For swimming pool installations requiring dependable water recirculation together with automatic suction recovery, the Calpeda NMPM 50/12G provides self-priming centrifugal operation suited to filtration service. The hydraulic arrangement supports handling of clean or lightly contaminated water commonly encountered in continuous circulation systems.
Maximum flow handling reaches 750 L/min while discharge head extends to 14 m across the operating range. The pump operates through a 230V single-phase motor utilizing 1.9 kW input power and running at approximately 2900 rpm to maintain balanced filtration and recirculation performance.
Water movement is maintained through a chrome-plated brass impeller integrated within the NMPM 50/12 hydraulic assembly. The self-priming configuration supports suction lift capability up to 7 m, while the internal strainer basket incorporates 3 mm perforations to help prevent larger suspended debris from entering the hydraulic section during operation.
The casing and lantern bracket are manufactured from cataphoresis-coated cast iron for improved resistance in demanding wet-service environments. Shaft sealing is managed through carbon ceramic mechanical seal faces combined with FPM elastomer materials, while the motor assembly incorporates capacitor-start operation, built-in thermal protection, class F insulation, and IPX4 enclosure protection. Operating capability supports water temperatures up to 60°C with maximum permissible working pressure up to 6 bar.
