Higher discharge head requirements within compact clean liquid systems can be supported by the Calpeda NMXLM 25/120A through its stainless steel close-coupled centrifugal construction. The hydraulic assembly uses AISI 316L stainless steel materials suitable for liquids compatible with stainless steel components while maintaining corrosion-resistant operating characteristics during continuous-duty service.
Maximum hydraulic head reaches 35.3 m with flow rates extending to 9.6 m³/h. Power transmission is supplied through a single-phase 230V induction motor rated at 1.5 kW with operating current of 9.2 A and maximum input power of 2 kW. Stable pressure-focused hydraulic behavior is supported through a two-pole motor configuration operating near 2900 rpm during prolonged operation.
Movement of clean, non-abrasive liquids is controlled through a closed impeller arrangement developed for balanced hydraulic transfer behavior. Threaded ISO 228/1 suction and discharge ports simplify integration into utility circulation systems while maintaining compact installation characteristics within restricted service environments.
Mechanical sealing incorporates ceramic alumina and carbon seal faces combined with EPDM elastomer support elements. The close-coupled structure minimizes alignment requirements between the motor and hydraulic section, while the motor enclosure integrates class F insulation together with IP54 protection. Liquid temperature capability ranges from -10°C to +90°C with maximum permissible working pressure up to 10 bar.
