Maintaining steady circulation in commercial and residential pool systems requires dependable hydraulic stability, particularly where suspended particles and continuous recirculation loads are present. The Calpeda B-NMP 32/12D is engineered for these operating conditions, combining self-priming capability with an integrated filtration chamber to support efficient aquatic water management and filtration circulation duties.
Its three-phase 415V motor configuration develops flow rates up to 250 L/Min while producing a maximum head of 18 m from the first performance point beyond zero flow. The 0.75 kW rated output power provides balanced hydraulic performance for filtration loops, pool recirculation systems, and water renewal installations where stable operating pressure and consistent circulation behaviour are essential.
The hydraulic assembly incorporates a chrome-plated brass impeller together with a built-in basket strainer featuring Ø3 mm perforations for debris separation before entering the impeller chamber. This arrangement assists in maintaining uninterrupted circulation efficiency while supporting smooth suction recovery during intermittent priming cycles and extended filtration operation.
Bronze hydraulic components provide enhanced durability in chemically treated water environments and help resist corrosion during long-term service exposure. A compact close-coupled installation simplifies pipeline integration, while the Carbon/Ceramic/FPM mechanical seal, Class F insulated motor, and IPX4 enclosure protection deliver dependable continuous-duty operation.
