Utility service installations and auxiliary circulation systems can benefit from its combination of unrestricted liquid passage and increased transfer capacity.\u003c\/p\u003e\n\n\u003cp\u003eFlow handling capability reaches 15 m³\/h with discharge head extending to 15.6 m, supporting balanced liquid circulation across medium-capacity hydraulic operating systems. The pump is driven through a 230V single-phase induction motor utilizing 0.78 kW maximum input power with operating current of 4.5 A while maintaining rotational speed near 2900 rpm.\u003c\/p\u003e\n\n\u003cp\u003eInside the hydraulic section, suspended particles up to 4 mm can pass through the open impeller arrangement without excessive restriction to liquid movement. The centrifugal flow path assists dependable circulation characteristics while handling moderately dirty liquids under varying operating loads.\u003c\/p\u003e\n\n\u003cp\u003eCast iron manufacture across the casing and lantern bracket assembly contributes structural durability during operating duty. Carbon ceramic mechanical seal faces combined with NBR elastomer support components manage shaft sealing operation, while the motor assembly incorporates capacitor-start operation, built-in thermal protection, class F insulation, and IP54 enclosure protection. Operating capability supports liquid temperatures ranging from -10°C to 90°C with working pressure capability up to 6 bar.\u003c\/p\u003e\n\n\u003cstrong\u003eFEATURES\u003c\/strong\u003e\n\u003cul\u003e\n\u003cli\u003eOpen centrifugal impeller supporting unrestricted medium-volume liquid circulation\u003c\/li\u003e\n\u003cli\u003eHydraulic passage suitable for suspended solids handling up to 4 mm\u003c\/li\u003e\n\u003cli\u003eClose-coupled motor and pump structure minimizing installation requirements\u003c\/li\u003e\n\u003cli\u003eSingle-phase induction motor configured for 230V operating supply conditions\u003c\/li\u003e\n\u003cli\u003eCapacitor-start motor arrangement with integrated thermal protection\u003c\/li\u003e\n\u003cli\u003eCarbon ceramic sealing faces with NBR elastomer support materials\u003c\/li\u003e\n\u003cli\u003eIP54 enclosure protection assisting environmental operating durability\u003c\/li\u003e\n\u003cli\u003eClass F insulated motor construction supporting stable thermal operation\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Calpeda","offers":[{"title":"Default Title","offer_id":50773059567863,"sku":"CM 4\/1","price":1035.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/calpeda-cm-4-1-cast-iron-close-coupled-centrifugal-pump-for-process-water-circulation-with-open-impeller.png?v=1778649367","url":"https:\/\/foundationpumps.com.au\/products\/calpeda-cm-4-1-cast-iron-close-coupled-centrifugal-pump-for-process-water-circulation-with-open-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
