The Calpeda NMXM 25/70B is configured for clean water movement in compact installations where single-phase operation and stainless steel hydraulic construction are required. Its close-coupled centrifugal layout utilizes AISI 304 stainless steel components, supporting operation with liquids that are non-aggressive toward stainless steel materials. The compact design assists direct installation into domestic, civil, and utility service systems.
Hydraulic performance reaches up to 18.1 m maximum head with flow rates extending to 5.4 m³/h. The pump is driven by a 240V single-phase induction motor delivering 0.55 kW rated output power. Operating speed is approximately 2900 rpm through a two-pole motor configuration, supporting smooth pressure generation and balanced flow transfer across continuous-duty operating conditions.
Flow stability is supported through a closed impeller arrangement engineered for reliable clean liquid transfer. Threaded suction and discharge ports in ISO 228/1 configuration simplify connection into service pipelines and utility circulation assemblies, while direct motor-to-pump coupling reduces alignment requirements.
Ceramic alumina and carbon mechanical seal faces operate together with EPDM elastomer components to provide sealing reliability. The single-phase motor incorporates integrated thermal protection, class F insulation, and IP54 enclosure protection. Liquid temperature capability covers -10°C to +90°C with maximum casing pressure up to 10 bar.
