It delivers high discharge pressure while modulating motor speed to minimize power consumption.\u003c\/p\u003e\n\u003cp\u003eThe casing is cast from EN-GJL-200 iron with a 250 mm port-to-port dimension, housing an engineered composite impeller, stainless rotor can, and air-cooled electronic power module. Rated for 10 bar working pressure, it handles fluid temperatures from -10°C to 110°C, weighing 16 kg.\u003c\/p\u003e\n\u003cp\u003eOperating on a 1-phase 230-240 V supply, the ECM motor has a maximum power input (P1) of 16 W to 615 W while electrical input power (P1) consumes between 16 W and 615 W with a maximum current of 2.71 A. Hydraulic delivery achieves a flow rate of 15.76 m³\/h (263 L\/Min) with a maximum head of 18 m through DN 40 DIN flanged connections.\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 0.18, 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\u003eMaximum 8.755 m of head capability overcomes steep resistance in high-rise buildings\u003c\/li\u003e\n\u003cli\u003eMaximum flow volume of 263 L\/Min provides thermal capacity for central plant loops\u003c\/li\u003e\n\u003cli\u003eECM permanent magnet motor with integrated inverter achieves an EEI rating of 0.18\u003c\/li\u003e\n\u003cli\u003eSelf-regulating power input ranges from 28 W to 615 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\u003c\/ul\u003e","brand":"Grundfos","offers":[{"title":"Default Title","offer_id":51139458892023,"sku":"99221307","price":4801.78,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/grundfos-magna1-40-180-f-cast-iron-variable-speed-circulator-pump-cooling-systems-composite-impeller.png?v=1789019374","url":"https:\/\/foundationpumps.com.au\/products\/grundfos-magna1-40-180-f-cast-iron-variable-speed-circulator-pump-cooling-systems-composite-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
