The pump combines a close-coupled layout with AISI 304 stainless steel wetted components, supporting reliable handling of liquids that are non-aggressive toward stainless steel materials. Its configuration is suitable for domestic circulation, irrigation support, garden water movement, utility transfer, and civil service applications requiring continuous-duty operation.\u003c\/p\u003e\n\n\u003cp\u003eThe hydraulic section develops maximum head up to 25.8 m while maintaining flow rates reaching 5.4 m³\/h. Power is supplied through a 230V single-phase induction motor rated at 0.75 kW with maximum power input of 1.2 kW and operating current of 5.7 A. A two-pole motor arrangement operating near 2900 rpm contributes to balanced pressure generation and stable hydraulic transfer during varying operating demand. The suction and discharge ports use ISO 228\/1 threaded connections for simplified integration into compact utility pipe systems.\u003c\/p\u003e\n\n\u003cp\u003eInside the hydraulic assembly, a closed impeller arrangement manages movement of clean, non-abrasive liquids with controlled circulation characteristics. Stainless steel construction is applied across the casing, shaft, impeller, and casing cover to support corrosion resistance and long-term hydraulic consistency during extended operation. The direct motor-to-pump coupling minimizes alignment requirements while helping reduce overall installation complexity compared with separately coupled assemblies.\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 with maximum permissible working pressure up to 10 bar. Class F motor insulation together with IP54 enclosure protection supports dependable continuous-duty operation, while the integrated thermal protector incorporated into NMXM single-phase models provides additional operating safety. Approximate unit weight is 12 kg.\u003c\/p\u003e\n\n\u003cstrong\u003eFEATURES\u003c\/strong\u003e\n\u003cul\u003e\n\u003cli\u003eSingle-phase 230V induction motor for operation from standard electrical supply\u003c\/li\u003e\n\u003cli\u003eClose-coupled centrifugal arrangement minimizing installation space requirements\u003c\/li\u003e\n\u003cli\u003eClosed impeller hydraulic geometry supporting stable clean liquid circulation\u003c\/li\u003e\n\u003cli\u003eAISI 304 stainless steel casing, impeller, shaft, and casing cover construction\u003c\/li\u003e\n\u003cli\u003eIntegrated thermal protection system for additional motor operating safety\u003c\/li\u003e\n\u003cli\u003eThreaded ISO 228\/1 suction and discharge ports simplifying pipe integration\u003c\/li\u003e\n\u003cli\u003eCeramic alumina\/carbon sealing surfaces combined with EPDM elastomer elements\u003c\/li\u003e\n\u003cli\u003eTwo-pole motor operating near 2900 rpm with IP54 enclosure protection\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Calpeda","offers":[{"title":"Default Title","offer_id":50755547594999,"sku":"NMXM 25\/70A","price":689.1,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/calpeda-nmxm-25-70a-stainless-steel-single-phase-centrifugal-pump-for-water-circulation-with-304-ss-impeller.png?v=1778309341","url":"https:\/\/foundationpumps.com.au\/products\/calpeda-nmxm-25-70a-stainless-steel-single-phase-centrifugal-pump-for-water-circulation-with-304-ss-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
