Coupled to a 1.1 kW motor drive, fluid enters through an axial DN 80 suction port and exits through a radial DN 65 discharge flange.\u003c\/p\u003e\u003cp\u003eHydraulic capacity delivers 870 L\/Min volumetric flow against an upper head limit of 5.739 m. Constructed with an EN-GJL-250 cast iron volute protected by cataphoretic electrocoating, internal hydraulics feature a stainless steel impeller and BQQE mechanical shaft seal. Net weight is 53 kg.\u003c\/p\u003e\u003cp\u003ePower consumption reaches 2.34 Amps on a 415 V three-phase connection to drive the 1.1 kW motor. Working tolerances accommodate fluid temperatures spanning -25°C to 120°C at pressures reaching 16 bar. Flanged connections feature DN 80 inlet and DN 65 outlet dimensions.\u003c\/p\u003e\u003cp\u003eMotor enclosure construction provides an IP55 ingress rating and Class F insulation. Because built-in thermal protection is not included, external motor overload protection must be supplied. Maintenance is streamlined via a back-pull-out arrangement allowing rotating element removal while the casing remains connected to piping.\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":51269620760823,"sku":"93209333","price":3911.11,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/grundfos-nb-65-160-149-cast-iron-end-suction-centrifugal-pump-with-closed-impeller.png?v=1791282033","url":"https:\/\/foundationpumps.com.au\/products\/grundfos-nb-65-160-149-cast-iron-end-suction-centrifugal-pump-with-closed-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
