Compared with earlier Model A units, Model B includes the expanded MAGNA3 function set shown in the Model A-B-C data booklet, including differential-temperature control, heat energy monitor, operating log, external sensor input, Grundfos GO communication, CIM\/BMS communication options and multipump functionality.\n\u003c\/p\u003e\n\n\u003ch4\u003eWhy choose MAGNA3 instead of MAGNA1?\u003c\/h4\u003e\n\n\u003cp\u003e\nMAGNA3 is generally chosen where more advanced control, monitoring and communication functions are required. Compared with MAGNA1, MAGNA3 offers a more capable display\/interface and additional functions such as AUTOADAPT, FLOWADAPT, FLOWLIMIT, heat energy monitoring, operating history and broader communication options.\n\u003c\/p\u003e\n\n\u003cp\u003e\nMAGNA1 is usually the simpler, lower-cost option for straightforward duties. MAGNA3 is better where commissioning flexibility, system feedback and advanced control are useful.\n\u003c\/p\u003e\n\n\u003ch4\u003eIs this suitable to replace other DN40 circulators?\u003c\/h4\u003e\n\n\u003cp\u003e\nThis model uses \u003cstrong\u003eDN40 flanged connections\u003c\/strong\u003e with a \u003cstrong\u003e250 mm port-to-port length\u003c\/strong\u003e. Where dimensions and duty are comparable, it can replace other DN40 in-line circulators from brands such as \u003cstrong\u003eWilo, Lowara and KSB\u003c\/strong\u003e, subject to hydraulic duty, flange standard, electrical supply and control compatibility.\n\u003c\/p\u003e\n\n\u003cp\u003e\nThe advantage of an electronically controlled circulator is that it can often be adjusted during commissioning to better match the required duty of the pump being replaced, rather than being locked to one fixed-speed curve.\n\u003c\/p\u003e\n\n\u003ch4\u003eWhat liquids can this pump be used with?\u003c\/h4\u003e\n\n\u003cp\u003e\nMAGNA3 is suitable for thin, clean, non-aggressive liquids that do not contain solid particles or fibres. Typical uses include heating water, chilled water and clean circulation duties.\n\u003c\/p\u003e\n\n\u003cp\u003e\n\u003cstrong\u003eWater\/glycol mixtures may be used\u003c\/strong\u003e up to 50%, but glycol concentration and temperature affect viscosity, performance and pump selection.

This pump is the \u003cstrong\u003ecast iron housing\u003c\/strong\u003e version, not the stainless-steel \u003cstrong\u003eN\u003c\/strong\u003e version. For domestic hot-water applications, Grundfos strongly recommends stainless-steel pumps to reduce corrosion risk.\n\u003c\/p\u003e\n\n\u003cp\u003e\nGrundfos also recommends using MAGNA3 pumps in domestic hot-water systems only where water hardness is below approximately \u003cstrong\u003e14 °dH\u003c\/strong\u003e, and keeping the liquid temperature below \u003cstrong\u003e65 °C\u003c\/strong\u003e to reduce the risk of lime precipitation.
