The hydraulic assembly is manufactured in AISI 304 stainless steel and supports domestic, civil, garden, irrigation, and industrial utility applications where compact installation and corrosion-resistant construction are important. Its single-phase motor configuration allows operation from standard 230V supply while maintaining continuous-duty performance characteristics.\u003c\/p\u003e\n\n\u003cp\u003eHydraulic capability extends to a maximum head of 28.2 m with flow rates reaching 6.6 m³\/h. The motor develops 1.1 kW rated output with maximum power input of 1.5 kW while operating at 7 A under 230V single-phase supply conditions. A two-pole induction motor operating near 2900 rpm supports stable pressure generation and controlled flow transfer across varying operating demand. Threaded suction and discharge ports in ISO 228\/1 configuration simplify integration into compact pipework systems.\u003c\/p\u003e\n\n\u003cp\u003eFlow movement is managed through a closed impeller arrangement engineered for smooth hydraulic transfer with clean, non-abrasive liquids. The close-coupled motor and hydraulic layout minimizes alignment requirements and reduces overall installation footprint compared with separately coupled assemblies. Stainless steel casing, shaft, impeller, and casing cover components contribute to corrosion resistance and long-term hydraulic consistency during extended operating periods.\u003c\/p\u003e\n\n\u003cp\u003eMechanical sealing uses ceramic alumina and carbon seal faces combined with EPDM elastomer components. Operating capability covers liquid temperatures from -10°C to +90°C with maximum permissible working pressure up to 10 bar. The motor assembly incorporates class F insulation and IP54 protection, while the integrated thermal protector used on NMXM single-phase models supports additional operating safety. Approximate unit weight for this model is 13.6 kg according to the technical data sheet.\u003c\/p\u003e\n\n\u003cstrong\u003eFEATURES\u003c\/strong\u003e\n\u003cul\u003e\n\u003cli\u003eSingle-phase 230V close-coupled centrifugal pump configuration\u003c\/li\u003e\n\u003cli\u003eClosed impeller hydraulic design for stable clean liquid transfer\u003c\/li\u003e\n\u003cli\u003eAISI 304 stainless steel casing, shaft, impeller, and casing cover\u003c\/li\u003e\n\u003cli\u003eISO 228\/1 threaded suction and discharge connection arrangement\u003c\/li\u003e\n\u003cli\u003eCeramic alumina and carbon mechanical seal face combination\u003c\/li\u003e\n\u003cli\u003eEPDM elastomer support components for sealing stability\u003c\/li\u003e\n\u003cli\u003eTwo-pole induction motor operating at approximately 2900 rpm\u003c\/li\u003e\n\u003cli\u003eIntegrated thermal protector with IP54 motor enclosure and class F insulation\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Calpeda","offers":[{"title":"Default Title","offer_id":50755547627767,"sku":"NMXM 25\/90A","price":728.37,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/calpeda-nmxm-25-90a-stainless-steel-thermal-protected-centrifugal-pump-for-utility-water-with-304-ss-impeller.png?v=1778309234","url":"https:\/\/foundationpumps.com.au\/products\/calpeda-nmxm-25-90a-stainless-steel-thermal-protected-centrifugal-pump-for-utility-water-with-304-ss-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
