent technology that retains the unrivalled Grundfos reliability.

MORE THAN A PUMP

IF YOU ARE LOOKING FOR THE BEST

EFFICIENCY ON THE MARKET COMBINED WITH

HIGH INTELLIGENCE AND TRULY FULL RANGE,

LOOK NO FURTHER. THE MAGNA3 IS HERE

THE HIGHEST STANDARDS,

THE GREATEST RESULTS

Ready for range?

MAGNA3 is a truly full-range pump with more than

25 dierent single and twin circulators in cast iron or

stainless steel. We have also increased the maximum

head to 60 Ft and the ow to 550 GPM. Get ready to

specify a perfectly sized circulator pump for any HVAC

AUTOadapt application.

The smart pump

MAGNA3 gives you new opportunities with more

intelligent control modes, optimized building

management communication and a built-in heat

energy meter. It also allows you to save pump throttling

valves in the system. It is fair to say that we have raised

the bar for intelligent pumping.

Eciently the best

The short version is this: MAGNA3 is the most

ecient circulator available on the market today.

The longer version is this: With the lowest Energy

Eciency Index (EEI) in the world, below 0.20, you

can achieve energy savings of up to 75% compared to

a typical installed circulator. With the unique

Autoadapt control these savings can be as much

as 85% and thereby a remarkably fast return on

investment.

Reliable from A to Z

At Grundfos we do not take testing lightly. With 40

years of experience with electronically controlled

pumps and 1 million test hours for the MAGNA3 in

extreme conditions, including alternating pressure

tests, high humidity tests as well as high and low-

temperature tests, we are condent that this pump will

serve you day in and day out for many years to come.

Other ECM Circulators

Proportional pressure mode

Constant pressure mode

AUTOadapt

Constant temperature mode

FLOWadapt

Constant curve mode

The AUTOadapt function continuously adjusts the

proportional pressure curve and automatically

sets a more ecient one, without compromising

comfort demands. With this factory setting, in

80% of the installations no manual adjustments

are needed.

Proportional pressure mode is used in

circulating systems. The pump continuously

adapts its performance to the varying ow

demand.

Constant curve mode is used when there is a

demand for constant ow and constant head.

The pump is adjusted to the desired duty point

making pump throttling valves, which are

traditionally required in this situation, obsolete.

Constant temperature mode is used in variable

ow systems within heating, where a constant

liquid temperature at a user-dened point, is

desired. The pump is in charge of the ow, and

external controller for temperature regulation

are made unnecessary.

Constant pressure mode is suited for variable

ow systems with very low pipe pressure losses,

and in open systems where pipe pressure loss is

subordinate to static head.

FLOWadapt is a combination of AUTOadapt and

FLOWLIMIt. The MAGNA3 continuously monitors

the ow rate ensuring that it is not exceeded. This

will, in some cases, save the cost of a separate

pump throttling valve.

INTRODUCING:

YOUR PERFECT CONTROL MODE

Intelligent control saves time and energy

The MAGNA3 gives you the full range of control mode options you would expect from a state-of-the-art

circulator pump. But the intelligent modes – AUTOadapt and FLOWadapt – set MAGNA3 apart from the

competition. Furthermore, the FLOWLIMIt and Automatic Night Setback control functions are applicable

with all MAGNA3 control modes.

FULLRANGE EFFICIENCY

Full range means perfect t

The extended MAGNA3 range with maximum heads

of 60ft and maximum ows of 550 GPM features more

than 25 single and twin pumps in cast iron or stainless

steel. This means that it is much easier to right-size the

MAGNA3 for any duty point and cut both purchase and

energy costs in the process.

MAGNA is always improving

Grundfos continues to set the pace for circulator pumps

and is the obvious choice if you are looking for the

most energy-ecient solution and fastest return on

investment.

To achieve the groundbreaking MAGNA3 energy

eciency, we have further optimized pump hydraulics

and incorporated our patented dierential pressure

sensor, while switching to a composite rotor can and a

compact stator that minimizes losses in the motor.

The result is a highly ecient and future-proof

circulator exceeding even future energy standards.

The all-purpose circulator

Like its predecessor, MAGNA3 is the ideal pump for

heating and cooling applications as well as domestic

hot water circulation systems. It is designed to handle

liquids down to 14°F, which makes it suitable

for both tough industrial tasks and ground source

heat pump systems (GSHP). Furthermore, the liquid

temperature (14°F to 230°F) is now independent of the

ambient temperature (32°F to 104°F). So whether your

project requires heating or cooling – MAGNA3 is the

pump for you.

INTELLIGENT SOLUTIONS

Built for building management

Optional CIM modules support all common eldbus standards, making MAGNA3 the perfect addition

to any BMS system.

Heat energy meter

The MAGNA3 features a built-in heat energy meter that can monitor system heat energy distribution

and consumption in order to avoid excessive energy bills caused by system imbalances. The heat

energy meter has an accuracy of +/-1% to +/-10%, depending on the duty point, and will save you the

cost of installing a separate energy metering device within your system.

No pump throttling valves

The new FLOWLIMIt function and FLOWadapt control mode allow you to set a maximum ow limit for

your MAGNA3 pump. The pump continuously monitors the ow rate to ensure the desired maximum

ow is not exceeded. This eliminates the need for pump throttling valves and hereby improves

the system’s overall energy-eciency. To meet system ow limitations, the pump will adjust its

performance to a given setpoint, which dramatically cuts energy consumption.

Wireless communication between two single pumps

MAGNA3 is supplied with wireless technology which enables it to connect to another MAGNA3 pump.

Using the built-in wizard, connection to a parallel coupled pump is quick and easily obtained. The two

pumps are now controlled jointly in either cascade mode, alternating mode or pump back-up mode.

More I/O for system intelligence

With the addition of an extra congurable relay and

an analog input, the complete MAGNA3 I/O package

allows for better system monitoring and optimal pump

regulation.

MAGNA3 I/O package

1 x analog input (0-10V/4-20mA) for dierential

pressure sensor, constant temperature control, heat

energy metering or external set point 2 x relay outputs

congurable as alarm, ready or operation 3 x digital

inputs for external start/stop, max. curve and min. curve

Easy optimization

The innovative 3D Work Log and Duty Point Over Time

curve make optimization simple and accurate. The

two new features give you the details of the pump’s

performance since the day it was installed as well as

the details of its operating conditions, such as average

temperature and power consumption. Based on this, it

is easy to nd the optimal replacement pump, perfect

optimization plan or carry out troubleshooting.

Pump Pump throttling valve Energy meter

More than a pump:

The MAGNA3 has a built in energy meter and a ow limiting

function which makes up for a pump throttling valve.

TAKE A CLOSER LOOK

Reliability through generations

The MAGNA3 hardware is a third generation platform

built on Grundfos’ 65 years of pump experience, while

the pump’s new self-protecting electronics prove that

we are still the industry’s electronic pump pioneers.

1 million test hours

At Grundfos, we believe in the value of thorough

testing. The MAGNA3 has been submitted to more

than 1 million test hours in extreme conditions,

including alternating pressure tests, high humidity

tests as well as high and low-temperature tests.
