Circulation Pump GRUNDFOS MAGNA1 50-120F 280 1x230V PN6/10

GRUNDFOS MAGNA1 50-120F 280 is a single-phase circulation pump designed for heating and hot-water recirculation systems. Operating at 1x230V with a PN6/10 flange rating, this MAGNA1 model offers electronically controlled variable-speed operation to match system demand, providing stable flow and reliable pressure control for central heating and recirculation installations.

Advantages

The pump combines an energy-efficient electronically commutated motor with integrated control features to reduce electrical consumption while maintaining required flow. Compact hydraulic design and robust materials ensure long service life in heating circuits. Built-in variable-speed control adapts performance to changing load conditions, improving system stability and reducing noise compared with fixed-speed pumps.

• Интеграция в системы с регулируемыми нагрузками и термостатическими элементами

Key specifications

• Power supply: single-phase 230 V
• Hydraulic connection: flange with PN6/10 rating
• Variable-speed electronically controlled motor for demand-driven flow
• Designed for heating and hot-water recirculation applications
• Compact body suitable for installation in confined plantrooms
• Low-noise operation and reduced energy consumption compared to fixed-speed pumps

How to use

Install the MAGNA1 50-120F 280 inline with the system flow direction indicated on the pump housing and ensure flange connections match the PN6/10 rating of the piping. Commission the pump following system hydraulics: set the control mode and adjust speed settings or let the integrated control adapt automatically to load changes. Verify electrical connection to a single-phase 230 V supply and ensure proper grounding. After installation, purge air from the circuit and check for leaks before normal operation.

Usage recommendations

To optimize energy efficiency and service life, select the pump control mode appropriate to the system (constant pressure, proportional pressure, or manual setting) and perform routine checks for correct rotation, hydraulic balance and absence of air in the system. Use corrosion-resistant piping and maintain water quality within recommended limits for heating systems.
