Where utility systems require increased discharge head together with corrosion-resistant hydraulic construction, the Calpeda NMXL 25/120A supports clean liquid circulation through a compact centrifugal arrangement. AISI 316L stainless steel is used throughout the wetted hydraulic section, allowing operation with liquids compatible with stainless steel materials while maintaining suitability for continuous-duty service conditions.
Maximum hydraulic head reaches 35.3 m with flow rates extending to 9.6 m³/h. The hydraulic assembly operates through a three-phase 400V induction motor rated at 1.5 kW with operating current of 4.3 A. A two-pole motor configuration rotating near 2900 rpm contributes to stable pressure-oriented hydraulic performance during prolonged operating cycles.
Hydraulic transfer is managed through a closed impeller arrangement designed for controlled movement of clean, non-abrasive liquids. ISO 228/1 threaded suction and discharge ports simplify integration into compact circulation systems without additional coupling assemblies. Mechanical sealing incorporates ceramic alumina and carbon seal faces combined with EPDM elastomer components, while the motor assembly integrates class F insulation and IP54 enclosure protection.
