Range 14 Hydraulic models (11 Single, 3 Twin) Total 37 pumps 115V up to 1HP 208-230V all 14 ° F to 230 ° F Cast Iron and Stainless Water & water/glycol up to 50% Heating, DHW, Solar, Cooling & Geothermal
4
Reliability How long has Grundfos manufactures and sold circulators? How many Alphas/Magnas installed? What is the percentage warranty rate on Magna? Why so reliable? When was the project for Magna3 started? How many hours have the Magna3 been tested?

13
Intelligent Control – FlowADAPT/FLOWLIMIT Flow Limit 0255075100 FLOW LIMIT FLOWADAPT benefits from the advantages of AUTOADAPT, along with the availability to set a maximum flow limit with FLOWLIMIT. Once the desired maximum flow is set, a remarkable energy saving can be achieved. The MAGNA3 continuously monitors the flow rate ensuring that it is not exceeded. This will save the cost of a separate balancing valve. Potential saving compared to an unintelligent pump Potential saving compared to proportional pressure mode Duty point Additional saving with FLOW LIMIT Performance curve

Intelligent Interface – Menu Tabs Show Units in I/P
21
Intelligent Interface – Monitoring MAGNA3 comes with a monitoring function, which makes it possible to keep track of the heat energy distribution and consumption within a system. This avoids excessive energy bills caused by system imbalances. The heat energy meter has an accuracy between +/-1% and +/-10% and makes installing a separate energy metering device within your system superfluous. Temperature input from return pipe
22
Intelligent Interface – Work Log Every duty point and the operational conditions are tracked and stored in the pump. The 3D work log and duty over time curve, provide instant overviews of historical pump performance and operational conditions. The perfect tools for pump optimization, replacement and troubleshooting. Show Units in I/P
