Powered by a 1.5 kW electric drive, piping connects via an axial DN 80 suction port and a radial DN 65 discharge interface.\u003c\/p\u003e\u003cp\u003eFluid transfer capacity reaches approx. 1226 L\/Min rated displacement and overcomes approx. 9.1 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 56 kg.\u003c\/p\u003e\u003cp\u003eFed by a 415 V three-phase line, the drive draws 3.15 Amps nominal current to produce 1.5 kW mechanical power. 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\u003eDrive housing protection satisfies IP55 requirements with Class F temperature 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\u003eBalanced impeller geometry and shaft construction reduce operational vibration throughout duty range.\u003c\/li\u003e\n\u003cli\u003eVolute casing design incorporates integral base feet for direct mounting to concrete plinths.\u003c\/li\u003e\n\u003cli\u003eInternal wear rings retain hydraulic clearance tolerances throughout long service cycles.\u003c\/li\u003e\n\u003cli\u003eSolid stub shaft supported by sealed ball bearings carries axial and radial loads.\u003c\/li\u003e\n\u003cli\u003eStandard PN16 flanged port interfaces align with EN1092-2 heating and cooling headers.\u003c\/li\u003e\n\u003cli\u003eTotally enclosed fan cooled IEC motor maximum flow of S1 duty cycles in ambient environments up to 40°C.\u003c\/li\u003e\n\u003cli\u003eService-friendly back-pull-out layout enables rotating element servicing without removing pipework.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Grundfos","offers":[{"title":"Default Title","offer_id":51269621350647,"sku":"93209335","price":3961.6,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/grundfos-nb-65-160-165-cast-iron-end-suction-centrifugal-pump-with-closed-impeller.png?v=1791282036","url":"https:\/\/foundationpumps.com.au\/products\/grundfos-nb-65-160-165-cast-iron-end-suction-centrifugal-pump-with-closed-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
