It automatically modulates speed to deliver balanced differential pressure across the system.\u003c\/p\u003e\n\u003cp\u003eThe casing is cast from EN-GJL-200 iron with a 220 mm port-to-port dimension, holding a composite impeller, stainless rotor can, and air-cooled electronic module. Rated for 10 bar working pressure and liquid temperatures from -10°C to 110°C, the complete pump assembly weighs 16.3 kg.\u003c\/p\u003e\n\u003cp\u003eThe single-phase 230-240 V ECM motor has a maximum power input (P1) of 17 W to 370 W and operates from 17 W to a maximum electrical power input (P1) of 370 W at 1.65 A. Hydraulic performance achieves a flow rate of 12.77 m³\/h (213 L\/Min) with a maximum head of 10 m through DN 40 DIN flanged pipe ports.\u003c\/p\u003e\n\u003cp\u003eControl options encompass three proportional pressure curves, three constant pressure curves, and three constant speeds. The unit holds an EEI rating of 0.19, IPX4D ingress protection, Class F insulation, and integrated fault signal 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 elevated resistance across commercial heating coils\u003c\/li\u003e\n\u003cli\u003eHigh flow volume of 213 L\/Min serves central plant distribution headers\u003c\/li\u003e\n\u003cli\u003ePermanent magnet motor design achieves an Energy Efficiency Index (EEI) of 0.19\u003c\/li\u003e\n\u003cli\u003eOperating power self-adjusts between 18 W and 370 W according to circuit demand\u003c\/li\u003e\n\u003cli\u003eCast iron EN-GJL-200 housing rated for 10 bar maximum working pressure\u003c\/li\u003e\n\u003cli\u003eComposite impeller resists chemical corrosion in water-glycol heating 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":51139454959863,"sku":"99221304","price":3079.62,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/grundfos-magna1-40-100-f-cast-iron-variable-speed-circulator-pump-mixing-loops-composite-impeller.png?v=1789019368","url":"https:\/\/foundationpumps.com.au\/products\/grundfos-magna1-40-100-f-cast-iron-variable-speed-circulator-pump-mixing-loops-composite-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
