Product Overview
Designed with a 32 mm bore and 2-inch threaded connections, the Grundfos MAGNA1 32-40 circulator pump provides energy-efficient variable circulation for fan coil loops, radiant ceiling systems, and small chiller circuits. It regulates motor speed dynamically to match real-time heating and cooling demands.
An EN-GJL-200 cast iron pump body with a 180 mm port-to-port dimension encases a composite impeller and maintenance-free canned rotor. Built for 10 bar working pressure, it handles liquid temperatures ranging from -10°C to 110°C, with a net mass of 4.61 kg.
The single-phase 230-240 V ECM motor has a maximum power input (P1) of 9 W to 73 W while electrical power input (P1) modulates between 9 W and 73 W with a maximum current draw of 0.59 A. Hydraulic performance achieves a flow rate of 4.24 m³/h (71 L/Min) against a maximum head of 3.391 m through G 2 inch threaded ports.
The interface allows selection between three proportional pressure curves, three constant pressure curves, and three fixed speeds. The unit meets an EEI rating of 0.20, features Class F insulation with an IPX4D enclosure, and includes digital run/stop and fault relay contacts.

How does the cast iron material construction resist corrosion across closed radiator loops?
Domestic heating circulation on the MAGNA1 32-40 is safeguarded by a sturdy Cast Iron housing with composite impeller and wear-free ceramic bearings.
What supply voltage and motor power kilowatt rating are certified for this hydronic circulator?
Low-consumption electrical mechanics on the Grundfos MAGNA1 32-40 require 240 V to power a drive motor rated at 0.045 kW (45 W) drawing a rated current of 0.59 Amps.
How much working pressure in bar and liquid temperature can this cast iron pump tolerate?
Domestic heating circuit guidelines permit the MAGNA1-32-40 to function at working pressures up to 10 bar in liquids from -10°C to 110°C.
What peak dynamic head does this cast iron circulator deliver across radiator loops?
Providing dependable circulation across domestic heating zones, the Grundfos MAGNA1 32 40 produces a peak dynamic head rating of approximately 4 m.
What delivery flow volume and port connection sizing apply to this compact heating pump?
Supplying residential radiator circuits with 180 mm port-to-port G 2 inch threaded connections, the MAGNA1_32_40 provides a peak fluid delivery volume of approximately 71 L/Min.
