Basin emptying, irrigation circulation, and industrial utility service can all benefit from its ability to automatically recover suction even when the intake line has emptied during shutdown.\u003c\/p\u003e\u003cp\u003eOperating performance reaches 18 m³\/h maximum flow with discharge head up to 12.9 m, creating balanced hydraulic delivery for medium-capacity transfer requirements. The three-phase 415V induction motor delivers 0.55 kW rated output power while operating at approximately 2900 rpm with rated current of 1.6 A.\u003c\/p\u003e\u003cp\u003eSuspended solids up to 10 mm can pass through the open cast iron impeller arrangement without compromising stable hydraulic circulation. Integrated self-priming capability enables rapid suction recovery during restart conditions, limiting manual intervention across applications where liquid levels vary.\u003c\/p\u003e\u003cp\u003eMechanical rigidity is maintained through cast iron casing, cylindrical suction section, impeller assembly, and lantern bracket components. Shaft sealing is managed by carbon ceramic seal faces combined with NBR elastomer support materials, while the motor assembly features class F insulation and IP54 enclosure protection. Liquid temperature ranges from -10°C to 90°C with permissible working pressure up to 6 bar.\u003c\/p\u003e\u003cstrong\u003eFEATURES\u003c\/strong\u003e\u003cul\u003e\n\u003cli\u003eSelf-priming centrifugal configuration supporting automatic suction recovery\u003c\/li\u003e\n\u003cli\u003eOpen cast iron impeller handling suspended solids up to 10 mm\u003c\/li\u003e\n\u003cli\u003e40 mm threaded hydraulic inlet and outlet connections\u003c\/li\u003e\n\u003cli\u003eClose-coupled structural layout assisting motor installation alignment\u003c\/li\u003e\n\u003cli\u003eCarbon ceramic sealing system supports long-term shaft sealing stability\u003c\/li\u003e\n\u003cli\u003eThree-phase induction motor configuration assists continuous industrial operating duty\u003c\/li\u003e\n\u003cli\u003eIP54 motor enclosure protection reduces environmental exposure during operation\u003c\/li\u003e\n\u003cli\u003eCast iron structural components maintain rigidity across prolonged service cycles\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Calpeda","offers":[{"title":"Default Title","offer_id":50762858266871,"sku":"A 40-110B","price":1814.12,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/calpeda-a-40-110b-cast-iron-close-coupled-centrifugal-pump-for-sump-drainage-with-open-impeller.png?v=1778576279","url":"https:\/\/foundationpumps.com.au\/products\/calpeda-a-40-110b-cast-iron-close-coupled-centrifugal-pump-for-sump-drainage-with-open-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
