It regulates motor speed dynamically to match real-time heating and cooling demands.\u003c\/p\u003e\n\u003cp\u003eAn EN-GJL-200 cast iron pump body with a 180 mm port-to-port dimension encases a composite impeller and maintenance-free canned rotor. Built for 10 bar working pressure, it handles liquid temperatures ranging from -10°C to 110°C, with a net mass of 4.61 kg.\u003c\/p\u003e\n\u003cp\u003eThe single-phase 230-240 V ECM motor has a maximum power input (P1) of 9 W to 73 W while electrical power input (P1) modulates between 9 W and 73 W with a maximum current draw of 0.59 A. Hydraulic performance achieves a flow rate of 4.24 m³\/h (71 L\/Min) against a maximum head of 3.391 m through G 2 inch threaded ports.\u003c\/p\u003e\n\u003cp\u003eThe interface allows selection between three proportional pressure curves, three constant pressure curves, and three fixed speeds. The unit meets an EEI rating of 0.20, features Class F insulation with an IPX4D enclosure, and includes digital run\/stop and fault relay contacts.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFEATURES\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003ePermanent magnet ECM motor with integrated inverter achieves an EEI of 0.20\u003c\/li\u003e\n\u003cli\u003eNine selectable control modes provide setup for variable and constant flow loops\u003c\/li\u003e\n\u003cli\u003ePower consumption modulates from 9 W to 73 W based on circuit valve positions\u003c\/li\u003e\n\u003cli\u003eCast iron EN-GJL-200 housing engineered for 10 bar maximum operating pressure\u003c\/li\u003e\n\u003cli\u003eComposite impeller provides corrosion resistance in closed hydronic systems\u003c\/li\u003e\n\u003cli\u003eDigital start\/stop input and fault alarm relay output for building supervisory systems\u003c\/li\u003e\n\u003cli\u003e180 mm port-to-port body with 2 inch threaded connection ports\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Grundfos","offers":[{"title":"Default Title","offer_id":51139440312567,"sku":"99221233","price":1534.06,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/grundfos-magna1-32-40-cast-iron-variable-speed-circulator-pump-heating-surfaces-composite-impeller.png?v=1789019346","url":"https:\/\/foundationpumps.com.au\/products\/grundfos-magna1-32-40-cast-iron-variable-speed-circulator-pump-heating-surfaces-composite-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
