The unit couples a 1.1 kW drive motor to an axial DN 65 inlet nozzle and a radial DN 40 discharge connection.\u003c\/p\u003e\u003cp\u003eDischarge performance generates 373 L\/Min flow volume alongside a 10.17 m maximum developed 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 47 kg.\u003c\/p\u003e\u003cp\u003eEquipped for 415 V three-phase power, the motor requires 2.34 Amps current draw to provide 1.1 kW output. Operating limits support liquid temperatures from -25°C to 120°C and maximum system pressures of 16 bar. Flanged pipework attaches via DN 65 inlet and DN 40 outlet ports.\u003c\/p\u003e\u003cp\u003eDrive frame construction incorporates IP55 ingress protection and Class F 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\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\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\u003c\/ul\u003e","brand":"Grundfos","offers":[{"title":"Default Title","offer_id":51269601951991,"sku":"93209260","price":3658.66,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/grundfos-nb-40-160-177-cast-iron-end-suction-centrifugal-pump-with-closed-impeller.png?v=1791281958","url":"https:\/\/foundationpumps.com.au\/products\/grundfos-nb-40-160-177-cast-iron-end-suction-centrifugal-pump-with-closed-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
