GRUNDFOS Grundfos Flange Pump MAGNA3 D 65-120 F 340 1x230V PN6/10 No. 97924493 – 97924493

High-efficiency twin circulator pump MAGNA3 D High-efficiency wet-running twin pump made of cast iron with permanent magnet motor (ECM technology) and integrated electronic power adjustment through stepless speed change for pumping clean, low-viscosity media, without solid or long-fiber components that neither chemically nor mechanically attack the pump. Up to and including DN 65 with combination flanges PN 06/10. Twin pump with pump housing made of cast iron and spring-loaded changeover flap for silent changeover between the 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, alternate operation, and efficiency-optimized peak load addition, i.e., parallel operation - Low stock-keeping due to combination 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-adapting curve - FlowLimit function for limiting the max. flow rate in all control modes, e.g., in AutoAdapt = FlowAdapt function - Further control/setting modes: Proportional pressure control Constant pressure control Constant temperature control Constant curve - Media temperatures permanently -10°C to +110°C regardless of the ambient temperature - Automatic night setback for further energy savings - Easiest pump head mounting with clamp band and profile clamp - Commissioning via virtual commissioning assistant - 2 relay outputs for operation and fault messages - 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 recording and storage of all operating points and conditions - Heat quantity and power detection possible via external temperature sensor (accessory) - Context-related operating and setting assistant - Continuous storage of warnings and alarms with date and time - Canned rotor made of composite - Made in Germany
