The hydraulic assembly is manufactured in AISI 304 stainless steel, allowing the unit to operate reliably with clean liquids that are non-aggressive toward stainless steel materials. Its compact direct-coupled construction helps reduce installation space while supporting integration into civil, industrial, irrigation, utility, and process support systems where stable circulation performance is required.\u003c\/p\u003e\n\n\u003cp\u003eHydraulic performance reaches up to 18.1 m maximum head with flow rates extending to 5.4 m³\/h. The pump is driven by a three-phase 400V induction motor rated at 0.55 kW with operating current of 1.7 A. Operating speed is approximately 2900 rpm through a two-pole motor configuration, supporting smooth pressure generation and balanced flow transfer across continuous-duty operating conditions. Threaded suction and discharge ports in ISO 228\/1 configuration simplify connection into service pipelines and utility circulation assemblies.\u003c\/p\u003e\n\n\u003cp\u003eFlow stability is supported through a closed impeller arrangement engineered for controlled hydraulic transfer with non-abrasive liquids. The impeller, casing, shaft, and casing cover are produced in AISI 304 stainless steel, contributing to corrosion resistance and long-term hydraulic consistency in clean water systems. The close-coupled arrangement minimizes alignment requirements between the motor and hydraulic section, while the threaded connection design simplifies maintenance and replacement procedures in confined installation environments.\u003c\/p\u003e\n\n\u003cp\u003eMechanical sealing is achieved using ceramic alumina and carbon seal faces combined with EPDM elastomer components. The pump is suitable for liquid temperatures ranging from -10°C to +90°C with maximum permissible working pressure up to 10 bar. Class F motor insulation and IP54 protection support dependable operation in industrial utility environments, and the motor construction complies with continuous-duty operation requirements. Inlet connection size is G 1 1\/4 while the outlet connection is G 1, supporting compatibility with standard utility pipework installations.\u003c\/p\u003e\n\n\u003cstrong\u003eFEATURES\u003c\/strong\u003e\n\u003cul\u003e\n\u003cli\u003eClose-coupled centrifugal pump construction reducing installation footprint\u003c\/li\u003e\n\u003cli\u003eClosed impeller hydraulic design for balanced pressure generation\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 configuration\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 near 2900 rpm\u003c\/li\u003e\n\u003cli\u003eClass F motor insulation with IP54 enclosure protection\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Calpeda","offers":[{"title":"Default Title","offer_id":50755547234551,"sku":"NMX 25\/70B","price":679.75,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/calpeda-nmx-25-70b-stainless-steel-close-coupled-centrifugal-pump-for-irrigation-with-304-ss-impeller.png?v=1778309059","url":"https:\/\/foundationpumps.com.au\/products\/calpeda-nmx-25-70b-stainless-steel-close-coupled-centrifugal-pump-for-irrigation-with-304-ss-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
