Moderate-pressure clean liquid circulation duties can integrate the Calpeda NMXL 25/70A where corrosion-resistant hydraulic construction and compact installation are important operating requirements. AISI 316L stainless steel is used throughout the wetted hydraulic section, supporting operation with liquids compatible with stainless steel materials while maintaining reduced installation complexity through a direct-coupled centrifugal arrangement.
Maximum hydraulic head reaches 25.8 m with flow rates extending to 5.4 m³/h. Power transmission is provided through a three-phase 400V induction motor rated at 0.75 kW with operating current of 2.2 A. Operating speed remains approximately 2900 rpm through a two-pole motor configuration supporting balanced pressure development during continuous operation.
Movement of clean, non-abrasive liquids is managed through a closed impeller configuration engineered for controlled hydraulic transfer characteristics. ISO 228/1 threaded hydraulic ports simplify integration into compact circulation assemblies, while ceramic alumina and carbon mechanical seal faces combined with EPDM elastomer components support sealing stability. The motor assembly incorporates IP54 enclosure protection together with class F insulation for continuous-duty operating environments.
