The Calpeda B-NMP 50\/12H is engineered for these demanding duties using an integrated priming centrifugal hydraulic configuration combined with internal debris filtration for clean and slightly contaminated water applications.\u003c\/p\u003e\u003cp\u003eDriven by a three-phase 415V motor, the pump delivers flow rates up to 900 L\/Min while generating a maximum head of 9 m from the first operating point after zero flow. The 1.1 kW rated output power is suited to large-capacity pool circulation systems, filtration loops, and aquatic recirculation installations where high-flow hydraulic transfer is prioritized over elevated pressure requirements.\u003c\/p\u003e\u003cp\u003eThe hydraulic section incorporates a chrome-plated brass impeller together with a removable basket strainer featuring Ø3 mm perforations to assist with suspended solids separation before liquid enters the impeller chamber. Its integrated priming arrangement supports smooth suction recovery performance and stable hydraulic circulation during extended filtration and recirculation duty cycles.\u003c\/p\u003e\u003cp\u003eBronze construction throughout the pump casing and lantern bracket improves resistance to corrosion in chemically treated aquatic environments and continuous moisture exposure conditions. The close-coupled motor arrangement simplifies installation requirements, while the Carbon\/Ceramic\/FPM mechanical seal, IPX4 motor protection, and Class F insulation system contribute to dependable long-term service operation.\u003c\/p\u003e\u003cstrong\u003eFEATURES\u003c\/strong\u003e\u003cul\u003e\n\u003cli\u003eIntegrated priming centrifugal hydraulic system designed for high-flow recirculation duty\u003c\/li\u003e\n\u003cli\u003eInternal removable basket strainer with Ø3 mm perforated filtration section\u003c\/li\u003e\n\u003cli\u003eChrome-plated brass impeller supporting large-volume hydraulic circulation\u003c\/li\u003e\n\u003cli\u003eBronze casing and lantern bracket construction for corrosion-resistant operation\u003c\/li\u003e\n\u003cli\u003eClose-coupled motor assembly reducing installation footprint and alignment complexity\u003c\/li\u003e\n\u003cli\u003eCarbon\/Ceramic\/FPM mechanical seal arrangement for continuous filtration service\u003c\/li\u003e\n\u003cli\u003eTwo-pole 2900 rpm induction motor engineered for stable recirculation operation\u003c\/li\u003e\n\u003cli\u003eClass F insulated motor with IPX4 enclosure protection for aquatic installations\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Calpeda","offers":[{"title":"Default Title","offer_id":50772970340599,"sku":"B-NMP 50\/12H","price":8063.22,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/calpeda-b-nmp-50-12h-bronze-integrated-priming-centrifugal-pump-for-large-pool-filtration-with-brass-impeller.png?v=1778644788","url":"https:\/\/foundationpumps.com.au\/products\/calpeda-b-nmp-50-12h-bronze-integrated-priming-centrifugal-pump-for-large-pool-filtration-with-brass-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
