Its onboard electronics reduce pump speed during partial load conditions.\u003c\/p\u003e\n\u003cp\u003eConstructed 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.\u003c\/p\u003e\n\u003cp\u003eThe 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.\u003c\/p\u003e\n\u003cp\u003eA 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.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFEATURES\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eGenerates 8 m maximum head to overcome coil and piping friction in HVAC loops\u003c\/li\u003e\n\u003cli\u003ePermanent magnet motor technology delivers an Energy Efficiency Index of 0.20\u003c\/li\u003e\n\u003cli\u003ePower consumption self-adjusts between 9 W and 151 W based on thermal demand\u003c\/li\u003e\n\u003cli\u003eCast iron EN-GJL-200 pump casing rated for 10 bar maximum operational pressure\u003c\/li\u003e\n\u003cli\u003eComposite impeller provides hydraulic stability across varying temperature cycles\u003c\/li\u003e\n\u003cli\u003eIntegrated fault relay and digital run\/stop terminals serve BMS integration\u003c\/li\u003e\n\u003cli\u003eStandard 180 mm port-to-port length with 2 inch threaded union fittings\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Grundfos","offers":[{"title":"Default Title","offer_id":51139442671863,"sku":"99221235","price":1872.64,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/grundfos-magna1-32-80-cast-iron-variable-speed-circulator-pump-heating-surfaces-composite-impeller.png?v=1789019349","url":"https:\/\/foundationpumps.com.au\/products\/grundfos-magna1-32-80-cast-iron-variable-speed-circulator-pump-heating-surfaces-composite-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
