It delivers steady circulation through district heating substations and large central plant manifolds.\u003c\/p\u003e\n\u003cp\u003eThe casing is constructed from EN-GJL-250 cast iron at a 340 mm port-to-port dimension, housing an EN 1.4301 stainless steel impeller and aluminium stator shell. The pump is rated for operating pressures up to 10 bar and fluid temperatures between -10°C and 120°C, with a net weight of 28.9 kg.\u003c\/p\u003e\n\u003cp\u003eThe 3 x 400-415 V 50 Hz motor has a maximum power input (P1) of 1150 W (1.15 kW) at 2.15 A on speed 3, with three selectable speed steps. Hydraulic output achieves a calculated flow rate of 27.59 m³\/h (460 L\/Min) with a maximum head of 12 m via DN 65 DIN flanged pipe ports.\u003c\/p\u003e\n\u003cp\u003eLiquid-lubricated ceramic bearings provide continuous rotation without mechanical seal maintenance in closed hydronic loops. The motor includes Class H insulation, an IPX4D splash-proof enclosure, and integral thermal switches for overload monitoring.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFEATURES\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eFlow capacity of 460 L\/Min supplies large commercial heating and cooling headers\u003c\/li\u003e\n\u003cli\u003e12 m maximum head capability overcomes extensive distribution loop resistance\u003c\/li\u003e\n\u003cli\u003eThree switchable speed settings permit hydraulic matching during commissioning\u003c\/li\u003e\n\u003cli\u003eThree-phase 400-415 V motor creates balanced electrical current draw across phases\u003c\/li\u003e\n\u003cli\u003eCast iron EN-GJL-250 pump body built for 10 bar operational pressure (PN 6\/10)\u003c\/li\u003e\n\u003cli\u003eAISI 304 stainless steel impeller resists erosion and cavitation in thermal loops\u003c\/li\u003e\n\u003cli\u003eDN 65 four-bolt flange connections conform to EN 1092-2 piping specifications\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Grundfos","offers":[{"title":"Default Title","offer_id":51139428679927,"sku":"96402280","price":3232.19,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/grundfos-ups-65-120-f-cast-iron-415v-3-speed-circulator-pump-stainless-steel-impeller.png?v=1789019330","url":"https:\/\/foundationpumps.com.au\/products\/grundfos-ups-65-120-f-cast-iron-415v-3-speed-circulator-pump-stainless-steel-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
