Its configuration excels in cooling systems and liquid circulation duties where stable flow characteristics are necessary. Designed for direct installation, the pump addresses the requirements of mid-scale hydraulic loops and process water handling where space-efficient footprints and mechanical precision are essential for system integration.\u003c\/p\u003e\n\n\u003cp\u003eOperation is defined by a high-efficiency motor architecture and a multi-stage hydraulic assembly that generates significant lift. Max Head approximately 154 m and Max Flow approximately 73.3 L\/Min. The pump incorporates an AISI 304 stainless steel fluid path to maintain water integrity. Electrical power input is 2.22 kW \/ 240v, ensuring balanced consumption for its performance output, while 25 mm inlet and 25 mm outlet connections facilitate standard plumbing integration.\u003c\/p\u003e\n\n\u003cp\u003eThe internal architecture utilizes a sequence of stainless steel components optimized for hydraulic stability. By employing a multi-stage configuration, the pump manages fluid energy through successive stages, effectively elevating pressure without the erratic flow fluctuations seen in single-stage designs. This series emphasizes laminar flow management and reduced internal turbulence, contributing to long-term operational consistency during continuous duty cycles.\u003c\/p\u003e\n\n\u003cp\u003eConstructed with a close-coupled arrangement, the motor and hydraulic end are unified to ensure shaft alignment and structural rigidity. The exterior features a TEFC motor enclosure rated to IP 55, providing protection against external debris and moisture. Safety features include integrated thermal overload protection designed to safeguard the motor during intense demand, while the stainless steel construction offers resistance against common chemical and thermal degradation within diverse water handling circuits.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eFeatures:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eTEFC squirrel-cage motor configuration with F-class thermal insulation\u003c\/li\u003e\n  \u003cli\u003ePrecision-engineered AISI 304 stainless steel housing and hydraulic components\u003c\/li\u003e\n  \u003cli\u003eIP55 motor protection index for operation in challenging environments\u003c\/li\u003e\n  \u003cli\u003eBalanced mechanical seal interface compliant with EN 12756 standards\u003c\/li\u003e\n  \u003cli\u003eIntegrated automatic reset overload protection for system safety\u003c\/li\u003e\n  \u003cli\u003eOptimized shaft alignment via close-coupled motor flange mounting\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Lowara","offers":[{"title":"Default Title","offer_id":50799701688567,"sku":"3HM21S22M","price":3060.81,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/lowara-3hm21s22m-compact-stainless-steel-quiet-running-multistage-pump-for-process-water-with-closed-impeller.png?v=1779519772","url":"https:\/\/foundationpumps.com.au\/products\/lowara-3hm21s22m-compact-stainless-steel-quiet-running-multistage-pump-for-process-water-with-closed-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
