It integrates into sealed secondary heating circuits and closed cooling water loops where non-potable circulating water remains isolated from atmospheric air.\u003c\/p\u003e\n\u003cp\u003eCast iron EN-GJL-250 forms the 250 mm port-to-port pump housing, paired with an EN 1.4301 stainless steel impeller and an aluminium alloy stator housing. The assembly withstands liquid temperatures between -10°C and 120°C alongside operating pressures to 10 bar (PN 6\/10), with the total net weight measuring 16.6 kg.\u003c\/p\u003e\n\u003cp\u003eA 1-phase 230-240 V 50 Hz motor draws up to 280 W electrical input power (P1) at 1.3 A across three selectable speeds, starting from 250 W in speed 1. Hydraulic output achieves a rated flow of 10.6 m³\/h (177 L\/Min) with a maximum head of 4.24 m, discharging through DN 40 DIN flanged connections.\u003c\/p\u003e\n\u003cp\u003eSealless canned rotor construction utilizes ceramic radial bearings and a carbon axial bearing lubricated directly by the circulating fluid. The electrical enclosure meets IPX4D standards with Class F winding insulation, while internal thermal contacts connect to external control gear for overtemperature shutdown.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFEATURES\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eThree-speed motor selector allows hydraulic commissioning across variable system loads\u003c\/li\u003e\n\u003cli\u003eCast iron EN-GJL-250 body construction rated for 10 bar maximum working pressure\u003c\/li\u003e\n\u003cli\u003eAISI 304 stainless steel impeller delivers corrosion resistance in closed hydronic loops\u003c\/li\u003e\n\u003cli\u003eCanned rotor configuration removes mechanical shaft seals and external fluid leakage\u003c\/li\u003e\n\u003cli\u003eDN 40 four-bolt flange connections conform to EN 1092-2 PN 6\/10 piping standards\u003c\/li\u003e\n\u003cli\u003eLiquid temperature operating capability extends across a wide -10°C to 120°C range\u003c\/li\u003e\n\u003cli\u003eIPX4D splash-proof enclosure with Class F thermal insulation rated for plant rooms\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Grundfos","offers":[{"title":"Default Title","offer_id":51139416916215,"sku":"96401915","price":1800.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/grundfos-ups-40-60-2-f-cast-iron-3-speed-circulator-pump-stainless-steel-impeller.png?v=1789019313","url":"https:\/\/foundationpumps.com.au\/products\/grundfos-ups-40-60-2-f-cast-iron-3-speed-circulator-pump-stainless-steel-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
