Fitted with a 1.1 kW motor, system piping interfaces through an axial DN 80 suction port and a radial DN 65 discharge flange.\u003c\/p\u003e\u003cp\u003eDischarge flow capacity achieves approx. 1279 L\/Min operational delivery across a approx. 6.6 m maximum head. Housing construction features cataphoretically coated EN-GJL-250 cast iron, accommodating a stainless steel impeller and a BQQE mechanical seal. Net weight measures 53 kg.\u003c\/p\u003e\u003cp\u003eMechanical power of 1.1 kW is developed from a 415 V three-phase supply pulling 2.34 Amps running current. Fluid temperature capabilities range from -25°C to 120°C under working pressure limits up to 16 bar. Flange interfaces are dimensioned at DN 80 inlet and DN 65 outlet.\u003c\/p\u003e\u003cp\u003eElectric motor framing conforms to IP55 environmental standards with Class F thermal insulation. External motor overload protection must be provided by the installer. The back-pull-out construction allows extraction of the motor and rotating components without disturbing suction or discharge pipe connections.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFeatures\u003c\/strong\u003e\u003c\/p\u003e\u003cul\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\u003cli\u003eSolid stub shaft and ball bearing arrangement counteracts operating mechanical stresses.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Grundfos","offers":[{"title":"Default Title","offer_id":51269619613943,"sku":"93209330","price":3674.55,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/grundfos-nb-65-125-144-cast-iron-end-suction-centrifugal-pump-with-closed-impeller.png?v=1791282027","url":"https:\/\/foundationpumps.com.au\/products\/grundfos-nb-65-125-144-cast-iron-end-suction-centrifugal-pump-with-closed-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
