The pump operates in a close-coupled configuration that reduces overall installation footprint while supporting continuous-duty operation with liquids that are non-aggressive toward AISI 304 stainless steel materials. Its hydraulic layout is suitable for industrial utility circulation, service water movement, irrigation support, and process transfer applications.\u003c\/p\u003e\n\n\u003cp\u003eThe hydraulic section develops maximum head up to 37.1 m while supporting flow rates reaching 15 m³\/h. Power is supplied through a three-phase 400V induction motor rated at 2.2 kW with operating current of 5.3 A. A two-pole motor arrangement operating near 2900 rpm contributes to controlled pressure generation and stable hydraulic transfer during prolonged operating cycles. The suction and discharge ports are threaded according to ISO 228\/1 standards for simplified integration into utility and circulation pipe systems.\u003c\/p\u003e\n\n\u003cp\u003eInside the hydraulic assembly, a closed impeller arrangement manages movement of clean, non-abrasive liquids with balanced flow characteristics and stable circulation behavior. The casing, shaft, impeller, and casing cover are manufactured in AISI 304 stainless steel to support corrosion resistance and long-term hydraulic consistency during extended service operation. Direct coupling between the motor and hydraulic section minimizes alignment adjustments while simplifying installation within compact mechanical environments.\u003c\/p\u003e\n\n\u003cp\u003eMechanical sealing is supported through ceramic alumina and carbon seal faces operating together with EPDM elastomer components. The pump is suitable for liquid temperatures ranging from -10°C to +90°C and supports maximum permissible working pressure up to 10 bar. Class F motor insulation together with IP54 enclosure protection supports dependable operation in industrial and utility circulation conditions. The inlet connection size is G 1 1\/2 while the outlet connection size is G 1.\u003c\/p\u003e\n\n\u003cstrong\u003eFEATURES\u003c\/strong\u003e\n\u003cul\u003e\n\u003cli\u003eHigh-head hydraulic configuration supporting pressure-focused circulation duties\u003c\/li\u003e\n\u003cli\u003e15 m³\/h maximum flow capacity combined with 37.1 m discharge head performance\u003c\/li\u003e\n\u003cli\u003eCompact close-coupled motor arrangement simplifying installation in confined layouts\u003c\/li\u003e\n\u003cli\u003eClosed impeller geometry developed for controlled transfer of clean liquids\u003c\/li\u003e\n\u003cli\u003eHydraulic components manufactured entirely from AISI 304 stainless steel\u003c\/li\u003e\n\u003cli\u003eThreaded ISO 228\/1 suction and discharge ports for utility pipeline compatibility\u003c\/li\u003e\n\u003cli\u003eCeramic alumina\/carbon seal faces with EPDM elastomer sealing support elements\u003c\/li\u003e\n\u003cli\u003eTwo-pole induction motor with class F insulation and IP54 enclosure protection\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Calpeda","offers":[{"title":"Default Title","offer_id":50755547529463,"sku":"NMX 25\/200A","price":1115.46,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/calpeda-nmx-25-200a-stainless-steel-high-head-centrifugal-pump-for-liquid-transfer-with-304-ss-impeller.png?v=1778310360","url":"https:\/\/foundationpumps.com.au\/products\/calpeda-nmx-25-200a-stainless-steel-high-head-centrifugal-pump-for-liquid-transfer-with-304-ss-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
