Driven by an electric 0.37 kW motor assembly, the pump incorporates an axial DN 65 suction port and a radial DN 40 discharge connection.\u003c\/p\u003e\u003cp\u003eOperational fluid output delivers approx. 352 L\/Min rated capacity across a maximum head span of approx. 5.6 m. The pump housing is cast in EN-GJL-250 iron with cataphoretic electrocoating. Fluid displacement is driven by a stainless steel impeller and a BQQE mechanical shaft seal. Net product weight measures 33 kg.\u003c\/p\u003e\u003cp\u003eMotor operation on a 415 V three-phase feed requires 0.99 Amps rated current for 0.37 kW shaft output. Operational limits permit media temperatures from -25°C to 120°C under working pressures up to 16 bar. Flanged pipe connections measure DN 65 on the inlet and DN 40 on the outlet.\u003c\/p\u003e\u003cp\u003eThe drive assembly provides an IP55 enclosure rating and Class F thermal insulation. Standard IEC electric drive design requires external motor overload protection. The back-pull-out structural layout permits complete motor and rotating assembly extraction without disconnecting piping headers.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFeatures\u003c\/strong\u003e\u003c\/p\u003e\u003cul\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\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\u003c\/ul\u003e","brand":"Grundfos","offers":[{"title":"Default Title","offer_id":51269600805111,"sku":"93209253","price":3107.01,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/grundfos-nb-40-160-134-cast-iron-end-suction-centrifugal-pump-with-closed-impeller.png?v=1791281951","url":"https:\/\/foundationpumps.com.au\/products\/grundfos-nb-40-160-134-cast-iron-end-suction-centrifugal-pump-with-closed-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
