Where utility pipe systems require balanced flow and moderate discharge pressure, the Calpeda NMXLM 25/120B supports clean liquid handling through a compact centrifugal arrangement suited to continuous-duty operation. Its AISI 316L stainless steel hydraulic section allows operation with liquids that are non-aggressive toward stainless steel materials while supporting installation within confined mechanical service environments.
Hydraulic capability reaches 27.8 m maximum head with flow rates extending to 9.6 m³/h. A single-phase 230V induction motor rated at 1.1 kW supplies power to the hydraulic assembly while operating at 7 A under rated conditions, with maximum input power reaching 1.5 kW. The two-pole motor configuration maintains operating speed near 2900 rpm for stable pressure generation and consistent liquid movement.
Flow transfer is managed through a closed impeller arrangement developed for clean, non-abrasive liquids. Hydraulic movement remains controlled across varying operating demand while threaded ISO 228/1 suction and discharge ports simplify integration into compact utility circulation layouts without additional coupling assemblies.
Ceramic alumina and carbon mechanical seal faces operate together with EPDM elastomer elements to support sealing stability during prolonged service operation. The close-coupled structure reduces alignment complexity between motor and hydraulic section, while class F insulation and IP54 enclosure protection support continuous-duty motor operation. Operating capability covers liquid temperatures from -10°C to +90°C with maximum permissible working pressure up to 10 bar.
