The centrifugal hydraulic arrangement supports dependable operation where intake pipelines experience fluctuating suction conditions or temporary emptying during shutdown periods.\u003c\/p\u003e\n\n\u003cp\u003eAn open bronze impeller maintains unrestricted liquid circulation while allowing suspended solids up to 10 mm to pass through the hydraulic section without obstructing flow movement. Automatic suction restoration is achieved through the integrated self-priming system during restart following interrupted operating cycles.\u003c\/p\u003e\n\n\u003cp\u003eHydraulic performance reaches 66 m³\/h maximum flow with discharge head extending to 27.3 m, supporting large-volume transfer across higher-pressure operating systems. Power is supplied through a three-phase 400V induction motor rated at 5.5 kW output power with operating current of 6.2 A while maintaining rotational speed near 2900 rpm.\u003c\/p\u003e\n\n\u003cp\u003eBronze construction across the hydraulic casing, impeller assembly, cylindrical suction section, and lantern bracket contributes durability within demanding liquid handling environments. Carbon ceramic mechanical seal faces with NBR elastomer support materials assist shaft sealing stability, while the close-coupled motor assembly integrates IP54 enclosure protection and class F insulation. Operating temperatures extend from -10°C to 90°C with maximum permissible working pressure reaching 6 bar.\u003c\/p\u003e\n\n\u003cstrong\u003eFEATURES\u003c\/strong\u003e\n\u003cul\u003e\n\u003cli\u003e80 mm threaded suction and discharge hydraulic connection arrangement\u003c\/li\u003e\n\u003cli\u003eBronze hydraulic construction supporting demanding transfer service environments\u003c\/li\u003e\n\u003cli\u003eOpen impeller geometry allowing suspended solids passage up to 10 mm\u003c\/li\u003e\n\u003cli\u003eSelf-priming centrifugal operation assisting dependable suction restoration\u003c\/li\u003e\n\u003cli\u003eClose-coupled pump configuration reducing installation space requirements\u003c\/li\u003e\n\u003cli\u003eCarbon ceramic shaft sealing faces with NBR elastomer support elements\u003c\/li\u003e\n\u003cli\u003eThree-phase induction motor arrangement utilizing class F insulation\u003c\/li\u003e\n\u003cli\u003eIP54 enclosure protection assisting environmental operating resistance\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Calpeda","offers":[{"title":"Default Title","offer_id":50762871767287,"sku":"B-A 80-170B","price":14368.15,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/calpeda-b-a-80-170b-bronze-automatic-re-priming-centrifugal-pump-for-sump-emptying-with-open-impeller.png?v=1778579108","url":"https:\/\/foundationpumps.com.au\/products\/calpeda-b-a-80-170b-bronze-automatic-re-priming-centrifugal-pump-for-sump-emptying-with-open-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
