It automatically adjusts speed to deliver proper flow balance across the system.\u003c\/p\u003e\n\u003cp\u003eAn EN-GJL-200 cast iron casing with a 220 mm port-to-port dimension encases a composite impeller and maintenance-free canned rotor motor. Rated for 10 bar working pressure and liquid temperatures from -10°C to 110°C, the complete pump assembly weighs 7.44 kg.\u003c\/p\u003e\n\u003cp\u003eThe single-phase 230-240 V ECM motor has a maximum power input (P1) of 8 W to 175 W and operates between 8 W and a maximum electrical power input (P1) of 175 W at 1.41 A. Output metrics achieve a flow rate of 5.60 m³\/h (93 L\/Min) with a maximum head of 10 m connected via DN 32 DIN flanged pipe ports.\u003c\/p\u003e\n\u003cp\u003eA single push-button on the front panel configures nine operational modes covering proportional, constant pressure, and fixed speed curves. The unit features an EEI rating of 0.20, IPX4D splash-proof protection, Class F insulation, and built-in fault signal monitoring.\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 in multi-level heating circuits\u003c\/li\u003e\n\u003cli\u003eDN 32 four-bolt flanged body enables direct connection to commercial headers\u003c\/li\u003e\n\u003cli\u003eEnergy Efficiency Index of 0.20 reflects permanent magnet ECM motor efficiency\u003c\/li\u003e\n\u003cli\u003ePower consumption self-modulates from 9 W to 175 W based on variable circuit load\u003c\/li\u003e\n\u003cli\u003eCast iron EN-GJL-200 housing rated for 10 bar maximum system pressure\u003c\/li\u003e\n\u003cli\u003eComposite impeller provides longevity in closed-loop water and glycol mixtures\u003c\/li\u003e\n\u003cli\u003eDigital start\/stop input and fault alarm relay output for building supervisory systems\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Grundfos","offers":[{"title":"Default Title","offer_id":51139449159927,"sku":"99221237","price":2392.01,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/grundfos-magna1-32-100-f-cast-iron-variable-speed-circulator-pump-cooling-systems-composite-impeller.png?v=1789019359","url":"https:\/\/foundationpumps.com.au\/products\/grundfos-magna1-32-100-f-cast-iron-variable-speed-circulator-pump-cooling-systems-composite-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
