MAGNA3 65-120 FMAGNA3 - More than a pumpWith its unrivalled efficiency all-encompassing range
and built-in communication capabilities plus functionalities replacing system components the
MAGNA3 is ideal for engineers and specifiers looking to create high-performance systems for
buildings. This pump in the Grundfos Master Class will fit both heating and cooling
applications perfectly making it the obvious choice for almost any building project - old or
new.The MAGNA3 is of the canned-rotor type i.e. pump and motor form an integral unit without
shaft seal and with only two gaskets for sealing. The bearings are lubricated by the pumped
liquid.The innovative clamp with only one screw enables easy repositioning of the pump head.
The MAGNA3 is a pump with no maintenance requirements and with extremely low Life Cycle
Cost.The pump is characterised by the following:• controller integrated in the control box•
control panel with TFT display on the control box• control box prepared for optional CIM
modules• built-in differential-pressure and temperature sensor• cast-iron pump housing
(depending on model)• carbon-fibre-reinforced composite rotor can• stainless-steel bearing
plate and rotor cladding• aluminium alloy stator housing• air-cooled power electronicsThe
MAGNA3 is a single-phase pump.Characteristic features• AUTOADAPT.• FLOWADAPT and FLOWLIMIT
(more than a pump function as it reduces the need for pump throttling valves).•
Proportional-pressure control.• Constant-pressure control.• Constant-temperature control.•
Constant-curve duty.• Max. or min. curve duty.• Automatic Night Setback.• No external motor
protection required.• Insulating shells supplied with single-head pumps for heating systems.•
Large temperature range where the liquid temperature and the ambient temperature are
independent of each other.CommunicationThe MAGNA3 enables communication via the following:•
