The Calpeda B-NMPM 32\/12A is engineered for these operating environments using an auto-priming hydraulic configuration combined with integrated filtration protection for clean and lightly contaminated water applications.\u003c\/p\u003e\u003cp\u003ePowered by a single-phase 240V motor, the pump delivers flow rates up to 250 L\/Min while generating a maximum head of 21.5 m from the first operating point after zero flow. Its 1.1 kW rated output power configuration supports residential and light commercial filtration systems requiring increased circulation pressure together with stable recirculation performance.\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 in separating suspended particles before liquid enters the impeller chamber. Its auto-priming arrangement improves suction recovery during intermittent operating cycles while maintaining balanced hydraulic circulation behaviour during extended filtration service.\u003c\/p\u003e\u003cp\u003eBronze construction throughout the pump casing and lantern bracket improves corrosion resistance in chemically treated aquatic environments and continuous moisture exposure conditions. The close-coupled motor configuration simplifies installation requirements, while the Carbon\/Ceramic\/FPM mechanical seal, IPX4 enclosure protection, and Class F insulation system contribute to reliable long-term continuous-duty operation.\u003c\/p\u003e\u003cstrong\u003eFEATURES\u003c\/strong\u003e\u003cul\u003e\n\u003cli\u003eAuto-priming hydraulic configuration for continuous pool filtration duty\u003c\/li\u003e\n\u003cli\u003eIntegrated removable basket strainer with Ø3 mm perforated filtration section\u003c\/li\u003e\n\u003cli\u003eChrome-plated brass impeller engineered for balanced hydraulic circulation\u003c\/li\u003e\n\u003cli\u003eBronze casing and lantern bracket construction for corrosion-resistant operation\u003c\/li\u003e\n\u003cli\u003eCompact close-coupled motor arrangement minimizing installation complexity\u003c\/li\u003e\n\u003cli\u003eCarbon\/Ceramic\/FPM mechanical seal configuration for prolonged filtration service\u003c\/li\u003e\n\u003cli\u003eTwo-pole 2900 rpm induction motor supporting stable recirculation operation\u003c\/li\u003e\n\u003cli\u003eClass F insulated motor with IPX4 enclosure protection for aquatic environments\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Calpeda","offers":[{"title":"Default Title","offer_id":50773055668471,"sku":"B-NMPM 32\/12A","price":7615.96,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/calpeda-b-nmpm-32-12a-bronze-auto-priming-centrifugal-pump-for-pool-filtration-with-brass-impeller.png?v=1778647837","url":"https:\/\/foundationpumps.com.au\/products\/calpeda-b-nmpm-32-12a-bronze-auto-priming-centrifugal-pump-for-pool-filtration-with-brass-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
