Circulation Pump GRUNDFOS MAGNA1 50-80 F 240 1x230V PN6/10

GRUNDFOS MAGNA1 50-80 F 240 is a circulation pump designed for closed heating and hot-water circulation systems. The pump is flange-mounted and developed for installations requiring reliable water circulation and flow control in boilers, radiators and hydronic loops. It operates from a single-phase 230 V supply and is suitable for systems built to PN6/10 pressure class.

Advantages

The MAGNA1 50-80 F 240 provides stable hydraulic performance with a design optimized for continuous operation in heating circuits. Its flange configuration simplifies installation in larger pipe runs and makes it compatible with standard hydronic connection points. The unit’s single-phase electrical operation and compatibility with common pressure-class systems reduce complexity during replacement or retrofit.

Suitable for

• Central heating circulation loops in residential and commercial buildings
• Hot-water circulation between boiler and radiators
• Hydronic heating installations requiring flange-mounted pumps
• Retrofit or replacement in systems built to PN6/10 pressure class

Key specifications

• Mounting: flange-mounted pump for DN 50–80 connections
• Electrical supply: single-phase 230 V operation
• Pressure rating: suitable for systems designed to PN6/10
• Application: designed for closed heating and hot-water circulation
• Hydraulic range: engineered for medium-duty circulation in heating loops

How to use

Install the pump in the return or supply line according to system design, ensuring flange connections are tightened to the recommended torque and gaskets are correctly positioned to prevent leaks. Connect the single-phase 230 V supply to the pump’s electrical terminals following local wiring regulations and manufacturer wiring diagrams. Fill and vent the hydronic system before commissioning, check for leaks, and verify flow direction and rotation where applicable. Adjust system controls and balancing valves to achieve the required flow and temperature conditions.

Recommendations for use

Use the MAGNA1 50-80 F 240 in closed-loop heating systems with compatible flange dimensions and pressure class. Follow local electrical and plumbing codes during installation, perform routine checks for leaks and proper venting, and schedule preventive maintenance according to operating hours and system conditions to maintain dependable circulation performance.
