It operates within multi-storey hydronic heating risers, fan coil distribution loops, and secondary heat exchanger circuits.\u003c\/p\u003e\n\u003cp\u003eThe 250 mm port-to-port casing is manufactured from EN-GJL-250 cast iron, housing an AISI 304 stainless steel impeller, stainless steel rotor can, and bearing plate. Built for working pressures up to 10 bar, the unit accommodates circulating fluid temperatures from -10°C to 120°C with an overall weight of 18.3 kg.\u003c\/p\u003e\n\u003cp\u003eThe motor has a maximum power input (P1) of 470 W at 2.2 A on a 1 x 230-240 V 50 Hz power supply across three manual speed steps. The hydraulic assembly produces a maximum head of 12 m and a rated flow rate of 10.6 m³\/h (177 L\/Min) connected via standard DN 40 DIN flanges.\u003c\/p\u003e\n\u003cp\u003eFluid-lubricated ceramic radial bearings and a carbon axial bearing remove mechanical seal wear inside the canned rotor chamber. Motor windings incorporate Class H insulation inside an IPX4D casing, backed by integrated thermal switches for motor winding protection.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFEATURES\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eThree manual speed selections provide adjustment for high-resistance piping runs\u003c\/li\u003e\n\u003cli\u003eMaximum head capability of 12 m accommodates multi-level heating distribution\u003c\/li\u003e\n\u003cli\u003eCast iron pump housing EN-GJL-250 engineered for closed-loop commercial heating\u003c\/li\u003e\n\u003cli\u003eFabricated AISI 304 stainless steel impeller resists erosive wear under elevated head\u003c\/li\u003e\n\u003cli\u003eDN 40 dual-rated PN 6\/PN 10 flanged ports enable universal installation alignment\u003c\/li\u003e\n\u003cli\u003eThermal winding switches built into the stator connect directly to external trip circuits\u003c\/li\u003e\n\u003cli\u003eCanned rotor motor design operates without variable mechanical shaft seals\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Grundfos","offers":[{"title":"Default Title","offer_id":51139418685687,"sku":"96401942","price":1850.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/grundfos-ups-40-120-f-cast-iron-3-speed-circulator-pump-stainless-steel-impeller.png?v=1789019316","url":"https:\/\/foundationpumps.com.au\/products\/grundfos-ups-40-120-f-cast-iron-3-speed-circulator-pump-stainless-steel-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
