The pump supports clean and slightly dirty liquids while maintaining automatic suction restoration after pipeline draining.\u003c\/p\u003e\u003cp\u003eHydraulic capacity reaches 30 m³\/h maximum flow with discharge head extending to 15.5 m, supporting efficient liquid movement across medium-pressure utility applications. The 240V single-phase motor delivers 1.1 kW rated output power and 7.4 A rated current, supporting stable 2900 rpm operation for continuous transfer requirements.\u003c\/p\u003e\u003cp\u003eCirculation is managed through an open cast iron impeller capable of handling suspended solids up to 10 mm without excessive internal restriction. During restart, the self-priming hydraulic arrangement automatically restores suction performance, mitigating operational delays caused by temporary air entry within the intake piping.\u003c\/p\u003e\u003cp\u003eStructural durability is supported by cast iron casing, lantern bracket, impeller, and cylindrical suction body components. The motor assembly features built-in thermal overload protection, IP54 enclosure rating, and class F insulation, while carbon ceramic mechanical seal faces with NBR elastomers support shaft sealing stability. Allowable liquid temperatures range from -10°C to 90°C with working pressure capability up to 6 bar.\u003c\/p\u003e\u003cstrong\u003eFEATURES\u003c\/strong\u003e\u003cul\u003e\n\u003cli\u003eIntegrated self-priming system assisting automatic suction recovery operation\u003c\/li\u003e\n\u003cli\u003eOpen cast iron impeller supporting passage of suspended solids up to 10 mm\u003c\/li\u003e\n\u003cli\u003e50 mm threaded inlet and outlet hydraulic connections\u003c\/li\u003e\n\u003cli\u003eAnti-siphon functionality helping retain prime between working cycles\u003c\/li\u003e\n\u003cli\u003eClose-coupled centrifugal structure simplifying installation layout\u003c\/li\u003e\n\u003cli\u003eCarbon ceramic shaft sealing arrangement with NBR elastomer components\u003c\/li\u003e\n\u003cli\u003eSingle-phase induction motor with built-in thermal overload protection system\u003c\/li\u003e\n\u003cli\u003eClass F insulated motor enclosure with IP54 environmental protection rating\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Calpeda","offers":[{"title":"Default Title","offer_id":50762858365175,"sku":"AM 50-125B","price":2756.71,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/calpeda-am-50-125b-cast-iron-thermal-protected-centrifugal-pump-for-industrial-washing-with-open-impeller.png?v=1778576504","url":"https:\/\/foundationpumps.com.au\/products\/calpeda-am-50-125b-cast-iron-thermal-protected-centrifugal-pump-for-industrial-washing-with-open-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
