Product Overview
The Grundfos MAGNA1 32-80 F circulator pump combines a flanged body with high head capability to serve plate heat exchanger feeds, fan coil headers, and multi-zone heating risers. Its internal speed controller regulates hydraulic pressure as control valves open and close across the circuit.
Manufactured from EN-GJL-200 cast iron, the 220 mm port-to-port casing holds a precision composite impeller and air-cooled electronic power module. The assembly is rated for 10 bar operating pressure and circulating temperatures from -10°C to 110°C, weighing 7.41 kg.
A 1-phase 230-240 V ECM motor has a maximum power input (P1) of 9 W to 151 W while electrical input power (P1) modulates between 9 W and 151 W with a maximum current of 1.22 A. Peak hydraulic output provides maximum a flow rate of 5.39 m³/h (90 L/Min) against a maximum head of 5.724 m through DN 32 DIN flanged connections.
Control options encompass three proportional pressure settings, three constant pressure curves, and three constant speed curves. Certified to an EEI rating of 0.20 with Class F insulation and an IPX4D enclosure, the pump includes digital run terminals and a fault alarm relay.
FEATURES
- Generates 8 m maximum head to overcome pressure drops in heat exchanger circuits
- DN 32 four-bolt flange configuration matches EN 1092-2 commercial piping specs
- Permanent magnet motor technology delivers an Energy Efficiency Index of 0.20
