It automatically balances pressure across modulating thermostatic zones.\u003c\/p\u003e\n\u003cp\u003eThe 180 mm port-to-port casing is manufactured from EN-GJL-200 cast iron, housing a corrosion-resistant composite impeller and air-cooled electronic power module. Rated for 10 bar working pressure, it accommodates fluid temperatures from -10°C to 110°C with a net weight of 4.63 kg.\u003c\/p\u003e\n\u003cp\u003eOperating on a 1-phase 230-240 V 50\/60 Hz supply, the ECM motor has a maximum power input (P1) of 8 W to 175 W while electrical input power (P1) draws between 8 W and 175 W at 1.41 A maximum current. Output metrics reach a calculated flow rate of 5.60 m³\/h (93 L\/Min) with a maximum head of 10 m across G 2 inch threaded ports.\u003c\/p\u003e\n\u003cp\u003eControl options encompass three proportional pressure curves, three constant pressure curves, and three constant speed steps. The pump meets an EEI rating of 0.20, provides Class F winding insulation inside an IPX4D housing, and includes digital input and fault relay contacts.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFEATURES\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e10 m maximum head overcomes high pressure drops in multi-storey radiant systems\u003c\/li\u003e\n\u003cli\u003eECM permanent magnet motor with integrated inverter achieves an EEI rating of 0.20\u003c\/li\u003e\n\u003cli\u003eSelf-regulating power input ranges from 9 W to 175 W depending on valve positions\u003c\/li\u003e\n\u003cli\u003eCast iron EN-GJL-200 housing engineered for 10 bar maximum system pressure\u003c\/li\u003e\n\u003cli\u003eComposite impeller provides longevity in treated water and glycol mixtures\u003c\/li\u003e\n\u003cli\u003eDigital start\/stop terminals and fault relay output facilitate BMS interlocks\u003c\/li\u003e\n\u003cli\u003e180 mm port-to-port body with standard 2 inch threaded pipe connections\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Grundfos","offers":[{"title":"Default Title","offer_id":51139444015351,"sku":"99221236","price":2116.13,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/grundfos-magna1-32-100-cast-iron-variable-speed-circulator-pump-mixing-loops-composite-impeller.png?v=1789019351","url":"https:\/\/foundationpumps.com.au\/products\/grundfos-magna1-32-100-cast-iron-variable-speed-circulator-pump-mixing-loops-composite-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
