Powered by a 3 kW electric drive, piping connects via an axial DN 80 suction port and a radial DN 65 discharge interface.\u003c\/p\u003e\u003cp\u003ePumping discharge performance attains 858 L\/Min volumetric flow against a 12.88 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 115 kg.\u003c\/p\u003e\u003cp\u003eElectrical hookup to a 415 V three-phase circuit draws 6.23 Amps current for 3 kW power generation. 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 unit sealing satisfies IP55 enclosure standards, utilizing Class F winding 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\u003eIEC standardized electric drive rated for continuous S1 operation in ambients up to 40°C.\u003c\/li\u003e\n\u003cli\u003eBack-pull-out arrangement allows fast access to motor and impeller without disturbing pipework.\u003c\/li\u003e\n\u003cli\u003ePrecision balancing of rotating parts delivers quiet, low-vibration fluid transfer.\u003c\/li\u003e\n\u003cli\u003eHeavy-section cast iron volute with integral mounting pads provides solid base support.\u003c\/li\u003e\n\u003cli\u003eReplaceable wear rings protect casing hydraulics and retain designed pumping clearances.\u003c\/li\u003e\n\u003cli\u003eSolid stub shaft and ball bearing arrangement counteracts operating mechanical stresses.\u003c\/li\u003e\n\u003cli\u003eStandardized PN16 dimensions per EN1092-2 align with facility pipe headers.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Grundfos","offers":[{"title":"Default Title","offer_id":51269623873783,"sku":"93209348","price":6354.26,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/grundfos-nb-65-250-215-cast-iron-3-kw-end-suction-centrifugal-pump-with-closed-impeller.png?v=1791282050","url":"https:\/\/foundationpumps.com.au\/products\/grundfos-nb-65-250-215-cast-iron-3-kw-end-suction-centrifugal-pump-with-closed-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
