Unrestricted fluid passage supports auxiliary circulation equipment and compact transfer installations handling emulsions and similar liquids.\u003c\/p\u003e\u003cp\u003eHydraulic performance extends to 6.6 m³\/h maximum flow with head capability reaching 18 m, supporting moderate-pressure liquid movement across medium-capacity operating networks. The hydraulic assembly operates through a 240V single-phase induction motor utilizing 0.45 kW rated output power with operating current of 3.6 A and rotational speed near 2900 rpm.\u003c\/p\u003e\u003cp\u003eThe open impeller allows suspended particles up to 4 mm to pass through the hydraulic section without obstructing fluid movement. Centrifugal flow characteristics assist stable liquid handling behaviour when operating with moderately contaminated fluids under varying demand.\u003c\/p\u003e\u003cp\u003eStructural durability is supported through cast iron manufacture across the hydraulic body and lantern bracket assembly. Carbon ceramic mechanical seal faces operate with NBR elastomer support materials for shaft sealing, while the motor integrates capacitor-start operation, thermal overload protection, class F insulation, and IP54 enclosure protection. Liquid temperature handling ranges 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\u003eCast iron hydraulic casing supporting long-term operating durability\u003c\/li\u003e\n\u003cli\u003eOpen impeller configuration suitable for suspended solids handling up to 4 mm\u003c\/li\u003e\n\u003cli\u003eCompact centrifugal structure assisting installation within limited space areas\u003c\/li\u003e\n\u003cli\u003eSingle-phase 240V induction motor operating at approximately 2900 rpm\u003c\/li\u003e\n\u003cli\u003eIntegrated capacitor-start motor arrangement with thermal protection system\u003c\/li\u003e\n\u003cli\u003eCarbon ceramic sealing faces with NBR elastomer support components\u003c\/li\u003e\n\u003cli\u003eIP54 enclosure protection assisting operation within utility environments\u003c\/li\u003e\n\u003cli\u003eClass F insulated motor configuration supporting controlled thermal behaviour\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Calpeda","offers":[{"title":"Default Title","offer_id":50773059502327,"sku":"CM 22\/1","price":917.7,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/calpeda-cm-22-1-cast-iron-single-phase-centrifugal-pump-for-moderately-dirty-liquids-with-open-impeller.png?v=1778649332","url":"https:\/\/foundationpumps.com.au\/products\/calpeda-cm-22-1-cast-iron-single-phase-centrifugal-pump-for-moderately-dirty-liquids-with-open-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
