Product Overview
Engineered for high-resistance hydronic circuits, the Grundfos MAGNA1 32-80 circulator pump provides electronically regulated circulation for air handling unit heating coils, fan coil networks, and multi-zone commercial headers. Its onboard electronics reduce pump speed during partial load conditions.
Constructed with an EN-GJL-200 cast iron housing measuring 180 mm port-to-port, the unit incorporates an engineered composite impeller and maintenance-free canned rotor. It operates at working pressures up to 10 bar and fluid temperatures between -10°C and 110°C, with a net weight of 4.61 kg.
The single-phase 230-240 V ECM motor has a maximum power input (P1) of 9 W to 151 W while electrical power input (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 2 inch threaded connections.
A single push-button interface configures nine operating modes including proportional pressure, constant pressure, and fixed speed curves. The motor features Class F insulation, an IPX4D splash-proof housing, an EEI of 0.20, and fault alarm relay terminals.
