Its internal speed controller regulates hydraulic pressure as control valves open and close across the circuit.\u003c\/p\u003e\n\u003cp\u003eManufactured 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.\u003c\/p\u003e\n\u003cp\u003eA 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.\u003c\/p\u003e\n\u003cp\u003eControl 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.\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 pressure drops in heat exchanger circuits\u003c\/li\u003e\n\u003cli\u003eDN 32 four-bolt flange configuration matches EN 1092-2 commercial piping specs\u003c\/li\u003e\n\u003cli\u003ePermanent magnet motor technology delivers an Energy Efficiency Index of 0.20\u003c\/li\u003e\n\u003cli\u003eOperating power self-adjusts between 9 W and 151 W according to thermal demand\u003c\/li\u003e\n\u003cli\u003eCast iron EN-GJL-200 pump body built for 10 bar maximum system pressure\u003c\/li\u003e\n\u003cli\u003eComposite impeller resists erosion in closed water and glycol loops\u003c\/li\u003e\n\u003cli\u003eIntegrated fault relay contact and remote digital run\/stop terminals for BMS\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Grundfos","offers":[{"title":"Default Title","offer_id":51139447980279,"sku":"99221275","price":2080.6,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/grundfos-magna1-32-80-f-cast-iron-variable-speed-circulator-pump-heat-pump-systems-composite-impeller.png?v=1789019357","url":"https:\/\/foundationpumps.com.au\/products\/grundfos-magna1-32-80-f-cast-iron-variable-speed-circulator-pump-heat-pump-systems-composite-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
