Powered by a 7.5 kW electric drive, piping connects via an axial DN 80 suction port and a radial DN 65 discharge interface.\u003c\/p\u003e\u003cp\u003eRated pumping throughput generates 1177 L\/Min liquid output and reaches a 25.11 m head threshold. 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 161 kg.\u003c\/p\u003e\u003cp\u003eConnecting to a 415 V three-phase feed, the drive draws 14.6 Amps while delivering 7.5 kW motor output. 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 motor protection complies with IP55 environmental criteria 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\u003eSolid stub shaft configuration supported by deep groove ball bearings absorbs axial thrust loads.\u003c\/li\u003e\n\u003cli\u003eStandardized EN1092-2 PN16 flange dimensions match standard commercial and district pipe manifolds.\u003c\/li\u003e\n\u003cli\u003eHigh-efficiency IEC electric drive motor rated for S1 continuous operation in ambient conditions up to 40°C.\u003c\/li\u003e\n\u003cli\u003eBack-pull-out construction allows drive and impeller removal without disconnecting suction or discharge lines.\u003c\/li\u003e\n\u003cli\u003ePrecision balanced rotor and runner assemblies minimize operating vibration across all pump speeds.\u003c\/li\u003e\n\u003cli\u003eCast iron volute casing with integral mounting feet absorbs hydraulic forces and pipework stresses.\u003c\/li\u003e\n\u003cli\u003eReplaceable wear rings retain correct internal hydraulic clearances over long operating periods.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Grundfos","offers":[{"title":"Default Title","offer_id":51269626921207,"sku":"93209353","price":9501.47,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/grundfos-nb-65-315-282-cast-iron-7-5-kw-end-suction-centrifugal-pump-with-closed-impeller.png?v=1791282065","url":"https:\/\/foundationpumps.com.au\/products\/grundfos-nb-65-315-282-cast-iron-7-5-kw-end-suction-centrifugal-pump-with-closed-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
