Driven by an electric 37 kW motor assembly, the pump incorporates an axial DN 100 suction port and a radial DN 80 discharge connection.\u003c\/p\u003e\u003cp\u003eLiquid displacement achieves a rated flow volume of 3330 L\/Min alongside a maximum head limit of 46.57 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 305 kg.\u003c\/p\u003e\u003cp\u003eOperating on a 415 V three-phase electrical feed, the drive draws 68.1 Amps rated current to deliver 37 kW output. Operational limits permit media temperatures from -25°C to 120°C under working pressures up to 16 bar. Flanged pipe connections measure DN 100 on the inlet and DN 80 on the outlet.\u003c\/p\u003e\u003cp\u003eEnclosure protection complies with IP55 standards, utilizing Class F insulation materials. 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\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\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\u003c\/ul\u003e","brand":"Grundfos","offers":[{"title":"Default Title","offer_id":51269595463927,"sku":"93209369","price":14557.02,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/grundfos-nb-80-200-200-cast-iron-37-kw-end-suction-centrifugal-pump-with-closed-impeller.png?v=1791281926","url":"https:\/\/foundationpumps.com.au\/products\/grundfos-nb-80-200-200-cast-iron-37-kw-end-suction-centrifugal-pump-with-closed-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
