GRUNDFOS Grundfos Flange Pump MAGNA3 D 40-120 F 250 1x230V PN6/10 No. 97924465 – 97924465

High-efficiency twin-head circulator pump MAGNA3 D High-efficiency wet-running twin-head pump made of cast iron with permanent magnet motor (ECM technology) and integrated electronic power adjustment through stepless speed control for pumping clean, low-viscosity media, free of solid or long-fibered components, that will not chemically or mechanically attack the pump. Up to and including DN 65 with combi-flanges PN 06/10. Twin-head pump with pump housing made of cast iron and spring-loaded changeover flap for silent switching between pump heads. Synchronous motors with ECM technology and highest efficiencies, high starting torque and integrated full motor protection. Functions and Features: - EEI <= 0.20 Best in Class - Operating modes: standby, duty/standby, and efficiency-optimized peak load addition, i.e., parallel operation - Low stock-keeping due to combi-flanges PN 06/10, also available in PN 16 version - Cataphoresis coating for highest corrosion resistance and longevity - AutoAdapt function finds the optimal setting through self-adaptive curve - FlowLimit function for limiting the max. flow rate in all control modes, including AutoAdapt = FlowAdapt function - Further control/setting modes: Proportional pressure control Constant pressure control Constant temperature control Constant curve - Media temperatures continuously -10°C to +110°C regardless of ambient temperature - Automatic night setback for further energy saving - Easiest pump head assembly with clamp band and profile clamp - Commissioning via virtual commissioning assistant - 2 relay outputs for operation and fault indication - Plug-in modules in the terminal box for connection to building management systems available as accessories. The following protocols are available: GeniBus, ModBus, LonWorks, ProfiBus, BacNet. - Wireless communication via radio to Grundfos GO remote control and diagnostic device as well as between the two pump heads -> No wiring effort - Intuitive user interface with TFT monitor and status indicator for operation, warning, alarm - Operation optimization through continuous acquisition and storage of all operating points and conditions - Heat quantity and power measurement possible with external temperature sensor (accessory) - Context-related operation and setting assistant - Continuous storage of warnings and alarms with date and time - Composite can - Made in Germany
