The pump uses a close-coupled configuration that reduces installation footprint while supporting operation with clean liquids that are non-aggressive toward AISI 304 stainless steel materials. Its layout is suited to civil, industrial, irrigation, and general service applications requiring stable continuous circulation.\u003c\/p\u003e\n\n\u003cp\u003eThe hydraulic section develops maximum head up to 28.2 m with flow rates reaching 6.6 m³\/h. Power is supplied through a three-phase 400V induction motor rated at 1.1 kW with operating current of 2.6 A. A two-pole motor arrangement operating near 2900 rpm supports balanced hydraulic transfer and controlled pressure development across continuous-duty operating conditions. Threaded ISO 228\/1 suction and discharge ports simplify integration into circulation pipelines and utility water systems.\u003c\/p\u003e\n\n\u003cp\u003eLiquid movement is managed through a closed impeller arrangement intended for smooth transfer of clean, non-abrasive fluids. Stainless steel construction is used throughout the impeller, shaft, casing, and casing cover, contributing to corrosion resistance and hydraulic consistency during extended operation. The direct-coupled motor and hydraulic assembly minimizes alignment complexity while maintaining simplified servicing access in compact installation environments.\u003c\/p\u003e\n\n\u003cp\u003eCeramic alumina and carbon mechanical seal faces operate together with EPDM elastomer components to support reliable sealing performance. Operating capability includes liquid temperatures from -10°C to +90°C with maximum permissible working pressure up to 10 bar. The motor assembly incorporates class F insulation with IP54 enclosure protection for continuous-duty operation in industrial and utility environments. Inlet connection size is G 1 1\/4 and outlet connection size is G 1.\u003c\/p\u003e\n\n\u003cstrong\u003eFEATURES\u003c\/strong\u003e\n\u003cul\u003e\n\u003cli\u003eTwo-pole induction motor configuration operating at approximately 2900 rpm\u003c\/li\u003e\n\u003cli\u003eCompact close-coupled layout reducing overall installation space\u003c\/li\u003e\n\u003cli\u003eClosed impeller arrangement supporting stable clean liquid circulation\u003c\/li\u003e\n\u003cli\u003eAISI 304 stainless steel hydraulic components throughout the wetted section\u003c\/li\u003e\n\u003cli\u003eThreaded ISO 228\/1 suction and discharge connections for simplified pipe integration\u003c\/li\u003e\n\u003cli\u003eCeramic alumina and carbon seal face combination with EPDM elastomer support\u003c\/li\u003e\n\u003cli\u003eClass F insulated motor assembly with IP54 enclosure protection\u003c\/li\u003e\n\u003cli\u003eContinuous-duty centrifugal pumping configuration for utility circulation systems\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Calpeda","offers":[{"title":"Default Title","offer_id":50755547332855,"sku":"NMX 25\/90A","price":777.92,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/calpeda-nmx-25-90a-stainless-steel-continuous-duty-centrifugal-pump-for-clean-water-with-304-ss-impeller.png?v=1778309190","url":"https:\/\/foundationpumps.com.au\/products\/calpeda-nmx-25-90a-stainless-steel-continuous-duty-centrifugal-pump-for-clean-water-with-304-ss-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
