The Calpeda NMXM 25/120C is intended for clean water circulation systems requiring increased flow capacity from a compact single-phase centrifugal pump. Its hydraulic section is manufactured in AISI 304 stainless steel for operation with liquids that are non-aggressive toward stainless steel materials, making the pump suitable for domestic, civil, irrigation, garden, and utility service applications where corrosion-resistant construction is important.
Maximum flow reaches 10.8 m³/h with hydraulic head extending to 19.4 m. The pump operates through a 230V single-phase induction motor rated at 0.75 kW with maximum absorbed power of 1.2 kW and operating current of 5.7 A. Operating speed remains approximately 2900 rpm through a two-pole motor configuration, supporting stable circulation performance during continuous-duty operation.
Hydraulic transfer is handled through a closed impeller arrangement designed for smooth movement of clean, non-abrasive liquids. Threaded suction and discharge ports manufactured according to ISO 228/1 standards simplify installation into compact pipe systems, while the direct motor-to-pump coupling reduces alignment requirements compared with separately coupled configurations.
Ceramic alumina and carbon mechanical seal faces operate together with EPDM elastomer components to support sealing performance under continuous operating conditions. The pump is suitable for liquid temperatures ranging from -10°C to +90°C with maximum permissible working pressure up to 10 bar. Motor protection includes IP54 enclosure protection, class F insulation, and an integrated thermal protector. Approximate unit weight is 11.9 kg.
