Driven by an electric 22 kW motor assembly, the pump incorporates an axial DN 100 suction port and a radial DN 80 discharge connection.\u003c\/p\u003e\u003cp\u003eOperational flow delivery attains approx. 3016 L\/Min maximum throughput and develops approx. 40.3 m maximum head elevation. 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 310 kg.\u003c\/p\u003e\u003cp\u003eRunning on three-phase 415 V power, the unit draws 42.2 Amps rated running current for 22 kW power. 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\u003eDrive housing architecture conforms to IP55 ingress criteria and Class F winding 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\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 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\u003c\/ul\u003e","brand":"Grundfos","offers":[{"title":"Default Title","offer_id":51274504438007,"sku":"93209378","price":13544.41,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/grundfos-nb-80-315-334-cast-iron-22-kw-end-suction-centrifugal-pump-with-closed-impeller.png?v=1791359455","url":"https:\/\/foundationpumps.com.au\/products\/grundfos-nb-80-315-334-cast-iron-22-kw-end-suction-centrifugal-pump-with-closed-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
