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 415V induction motor delivering 1.1 kW rated output power with an operating current of 2.6 A. Operating speed remains approximately 2900 rpm through a two-pole configuration, supporting smooth pressure generation and balanced flow transfer across continuous-duty operating conditions. Threaded ISO 228/1 suction and discharge ports simplify connection into service pipelines.
Flow stability is supported through a closed impeller arrangement engineered for reliable clean liquid transfer. Because the motor shaft is directly connected to the hydraulic assembly, alignment requirements are minimized and servicing access remains straightforward within compact installation environments. Stainless steel construction extends across the casing, impeller, shaft, and casing cover to help maintain corrosion resistance.
Ceramic alumina and carbon mechanical seal faces operate together with EPDM elastomer components to support sealing performance. Liquid temperature capability covers -10°C to +90°C with maximum permissible working pressure up to 10 bar. The three-phase motor incorporates class F insulation together with IP54 enclosure protection.
