Driven by an electric 1.1 kW motor assembly, the pump incorporates an axial DN 65 suction port and a radial DN 40 discharge connection.\u003c\/p\u003e\u003cp\u003eHydraulic flow rating achieves 427 L\/Min volume and develops a maximum head elevation of 10.17 m. The pump housing is cast in EN-GJL-250 iron with cataphoretic electrocoating. Fluid displacement is driven by a stainless steel impeller and a BQQE mechanical shaft seal. Net product weight measures 53 kg.\u003c\/p\u003e\u003cp\u003eOperating current draws 2.34 Amps across a 415 V three-phase electrical feed to yield 1.1 kW drive power. Operational limits permit media temperatures from -25°C to 120°C under working pressures up to 16 bar. Flanged pipe connections measure DN 65 on the inlet and DN 40 on the outlet.\u003c\/p\u003e\u003cp\u003eThe motor frame features an IP55 protection rating and Class F thermal insulation. Standard IEC electric drive design requires external motor overload protection. The back-pull-out structural layout permits complete motor and rotating assembly extraction without disconnecting piping headers.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFeatures\u003c\/strong\u003e\u003c\/p\u003e\u003cul\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\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\u003c\/ul\u003e","brand":"Grundfos","offers":[{"title":"Default Title","offer_id":51269602541815,"sku":"93209263","price":3885.86,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/grundfos-nb-40-200-198-cast-iron-end-suction-centrifugal-pump-with-closed-impeller.png?v=1791281963","url":"https:\/\/foundationpumps.com.au\/products\/grundfos-nb-40-200-198-cast-iron-end-suction-centrifugal-pump-with-closed-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
