Its close-coupled centrifugal layout supports operation with liquids that are non-aggressive toward AISI 304 stainless steel materials, making the pump suitable for domestic systems, irrigation duties, garden water movement, civil circulation applications, and general utility service installations operating under continuous-duty conditions.\u003c\/p\u003e\n\n\u003cp\u003eHydraulic output reaches a maximum head of 18.1 m with flow rates extending to 5.4 m³\/h. The pump operates using a 230V single-phase induction motor rated at 0.55 kW with maximum power input of 1 kW and operating current of 4.5 A. Running speed remains approximately 2900 rpm through a two-pole motor configuration, supporting balanced hydraulic transfer and stable circulation performance across varying operating demand. ISO 228\/1 threaded hydraulic connections simplify installation into compact utility pipe systems.\u003c\/p\u003e\n\n\u003cp\u003eClean liquid movement is controlled through a closed impeller arrangement designed for smooth transfer characteristics with non-abrasive fluids. Stainless steel construction is used throughout the casing, impeller, shaft, and casing cover to support corrosion resistance and hydraulic consistency during extended operating periods. Because the motor shaft is directly connected to the hydraulic section, installation complexity and alignment requirements are reduced compared with separately coupled pump arrangements.\u003c\/p\u003e\n\n\u003cp\u003eCeramic alumina and carbon mechanical seal faces operate together with EPDM elastomer sealing components to support dependable sealing performance. The pump is suitable for liquid temperatures ranging from -10°C to +90°C with maximum permissible working pressure up to 10 bar. Motor construction includes class F insulation together with IP54 enclosure protection, while the integrated thermal protector incorporated into NMXM single-phase models provides additional operating safety. Approximate unit weight is 10.7 kg.\u003c\/p\u003e\n\n\u003cstrong\u003eFEATURES\u003c\/strong\u003e\n\u003cul\u003e\n\u003cli\u003e230V single-phase motor configuration for standard electrical supply compatibility\u003c\/li\u003e\n\u003cli\u003eDirect-coupled centrifugal layout reducing installation footprint and alignment adjustments\u003c\/li\u003e\n\u003cli\u003eClosed impeller geometry developed for smooth transfer of clean non-abrasive liquids\u003c\/li\u003e\n\u003cli\u003eAISI 304 stainless steel hydraulic components throughout the wetted section\u003c\/li\u003e\n\u003cli\u003eIntegrated thermal protector supporting additional motor operating protection\u003c\/li\u003e\n\u003cli\u003eISO 228\/1 threaded suction and discharge ports for utility pipe integration\u003c\/li\u003e\n\u003cli\u003eCeramic alumina\/carbon mechanical seal arrangement with EPDM elastomer elements\u003c\/li\u003e\n\u003cli\u003eIP54 motor enclosure with class F insulation and approximate 2900 rpm operation\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Calpeda","offers":[{"title":"Default Title","offer_id":50755547562231,"sku":"NMXM 25\/70B","price":661.98,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/calpeda-nmxm-25-70b-stainless-steel-thermal-protected-centrifugal-pump-for-domestic-use-with-304-ss-impeller.png?v=1778309323","url":"https:\/\/foundationpumps.com.au\/products\/calpeda-nmxm-25-70b-stainless-steel-thermal-protected-centrifugal-pump-for-domestic-use-with-304-ss-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
