Coupled to a 0.75 kW motor drive, fluid enters through an axial DN 50 suction port and exits through a radial DN 32 discharge flange.\u003c\/p\u003e\u003cp\u003eHydraulic output attains a Maximum flow volume of approx. 269 L\/Min while developing a approx. 13 m maximum head threshold. 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 45 kg.\u003c\/p\u003e\u003cp\u003eRunning on a 415 V three-phase circuit, the motor assembly draws 1.6 Amps to produce 0.75 kW shaft output. Working tolerances accommodate fluid temperatures spanning -25°C to 120°C at pressures reaching 16 bar. Flanged connections feature DN 50 inlet and DN 32 outlet dimensions.\u003c\/p\u003e\u003cp\u003eEnvironmental protection meets IP55 requirements alongside Class F electrical 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\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\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 maximum flow of S1 duty cycles in ambient environments up to 40°C.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Grundfos","offers":[{"title":"Default Title","offer_id":51269598576887,"sku":"93208698","price":3476.33,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/grundfos-nb-32-200-197-cast-iron-end-suction-centrifugal-pump-with-closed-impeller.png?v=1791281941","url":"https:\/\/foundationpumps.com.au\/products\/grundfos-nb-32-200-197-cast-iron-end-suction-centrifugal-pump-with-closed-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
