The self-priming centrifugal configuration is suited to drainage duties, irrigation supply systems, sump emptying, and utility water movement involving clean or slightly dirty liquids.\u003c\/p\u003e\u003cp\u003eHydraulic performance reaches flow rates up to 18 m³\/h with maximum head extending to 15.4 m, supporting balanced low-to-medium pressure transfer across civil and industrial operating conditions. The hydraulic assembly is driven through a 240V single-phase induction motor delivering 0.75 kW rated output power with rated operating current of 5.7 A while maintaining operating speed near 2900 rpm.\u003c\/p\u003e\u003cp\u003eStable hydraulic circulation is supported through an open cast iron impeller arrangement capable of handling suspended solids up to 10 mm without restricting liquid passage. The hydraulic design assists uninterrupted flow movement during intermittent-duty operation while the self-priming system restores suction capability automatically after shutdown or temporary dry suction conditions.\u003c\/p\u003e\u003cp\u003eCast iron manufacture is utilized across the casing, lantern bracket, cylindrical suction section, and impeller assembly to provide structural durability during prolonged operating service. Carbon ceramic mechanical seal faces with NBR elastomer support components assist shaft sealing reliability, while the close-coupled motor arrangement incorporates capacitor-start operation, built-in thermal overload protection, class F insulation, and IP54 enclosure protection. Operating capability supports liquid temperatures from -10°C to 90°C with maximum permissible working pressure up to 6 bar.\u003c\/p\u003e\u003cstrong\u003eFEATURES\u003c\/strong\u003e\u003cul\u003e\n\u003cli\u003eSelf-priming centrifugal arrangement supporting automatic suction restoration\u003c\/li\u003e\n\u003cli\u003eOpen cast iron impeller assisting transfer of liquids containing suspended solids\u003c\/li\u003e\n\u003cli\u003eHydraulic configuration capable of handling particles up to 10 mm in size\u003c\/li\u003e\n\u003cli\u003eIntegrated anti-siphon functionality reducing reverse flow during shutdown periods\u003c\/li\u003e\n\u003cli\u003eClose-coupled motor and pump structure minimizing alignment requirements\u003c\/li\u003e\n\u003cli\u003eCarbon ceramic mechanical sealing system with NBR elastomer support elements\u003c\/li\u003e\n\u003cli\u003eSingle-phase capacitor-start induction motor with integrated thermal protection\u003c\/li\u003e\n\u003cli\u003eIP54 protected enclosure combined with class F motor insulation construction\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Calpeda","offers":[{"title":"Default Title","offer_id":50762858234103,"sku":"AM 40-110A","price":2025.21,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/calpeda-am-40-110a-cast-iron-self-priming-centrifugal-pump-for-irrigation-supply-with-open-impeller.png?v=1778576249","url":"https:\/\/foundationpumps.com.au\/products\/calpeda-am-40-110a-cast-iron-self-priming-centrifugal-pump-for-irrigation-supply-with-open-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
