Large-scale aquatic filtration systems require dependable hydraulic circulation together with efficient suspended solids handling during continuous-duty operation. The Calpeda B-NMP 65/12C is engineered for these demanding environments using an integrated priming centrifugal hydraulic configuration combined with internal filtration protection for clean and lightly contaminated water recirculation service.
Operating with a three-phase 400V motor configuration, the pump develops flow rates up to 2000 L/Min while generating a maximum head of 21.4 m from the first operating point after zero flow. Its 5.5 kW motor output supports high-capacity aquatic filtration installations, industrial recirculation systems, and large-volume pool water movement applications requiring elevated hydraulic performance and stable operating pressure.
The hydraulic assembly 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 integrated priming arrangement improves suction recovery capability during intermittent circulation cycles while maintaining smooth hydraulic transfer performance across prolonged filtration operation.
Bronze construction throughout the pump casing and lantern bracket improves corrosion resistance in chemically treated water environments and continuous aquatic exposure conditions. The compact close-coupled configuration reduces installation complexity, while the Carbon/Ceramic/FPM mechanical seal, IPX4 enclosure protection, and Class F insulation system contribute to dependable long-term continuous-duty operation.
