The unit couples a 11 kW drive motor to an axial DN 80 inlet nozzle and a radial DN 65 discharge connection.\u003c\/p\u003e\u003cp\u003eHydraulic fluid rating attains 1450 L\/Min volumetric delivery against a 30.83 m maximum head. Volute casing construction features EN-GJL-250 cast iron with cataphoretic electrocoating, paired with a stainless steel impeller and BQQE shaft seal. Product net weight equals 214 kg.\u003c\/p\u003e\u003cp\u003eThree-phase electrical input at 415 V operates the 11 kW drive at a current draw of 22.3 Amps. Operating limits support liquid temperatures from -25°C to 120°C and maximum system pressures of 16 bar. Flanged pipework attaches via DN 80 inlet and DN 65 outlet ports.\u003c\/p\u003e\u003cp\u003eEnclosure sealing integrity meets IP55 protection requirements with Class F thermal insulation. Standard motor installation requires external electrical overload protection. The back-pull-out design allows complete drive and rotating assembly extraction while leaving the casing secured to distribution pipework.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFeatures\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eEN1092-2 flanged connections conform to standard PN16 pipework dimensions.\u003c\/li\u003e\n\u003cli\u003eContinuous duty S1 rated electric drive motor operates in ambient temperatures up to 40°C.\u003c\/li\u003e\n\u003cli\u003eBack-pull-out layout permits motor and impeller servicing without breaking pipe connections.\u003c\/li\u003e\n\u003cli\u003eIntegral casing support feet provide direct anchoring to plant room inertia bases and plinths.\u003c\/li\u003e\n\u003cli\u003ePrecision balanced rotating components reduce hydraulic noise and mechanical shaft deflection.\u003c\/li\u003e\n\u003cli\u003eRenewable casing wear rings retain pump efficiency and avoid direct volute casing wear.\u003c\/li\u003e\n\u003cli\u003eSolid shaft assembly with sealed ball bearings absorbs operational hydraulic and radial forces.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Grundfos","offers":[{"title":"Default Title","offer_id":51269627478263,"sku":"93209354","price":10932.02,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/grundfos-nb-65-315-314-cast-iron-11-kw-end-suction-centrifugal-pump-with-closed-impeller.png?v=1791282067","url":"https:\/\/foundationpumps.com.au\/products\/grundfos-nb-65-315-314-cast-iron-11-kw-end-suction-centrifugal-pump-with-closed-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
