By utilizing high-grade AISI 316 stainless steel components throughout its fluid-contact areas, the unit ensures integrity when processing aggressive water types or industrial chemicals. Its compact, horizontal configuration makes it suitable for integration into tight machinery spaces where horizontal foot-mounting is required, providing a stable foundation for steady-state fluid movement in water treatment or temperature control applications.\u003c\/p\u003e\n\n\u003cp\u003eOperational threshold limits are defined by a Max Head 69 m alongside a Max Flow 40 L\/Min for this specific model configuration. The system draws 0.82 kW at 240v, managed by a two-pole motor design that maintains consistent speed for high-pressure delivery requirements. Performance curves verify that even under load, the hydraulics maintain stability across the operational window, supporting continuous usage cycles in professional water circulation systems.\u003c\/p\u003e\n\n\u003cp\u003eFluid dynamics are governed by a multistage arrangement that progressively increases pressure through each internal chamber. The AISI 316L stainless steel architecture of the rotating components minimizes hydraulic friction losses, promoting energy-efficient fluid acceleration from the suction port to the discharge nozzle. This internal design utilizes precision-engineered clearances to ensure minimal recirculation within the stages, which assists in maintaining high volumetric efficiency during sustained operation.\u003c\/p\u003e\n\n\u003cp\u003eHousing the assembly is a TEFC electric motor that provides protection against ambient moisture and particulates to an IP55 standard. Mechanical sealing is handled by silicon carbide surfaces paired with EPDM elastomers to manage internal pressure stresses effectively. The unit is designed for direct mounting, using standard 25 mm inlet and outlet connections that facilitate fast installation into existing rigid piping networks, requiring only standard electrical termination for system integration.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eFeatures:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eSilicon carbide mechanical seal surfaces for enhanced resistance\u003c\/li\u003e\n  \u003cli\u003eTEFC electric motor housing with IP55 environmental protection\u003c\/li\u003e\n  \u003cli\u003eAISI 316 stainless steel construction for chemical handling\u003c\/li\u003e\n  \u003cli\u003eEPDM elastomer sealing components for fluid compatibility\u003c\/li\u003e\n  \u003cli\u003eTwo-pole motor operating at approximately 2900 rpm speed\u003c\/li\u003e\n  \u003cli\u003eCertified for drinking water contact per international standards\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Lowara","offers":[{"title":"Default Title","offer_id":50806151938295,"sku":"1HM12N05M","price":1636.47,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/lowara-1hm12n05m-quiet-stainless-steel-multistage-pump-for-cooling-systems-with-closed-impeller.png?v=1779765414","url":"https:\/\/foundationpumps.com.au\/products\/lowara-1hm12n05m-quiet-stainless-steel-multistage-pump-for-cooling-systems-with-closed-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
