Its onboard variable frequency drive delivers exact pressure control as circuit valves throttle.\u003c\/p\u003e\n\u003cp\u003eManufactured from EN-GJL-200 cast iron, the 250 mm port-to-port casing holds a precision composite impeller and air-cooled electronic power module. The assembly is rated for 10 bar working pressure and circulating temperatures from -10°C to 110°C, weighing 16 kg.\u003c\/p\u003e\n\u003cp\u003eThe 1-phase 230-240 V 50\/60 Hz ECM motor has a maximum power input (P1) of 16 W to 615 W while electrical input power (P1) draws between 16 W and 615 W with a maximum current of 2.71 A. Hydraulic performance achieves a calculated flow rate of 15.74 m³\/h (262 L\/Min) against a maximum head of 8.707 m through DN 40 DIN flanged ports.\u003c\/p\u003e\n\u003cp\u003eA single push-button interface configures nine operating modes including proportional pressure, constant pressure, and fixed speed curves. The motor features Class F insulation, an IPX4D splash-proof housing, an EEI of 0.18, and fault alarm relay terminals.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFEATURES\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e15 m maximum head overcomes high piping friction in tall commercial buildings\u003c\/li\u003e\n\u003cli\u003eFlow capacity of 262 L\/Min serves central plant heating distribution\u003c\/li\u003e\n\u003cli\u003ePermanent magnet motor design achieves a low Energy Efficiency Index of 0.18\u003c\/li\u003e\n\u003cli\u003eOperating power self-adjusts from 28 W to 615 W based on variable circuit load\u003c\/li\u003e\n\u003cli\u003eCast iron EN-GJL-200 pump casing rated for 10 bar maximum operational 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 terminals and fault relay output facilitate BMS interlocks\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Grundfos","offers":[{"title":"Default Title","offer_id":51139457286391,"sku":"99221306","price":4175.82,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/grundfos-magna1-40-150-f-cast-iron-variable-speed-circulator-pump-heat-pump-systems-composite-impeller.png?v=1789019371","url":"https:\/\/foundationpumps.com.au\/products\/grundfos-magna1-40-150-f-cast-iron-variable-speed-circulator-pump-heat-pump-systems-composite-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
