The unit couples a 15 kW drive motor to an axial DN 125 inlet nozzle and a radial DN 100 discharge connection.\u003c\/p\u003e\u003cp\u003ePumping displacement output delivers approx. 3264 L\/Min volumetric flow while reaching an upper head of approx. 27 m. 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 227 kg.\u003c\/p\u003e\u003cp\u003eConnected to 415 V three-phase power, the motor requires 28.7 Amps to produce 15 kW shaft output. Operating limits support liquid temperatures from -25°C to 120°C and maximum system pressures of 16 bar. Flanged pipework attaches via DN 125 inlet and DN 100 outlet ports.\u003c\/p\u003e\u003cp\u003eThe drive casing features IP55 environmental protection combined with 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\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 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\u003c\/ul\u003e","brand":"Grundfos","offers":[{"title":"Default Title","offer_id":51274509156599,"sku":"93207125","price":12595.39,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/grundfos-nb-100-315-279-cast-iron-15-kw-end-suction-centrifugal-pump-with-closed-impeller.png?v=1791359480","url":"https:\/\/foundationpumps.com.au\/products\/grundfos-nb-100-315-279-cast-iron-15-kw-end-suction-centrifugal-pump-with-closed-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
