Its integrated inverter continuously adapts motor rpm to changing thermal loads.\u003c\/p\u003e\n\u003cp\u003eAn EN-GJL-200 cast iron pump body with a 250 mm port-to-port dimension encloses a composite impeller and maintenance-free canned rotor. Built for 10 bar operational pressure, it handles circulating temperatures between -10°C to 110°C, with a total net weight of 16 kg.\u003c\/p\u003e\n\u003cp\u003eThe single-phase 230-240 V ECM motor has a maximum power input (P1) of 15 W to 463 W with electrical input power (P1) operating from 15 W up to a peak of 463 W at 2.05 A maximum current. Peak hydraulic output reaches a flow rate of 14.35 m³\/h (239 L\/Min) and a maximum head of 12 m across DN 40 DIN flanged connections.\u003c\/p\u003e\n\u003cp\u003eNine control modes provide proportional pressure, constant pressure, and fixed speed operation with single-button adjustment. The unit delivers an EEI rating of 0.19, features Class F insulation with an IPX4D enclosure, and incorporates digital run and 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 to service high-resistance commercial risers\u003c\/li\u003e\n\u003cli\u003eHigh flow delivery of 239 L\/Min satisfies large secondary heating headers\u003c\/li\u003e\n\u003cli\u003eHigh-efficiency ECM motor technology achieves a low EEI rating of 0.19\u003c\/li\u003e\n\u003cli\u003ePower consumption modulates between 20 W and 463 W based on circuit resistance\u003c\/li\u003e\n\u003cli\u003eCast iron EN-GJL-200 housing engineered for 10 bar maximum working pressure\u003c\/li\u003e\n\u003cli\u003eComposite impeller construction provides corrosion resistance in hydronic systems\u003c\/li\u003e\n\u003cli\u003eStandard 250 mm port-to-port dimension with DN 40 PN 6\/10 flange holes\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Grundfos","offers":[{"title":"Default Title","offer_id":51139456172279,"sku":"99221305","price":3418.2,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/grundfos-magna1-40-120-f-cast-iron-variable-speed-circulator-pump-heating-surfaces-composite-impeller.png?v=1789019369","url":"https:\/\/foundationpumps.com.au\/products\/grundfos-magna1-40-120-f-cast-iron-variable-speed-circulator-pump-heating-surfaces-composite-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
