Clean water systems operating from standard single-phase electrical supply can utilize the Calpeda NMXM 25/70A where compact centrifugal construction and stainless steel hydraulic materials are required. The pump combines a close-coupled layout with AISI 304 stainless steel wetted components, supporting reliable handling of liquids that are non-aggressive toward stainless steel materials. Its configuration is suitable for domestic circulation, irrigation support, garden water movement, utility transfer, and civil service applications requiring continuous-duty operation.
The hydraulic section develops maximum head up to 25.8 m while maintaining flow rates reaching 5.4 m³/h. Power is supplied through a 230V single-phase induction motor rated at 0.75 kW with maximum power input of 1.2 kW and operating current of 5.7 A. A two-pole motor arrangement operating near 2900 rpm contributes to balanced pressure generation and stable hydraulic transfer during varying operating demand. The suction and discharge ports use ISO 228/1 threaded connections for simplified integration into compact utility pipe systems.
Inside the hydraulic assembly, a closed impeller arrangement manages movement of clean, non-abrasive liquids with controlled circulation characteristics. Stainless steel construction is applied across the casing, shaft, impeller, and casing cover to support corrosion resistance and long-term hydraulic consistency during extended operation. The direct motor-to-pump coupling minimizes alignment requirements while helping reduce overall installation complexity compared with separately coupled assemblies.
Mechanical sealing is supported through ceramic alumina and carbon seal faces operating together with EPDM elastomer components. The pump is suitable for liquid temperatures ranging from -10°C to +90°C with maximum permissible working pressure up to 10 bar. Class F motor insulation together with IP54 enclosure protection supports dependable continuous-duty operation, while the integrated thermal protector incorporated into NMXM single-phase models provides additional operating safety. Approximate unit weight is 12 kg.
