Product Overview

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.
Pump status
indicator
The innovative
Grundfos Eye
provides visual
indication of pump
status: pump
running, warning or
alarm.
Perfect insulation
Heating insulation shell that provides optimal thermal
insulation of the pump housing. Delivered as standard, the
insulation shells are perfectly molded to the pump shape to
avoid subsequent time-consuming adjustments.
Sensors make the dierence
Integrated sensor measures dierential
pressure over the pump for increased
eciency. Temperature sensor provides
pump liquid temperature data for
heat energy estimation (add external
sensor to measure return pipe liquid
temperature).
Composite rotor can
Composite rotor can
minimizes power
loss and contributes
to higher energy
eciency.
Neodymium technology rotor
High-performance neodymium magnet
rotor increases motor eciency.
Compact stator
Highly ecient
compact stator
minimizes energy loss.
Improved
hydraulics
Pump hydraulics
have been further
improved through
the use of ow
analysis and 3D
development tools.
Clamp ring
Innovative, specially
designed clamp ring allows
for fast repositioning and
servicing of pump head.
Corrosion protection
Cataphoresis surface
treatment of pump and
stator housing protects
against corrosion.
More data to and from the pump
Three digital inputs, two output relays
and one analog input for external
sensor.
Easy BMS integration
For connection to BMS,
CIM modules are easily
mounted directly in the
control box.
High-quality user
interface
TFT (Thin Film
Transistor) color
display for easy
and intuitive
pump setup.
Easy cabling
Unique power
connection
through plug
connection inside
the control box.
Accessories
Grundfos GO
Grundfos GO gives you intuitive
handheld pump control and full
access to the Grundfos online tools
on the go.
CIM modules
For connection to BMS, CIM modules
with the following eld-bus standards
can be added: LON, Probus, Modbus,
SMS/GSM/GPRS and BACnet. In
addition, the GENIBus is also available.
Insulation shells
for cooling applications
Insulation shells that prevent
condensation and corrosion in air
conditioning and ground source
heat pump systems.
Air-cooling prevents
condensation
Air-cooling in the control
box prevents condensation
problems.
