Fitted with a 1.5 kW motor, system piping interfaces through an axial DN 80 suction port and a radial DN 65 discharge flange.\u003c\/p\u003e\u003cp\u003eRated liquid throughput provides approx. 994 L\/Min operational flow with a maximum head elevation of approx. 9.8 m. Housing construction features cataphoretically coated EN-GJL-250 cast iron, accommodating a stainless steel impeller and a BQQE mechanical seal. Net weight measures 68 kg.\u003c\/p\u003e\u003cp\u003eIncoming power at 415 V three-phase operates the drive at 3.15 Amps for 1.5 kW motor shaft output. Fluid temperature capabilities range from -25°C to 120°C under working pressure limits up to 16 bar. Flange interfaces are dimensioned at DN 80 inlet and DN 65 outlet.\u003c\/p\u003e\u003cp\u003eThe outer casing features IP55 ingress sealing and Class F electrical insulation. External motor overload protection must be provided by the installer. The back-pull-out construction allows extraction of the motor and rotating components without disturbing suction or discharge pipe connections.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFeatures\u003c\/strong\u003e\u003c\/p\u003e\u003cul\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 maximum flow of 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\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\u003c\/ul\u003e","brand":"Grundfos","offers":[{"title":"Default Title","offer_id":51269622464759,"sku":"93209340","price":4692.77,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/grundfos-nb-65-200-170-cast-iron-end-suction-centrifugal-pump-with-closed-impeller.png?v=1791282041","url":"https:\/\/foundationpumps.com.au\/products\/grundfos-nb-65-200-170-cast-iron-end-suction-centrifugal-pump-with-closed-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
