Cooling circuits, utility transfer lines, and clean water circulation systems can utilize the Calpeda NMX 25/90A where compact centrifugal construction and stainless steel hydraulic components are required. The pump uses a close-coupled configuration that reduces installation footprint while supporting operation with clean liquids that are non-aggressive toward AISI 304 stainless steel materials. Its layout is suited to civil, industrial, irrigation, and general service applications requiring stable continuous circulation.
The hydraulic section develops maximum head up to 28.2 m with flow rates reaching 6.6 m³/h. Power is supplied through a three-phase 400V induction motor rated at 1.1 kW with operating current of 2.6 A. A two-pole motor arrangement operating near 2900 rpm supports balanced hydraulic transfer and controlled pressure development across continuous-duty operating conditions. Threaded ISO 228/1 suction and discharge ports simplify integration into circulation pipelines and utility water systems.
Liquid movement is managed through a closed impeller arrangement intended for smooth transfer of clean, non-abrasive fluids. Stainless steel construction is used throughout the impeller, shaft, casing, and casing cover, contributing to corrosion resistance and hydraulic consistency during extended operation. The direct-coupled motor and hydraulic assembly minimizes alignment complexity while maintaining simplified servicing access in compact installation environments.
Ceramic alumina and carbon mechanical seal faces operate together with EPDM elastomer components to support reliable sealing performance. Operating capability includes liquid temperatures from -10°C to +90°C with maximum permissible working pressure up to 10 bar. The motor assembly incorporates class F insulation with IP54 enclosure protection for continuous-duty operation in industrial and utility environments. Inlet connection size is G 1 1/4 and outlet connection size is G 1.
