Circulation systems used in aquatic filtration installations require stable hydraulic performance together with dependable suspended solids handling capability. The Calpeda B-NMP 32/12A is engineered for these operating environments using an automatic priming hydraulic configuration combined with integrated filtration protection for clean and lightly contaminated water applications.
Powered by a three-phase 415V motor, the pump delivers flow rates up to 250 L/Min while generating a maximum head of 22 m from the first operating point after zero flow. Its 1.1 kW rated output power supports residential and commercial filtration systems requiring increased circulation pressure together with stable recirculation performance.
The 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 automatic priming arrangement improves suction recovery during intermittent operating cycles while maintaining balanced hydraulic circulation behaviour during extended filtration service.
Bronze 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.
