Balanced clean water transfer and circulation duties can be handled by the Calpeda NMX 25/120B, a close-coupled centrifugal pump combining moderate flow capacity with increased pressure capability. The hydraulic section is manufactured in AISI 304 stainless steel, supporting reliable operation with clean liquids that are non-aggressive toward stainless steel materials. Its compact construction allows integration into utility circulation systems, irrigation layouts, industrial service lines, and general water movement applications where installation space is limited.
The pump develops maximum head up to 27.8 m while supporting flow rates extending to 9.6 m³/h. Hydraulic performance is driven by a three-phase 400V induction motor rated at 1.1 kW with operating current of 2.6 A. Operating speed remains approximately 2900 rpm through a two-pole motor configuration, contributing to stable pressure generation and balanced hydraulic transfer during continuous-duty operation. ISO 228/1 threaded suction and discharge connections support simplified installation into compact circulation pipework systems.
Liquid movement is controlled through a closed impeller arrangement engineered for smooth handling of clean, non-abrasive fluids. Stainless steel construction across the casing, shaft, impeller, and casing cover contributes to corrosion resistance and hydraulic stability during extended operating cycles. The direct-coupled motor and hydraulic assembly minimizes alignment complexity while allowing easier servicing access in confined installation environments.
Sealing performance is supported through ceramic alumina and carbon mechanical seal faces combined with EPDM elastomer components. The pump is suitable for liquid temperatures from -10°C to +90°C with maximum permissible working pressure up to 10 bar. Class F insulation together with IP54 motor enclosure protection supports dependable operation in utility and industrial service environments. The inlet connection size is G 1 1/4 while the outlet connection size is G 1.
