Its integrated electronics continuously adjust motor rpm in response to zone valve movements throughout the building.\u003c\/p\u003e\n\u003cp\u003eCast iron EN-GJL-200 forms the 180 mm port-to-port pump casing, housing an engineered composite impeller and sealless canned rotor. Rated for 10 bar operating pressure, the unit withstands circulating water and glycol mixtures from -10°C to 110°C with a total net weight of 4.41 kg.\u003c\/p\u003e\n\u003cp\u003eA high-efficiency 1-phase 230-240 V ECM motor has a maximum power input (P1) of 9 W to 92 W with electrical input power (P1) operating from 9 W up to a peak of 92 W at 0.74 A maximum current. Output metrics achieve a flow rate of 4.50 m³\/h (75 L\/Min) with a maximum head of 6 m through 1 1\/2 inch threaded pipe ports.\u003c\/p\u003e\n\u003cp\u003eThe unit incorporates an intuitive push-button interface to select between proportional pressure, constant pressure, and fixed speed curves. Ingress protection is certified to IPX4D with Class F insulation, an EEI of 0.20, and an integrated fault signal relay.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFEATURES\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eElectronically commutated motor with integrated VFD achieves an EEI rating of 0.20\u003c\/li\u003e\n\u003cli\u003eNine selectable operating modes accommodate radiator, underfloor, and constant-flow loops\u003c\/li\u003e\n\u003cli\u003ePower consumption modulates between 9 W and 92 W to minimize electricity usage\u003c\/li\u003e\n\u003cli\u003eCast iron EN-GJL-200 housing built for 10 bar maximum system pressure\u003c\/li\u003e\n\u003cli\u003eComposite impeller offers hydraulic consistency across thermal cycles\u003c\/li\u003e\n\u003cli\u003eBuilt-in fault relay contact and external digital run input for BMS interface\u003c\/li\u003e\n\u003cli\u003eCompact 180 mm port-to-port dimension with standard 1 1\/2 inch threaded connections\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Grundfos","offers":[{"title":"Default Title","offer_id":51139435266295,"sku":"99221217","price":1481.81,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/grundfos-magna1-25-60-cast-iron-variable-speed-circulator-pump-heating-surfaces-composite-impeller.png?v=1789019339","url":"https:\/\/foundationpumps.com.au\/products\/grundfos-magna1-25-60-cast-iron-variable-speed-circulator-pump-heating-surfaces-composite-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
