The unit couples a 7.5 kW drive motor to an axial DN 100 inlet nozzle and a radial DN 80 discharge connection.\u003c\/p\u003e\u003cp\u003emaximum volume discharge provides approx. 2301 L\/Min liquid flow with an upper developed head of approx. 17.1 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 144 kg.\u003c\/p\u003e\u003cp\u003eA dedicated feed of 415 V three-phase powers the 7.5 kW motor, pulling 14.6 Amps during regular operation. Operating limits support liquid temperatures from -25°C to 120°C and maximum system pressures of 16 bar. Flanged pipework attaches via DN 100 inlet and DN 80 outlet ports.\u003c\/p\u003e\u003cp\u003eMotor frame architecture provides IP55 ingress sealing combined with Class F electrical 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\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\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 rated for 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\u003c\/ul\u003e","brand":"Grundfos","offers":[{"title":"Default Title","offer_id":51274493526263,"sku":"93209371","price":8007.34,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/grundfos-nb-80-200-222-cast-iron-7-5-kw-end-suction-centrifugal-pump-with-closed-impeller.png?v=1791359433","url":"https:\/\/foundationpumps.com.au\/products\/grundfos-nb-80-200-222-cast-iron-7-5-kw-end-suction-centrifugal-pump-with-closed-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
