Large residential and commercial pool filtration systems can utilize the Calpeda NMPM 50/12H where stable recirculation and dependable self-priming behaviour are required during daily operating cycles. The pump is intended for clean or slightly dirty water service and suits installations where suspended debris may be present within the filtration circuit.
Water circulation capacity reaches up to 750 L/min with maximum head extending to 16.5 m depending on hydraulic resistance across the system. Operation is supplied through a 230V single-phase induction motor rated at 2.5 kW input power, maintaining rotational speed close to 2900 rpm for continuous filtration duty.
The hydraulic section incorporates a chrome-plated brass impeller paired with a self-priming centrifugal arrangement capable of suction lift operation up to 7 m. A built-in basket strainer featuring 3 mm perforations assists retention of larger suspended particles before entering the impeller chamber, helping maintain smooth circulation through the filtration line.
Cataphoresis-coated cast iron is utilized throughout the casing and lantern bracket assembly to improve durability in wet operating environments. Mechanical sealing is achieved through carbon ceramic seal faces with FPM elastomer components, while the motor assembly integrates capacitor-start operation, thermal protection, class F insulation, and IPX4 enclosure protection. Maximum water temperature is rated up to 60°C with allowable working pressure up to 6 bar.
