Product information

Description

GRUNDFOS MAGNA1 25-40 is a circulator pump engineered for heating and domestic hot water circulation in residential and light commercial hydronic systems. The pump supports continuous circulation and provides stable flow for central heating, radiator circuits and hot water recirculation loops. Its compact wet rotor design and integrated motor electronics enable quiet operation and adaptive performance across typical system demands.

Advantages

The MAGNA1 25-40 delivers energy-efficient operation with variable speed control that adapts to system load, reducing power consumption compared to fixed-speed pumps. The wet rotor construction minimizes maintenance needs and improves reliability. Low noise emissions and a compact footprint facilitate installation in tight plant rooms or underfloor cabinets. Integrated controls simplify commissioning and allow automatic adjustment to changing hydraulic conditions.

Suitable for

  • Central heating circulation in single-family homes and small apartment blocks
  • Domestic hot water recirculation to reduce wait times and water waste
  • Hydronic systems with radiators, underfloor heating manifolds and boiler loops

Key specifications

  • Nominal diameter: DN25 connection size suitable for standard heating pipework
  • Maximum head: up to 4.0 meters for typical system pressure requirements
  • Flow rate range: suitable for residential and light commercial circulation duties
  • Motor type: electronically controlled variable speed motor for adaptive control
  • Construction: wet rotor circulator for compactness and low maintenance
  • Noise level: low operational noise appropriate for indoor installation

How to use

Install the MAGNA1 25-40 in-line with the heating or hot water circulation loop following local plumbing and safety regulations. Ensure correct orientation and secure flange or threaded connections to avoid leaks. Connect the electrical supply to the integrated motor control according to wiring instructions and set operating mode or let the pump run in automatic adjustment mode. After installation, purge air from the system and verify flow, temperature and pressure to confirm correct operation.

Usage recommendations

For optimal performance, match pump settings to system hydraulic characteristics and perform periodic checks for leakage, correct flow and any unusual noise. Use water treatment and filtration in closed heating systems where recommended, and follow local codes and manufacturer guidance for electrical connections and maintenance intervals.
