It circulates thermal fluids through high-resistance boiler primary circuits and extensive fan coil distribution headers.\u003c\/p\u003e\n\u003cp\u003eAn EN-GJL-250 cast iron casing with a 280 mm face-to-face length houses a pressed AISI 304 stainless steel impeller, stainless rotor can, and bearing plate. The unit handles maximum working pressures of 10 bar (PN 6\/10) and liquid operating temperatures from -10°C to 120°C, weighing 23.1 kg.\u003c\/p\u003e\n\u003cp\u003eThe 3-phase 400-415 V 50 Hz motor has a maximum power input (P1) of 720 W at 1.3 A at top speed, offering three selectable speed curves for system commissioning. Hydraulic performance produces a maximum head of 12 m and a calculated flow rate of 16.3 m³\/h (272 L\/Min) via DN 50 DIN flanged pipe connections.\u003c\/p\u003e\n\u003cp\u003eCeramic radial bearings and a carbon axial bearing operate fully immersed in the circulating fluid, preventing seal wear and shaft leakage. The IPX4D motor casing includes Class H insulation and internal thermal switches for interconnection with motor control centres.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFEATURES\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e12 m maximum head overcomes extensive piping friction in commercial loops\u003c\/li\u003e\n\u003cli\u003eFlow delivery up to 272 L\/Min serves large multi-zone heating headers\u003c\/li\u003e\n\u003cli\u003eThree-phase 400-415 V electrical connection provides balanced current consumption\u003c\/li\u003e\n\u003cli\u003eThree-speed motor selection permits field adjustment without external speed drives\u003c\/li\u003e\n\u003cli\u003eCast iron EN-GJL-250 housing rated for 10 bar maximum operational pressure\u003c\/li\u003e\n\u003cli\u003eCorrosion-resistant AISI 304 stainless steel impeller provides operational longevity\u003c\/li\u003e\n\u003cli\u003eStandard DN 50 four-bolt flange configuration matches EN 1092-2 dimensions\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Grundfos","offers":[{"title":"Default Title","offer_id":51139424813303,"sku":"96402103","price":2747.31,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/grundfos-ups-50-120-f-cast-iron-415v-3-speed-circulator-pump-stainless-steel-impeller.png?v=1789019324","url":"https:\/\/foundationpumps.com.au\/products\/grundfos-ups-50-120-f-cast-iron-415v-3-speed-circulator-pump-stainless-steel-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
