The unit couples a 0.55 kW drive motor to an axial DN 50 inlet nozzle and a radial DN 32 discharge connection.\u003c\/p\u003e\u003cp\u003eFluid transfer output generates approx. 281 L\/Min Maximum flow with a maximum developed head of approx. 9.8 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 38 kg.\u003c\/p\u003e\u003cp\u003eThe electric drive operates from a 415 V three-phase supply, drawing 1.23 Amps nominal running current to produce 0.55 kW. Operating limits support liquid temperatures from -25°C to 120°C and maximum system pressures of 16 bar. Flanged pipework attaches via DN 50 inlet and DN 32 outlet ports.\u003c\/p\u003e\u003cp\u003eDrive protection includes an IP55 ingress rating combined with Class F motor 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\u003eSolid stub shaft and ball bearing arrangement counteracts operating mechanical stresses.\u003c\/li\u003e\n\u003cli\u003eStandardized PN16 dimensions per EN1092-2 align with facility pipe headers.\u003c\/li\u003e\n\u003cli\u003eIEC standardized electric drive maximum flow of continuous S1 operation in ambients up to 40°C.\u003c\/li\u003e\n\u003cli\u003eBack-pull-out arrangement allows fast access to motor and impeller without disturbing pipework.\u003c\/li\u003e\n\u003cli\u003ePrecision balancing of rotating parts delivers quiet, low-vibration fluid transfer.\u003c\/li\u003e\n\u003cli\u003eHeavy-section cast iron volute with integral mounting pads provides solid base support.\u003c\/li\u003e\n\u003cli\u003eReplaceable wear rings protect casing hydraulics and retain designed pumping clearances.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Grundfos","offers":[{"title":"Default Title","offer_id":51269597167863,"sku":"93208678","price":3072.41,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/grundfos-nb-32-160-170-cast-iron-end-suction-centrifugal-pump-with-closed-impeller.png?v=1791281933","url":"https:\/\/foundationpumps.com.au\/products\/grundfos-nb-32-160-170-cast-iron-end-suction-centrifugal-pump-with-closed-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
