Fitted with a 11 kW motor, system piping interfaces through an axial DN 125 suction port and a radial DN 100 discharge flange.\u003c\/p\u003e\u003cp\u003eFluid delivery rating generates approx. 3783 L\/Min volumetric throughput and reaches a approx. 17 m maximum head. Housing construction features cataphoretically coated EN-GJL-250 cast iron, accommodating a stainless steel impeller and a BQQE mechanical seal. Net weight measures 212 kg.\u003c\/p\u003e\u003cp\u003ePulling 22.3 Amps on a 415 V three-phase circuit, the motor assembly develops 11 kW 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 125 inlet and DN 100 outlet.\u003c\/p\u003e\u003cp\u003eDrive frame layout incorporates an IP55 ingress rating and Class F temperature 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\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\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\u003c\/ul\u003e","brand":"Grundfos","offers":[{"title":"Default Title","offer_id":51274506502391,"sku":"92672203","price":9371.51,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/grundfos-nb-100-200-219-cast-iron-11-kw-end-suction-centrifugal-pump-with-closed-impeller.png?v=1791359468","url":"https:\/\/foundationpumps.com.au\/products\/grundfos-nb-100-200-219-cast-iron-11-kw-end-suction-centrifugal-pump-with-closed-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
