Moderate-flow clean liquid handling applications can utilize the Calpeda NMXM 25/120B where balanced discharge pressure and compact installation dimensions are required. The pump uses AISI 304 stainless steel hydraulic components for operation with liquids compatible with stainless steel materials and is suited to domestic circulation, irrigation support, civil service systems, and utility water movement applications.
Hydraulic performance reaches 27.8 m maximum head with flow rates extending to 9.6 m³/h. Power is supplied through a 230V single-phase induction motor rated at 1.1 kW with maximum absorbed power of 1.5 kW and operating current of 7 A. The two-pole motor arrangement operates near 2900 rpm and supports balanced pressure generation during continuous-duty operation.
A closed impeller arrangement manages movement of clean, non-abrasive liquids with stable hydraulic transfer characteristics. The close-coupled motor layout minimizes overall installation footprint, while threaded ISO 228/1 suction and discharge ports simplify connection into compact circulation pipe systems.
The casing, impeller, shaft, and casing cover are manufactured in AISI 304 stainless steel. Mechanical sealing incorporates ceramic alumina and carbon seal faces combined with EPDM elastomer components. The motor assembly uses class F insulation together with IP54 protection and integrated thermal protection. Liquid temperature capability ranges from -10°C to +90°C with maximum permissible working pressure up to 10 bar. Approximate unit weight is 13.6 kg.
