Its internal frequency converter adjusts motor speed to match variable heating and cooling demands.\u003c\/p\u003e\n\u003cp\u003eThe 180 mm port-to-port casing is manufactured from EN-GJL-200 cast iron, housing a engineered composite impeller and canned rotor motor. Designed for 10 bar operational pressures and fluid temperatures between -10°C and 110°C, the pump has a net weight of 4.39 kg.\u003c\/p\u003e\n\u003cp\u003eThe 1-phase 230-240 V ECM motor has a maximum power input (P1) of 8 W to 188 W while electrical input power (P1) operates between 8 W and 188 W with a maximum current of 1.51 A. Peak hydraulic output reaches a flow rate of 5.75 m³\/h (96 L\/Min) and a maximum head of 12 m across 1 1\/2 inch threaded connections.\u003c\/p\u003e\n\u003cp\u003eNine control curves are selectable directly on the front panel, providing proportional pressure, constant pressure, and fixed speed operation. Features include an EEI rating of 0.20, Class F insulation, an IPX4D housing, and integrated fault relay terminals.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFEATURES\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eGenerates 12 m maximum head for demanding high-resistance hydronic circuits\u003c\/li\u003e\n\u003cli\u003ePermanent magnet motor technology delivers an Energy Efficiency Index of 0.20\u003c\/li\u003e\n\u003cli\u003eSelf-modulating power consumption ranges from 9 W to 188 W based on load\u003c\/li\u003e\n\u003cli\u003eCast iron EN-GJL-200 housing built for 10 bar maximum working pressure\u003c\/li\u003e\n\u003cli\u003eEngineered composite impeller offers chemical resistance in glycol circuits\u003c\/li\u003e\n\u003cli\u003eFault relay contact and digital run input enable automated building integration\u003c\/li\u003e\n\u003cli\u003e180 mm installation length fits standard 1 1\/2 inch threaded union connections\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Grundfos","offers":[{"title":"Default Title","offer_id":51139438870775,"sku":"99221215","price":2106.72,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/grundfos-magna1-25-120-cast-iron-variable-speed-circulator-pump-mixing-loops-composite-impeller.png?v=1789019344","url":"https:\/\/foundationpumps.com.au\/products\/grundfos-magna1-25-120-cast-iron-variable-speed-circulator-pump-mixing-loops-composite-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
