Powered by a 0.55 kW electric drive, piping connects via an axial DN 80 suction port and a radial DN 65 discharge interface.\u003c\/p\u003e\u003cp\u003eHydraulic delivery rating attains approx. 995 L\/Min volumetric throughput with a approx. 3.7 m maximum head. A cataphoretically coated EN-GJL-250 cast iron casing houses the precision stainless steel impeller and BQQE mechanical shaft seal. Total net product weight measures 45 kg.\u003c\/p\u003e\u003cp\u003eDrive power of 0.55 kW is produced across a 415 V three-phase connection at a draw of 1.23 Amps. Permissible media temperatures range between -25°C to 120°C under system pressures up to 16 bar. Flanged line ports measure DN 80 for suction and DN 65 for discharge.\u003c\/p\u003e\u003cp\u003ePhysical frame protection incorporates an IP55 ingress rating and Class F insulation. The motor requires external overload protection in the electrical control panel. A back-pull-out mechanical design enables service personnel to extract the impeller and drive assembly without dismantling pipe flanges.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFeatures\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eRenewable casing wear rings retain pump efficiency and avoid direct volute casing wear.\u003c\/li\u003e\n\u003cli\u003eSolid shaft assembly with sealed ball bearings absorbs operational hydraulic and radial forces.\u003c\/li\u003e\n\u003cli\u003eEN1092-2 flanged connections conform to standard PN16 pipework dimensions.\u003c\/li\u003e\n\u003cli\u003eContinuous duty S1 rated electric drive motor operates in ambient temperatures up to 40°C.\u003c\/li\u003e\n\u003cli\u003eBack-pull-out layout permits motor and impeller servicing without breaking pipe connections.\u003c\/li\u003e\n\u003cli\u003eIntegral casing support feet provide direct anchoring to plant room inertia bases and plinths.\u003c\/li\u003e\n\u003cli\u003ePrecision balanced rotating components reduce hydraulic noise and mechanical shaft deflection.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Grundfos","offers":[{"title":"Default Title","offer_id":51269615354103,"sku":"93209325","price":3356.65,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/grundfos-nb-65-125-120-cast-iron-end-suction-centrifugal-pump-with-closed-impeller.png?v=1791282022","url":"https:\/\/foundationpumps.com.au\/products\/grundfos-nb-65-125-120-cast-iron-end-suction-centrifugal-pump-with-closed-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
