Powered by a 0.37 kW electric drive, piping connects via an axial DN 50 suction port and a radial DN 32 discharge interface.\u003c\/p\u003e\u003cp\u003eHydraulic delivery provides a rated flow capacity of 160 L\/Min alongside a maximum head limit of 7.178 m. 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 32 kg.\u003c\/p\u003e\u003cp\u003eElectrical input from a 415 V three-phase connection runs the 0.37 kW motor with an operating draw of 0.99 Amps. Permissible media temperatures range between -25°C to 120°C under system pressures up to 16 bar. Flanged line ports measure DN 50 for suction and DN 32 for discharge.\u003c\/p\u003e\u003cp\u003eProtective specifications incorporate an IP55 enclosure rating and Class F electrical 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\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 rated for 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\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\u003c\/ul\u003e","brand":"Grundfos","offers":[{"title":"Default Title","offer_id":51269596872951,"sku":"93207157","price":2869.52,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/grundfos-nb-32-160-1-172-cast-iron-end-suction-centrifugal-pump-with-closed-impeller.png?v=1791281931","url":"https:\/\/foundationpumps.com.au\/products\/grundfos-nb-32-160-1-172-cast-iron-end-suction-centrifugal-pump-with-closed-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
