Product Overview

Providing automated hydraulic regulation, the Grundfos MAGNA1 25-60 circulator pump is suited for underfloor heating manifolds, radiator zones, and fan coil systems. Its integrated electronics continuously adjust motor rpm in response to zone valve movements throughout the building.

Cast iron EN-GJL-200 forms the 180 mm port-to-port pump casing, housing an engineered composite impeller and sealless canned rotor. Rated for 10 bar operating pressure, the unit withstands circulating water and glycol mixtures from -10°C to 110°C with a total net weight of 4.41 kg.

A high-efficiency 1-phase 230-240 V ECM motor has a maximum power input (P1) of 9 W to 92 W with electrical input power (P1) operating from 9 W up to a peak of 92 W at 0.74 A maximum current. Output metrics achieve a flow rate of 4.50 m³/h (75 L/Min) with a maximum head of 6 m through 1 1/2 inch threaded pipe ports.

The unit incorporates an intuitive push-button interface to select between proportional pressure, constant pressure, and fixed speed curves. Ingress protection is certified to IPX4D with Class F insulation, an EEI of 0.20, and an integrated fault signal relay.

FEATURES

  • Electronically commutated motor with integrated VFD achieves an EEI rating of 0.20
  • Nine selectable operating modes accommodate radiator, underfloor, and constant-flow loops
  • Power consumption modulates between 9 W and 92 W to minimize electricity usage
  • Cast iron EN-GJL-200 housing built for 10 bar maximum system pressure
  • Composite impeller offers hydraulic consistency across thermal cycles
  • Built-in fault relay contact and external digital run input for BMS interface
  • Compact 180 mm port-to-port dimension with standard 1 1/2 inch threaded connections
