Utility water movement and clean liquid circulation systems can integrate the Calpeda NMX 25/70A where compact centrifugal construction and corrosion-resistant hydraulic materials are required. The pump uses a close-coupled design 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 stable continuous circulation.
Maximum hydraulic head reaches 25.8 m with flow rates extending to 5.4 m³/h. Power transmission is provided through a three-phase 415V induction motor delivering 0.75 kW rated output power 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.
Clean, non-abrasive liquid transfer is controlled through a closed impeller configuration engineered for stable hydraulic movement. ISO 228/1 threaded suction and discharge ports support simplified installation within circulation pipe systems without additional coupling assemblies, while the compact direct-coupled arrangement reduces overall installation dimensions.
Mechanical sealing incorporates ceramic alumina and carbon seal faces combined with EPDM elastomer support components. The motor assembly integrates class F insulation together with IP54 enclosure protection, while operating capability includes liquid temperatures from -10°C to +90°C and maximum permissible working pressure up to 10 bar.
