Higher-pressure clean water circulation systems can integrate the Calpeda NMXM 25/120A where compact single-phase centrifugal construction and stainless steel hydraulic materials are required. The pump supports operation with liquids that are non-aggressive toward AISI 304 stainless steel and is suited to irrigation systems, utility transfer duties, domestic circulation layouts, and civil service applications operating under continuous-duty conditions.
The hydraulic section develops maximum head up to 35.3 m while maintaining flow rates reaching 9.6 m³/h. A 240V single-phase induction motor delivering 1.5 kW rated output power supplies the hydraulic assembly and operates with an operating current of 9.2 A. Operating speed remains approximately 2900 rpm through a two-pole configuration supporting stable pressure delivery.
A closed impeller arrangement controls movement of clean, non-abrasive liquids with balanced hydraulic transfer characteristics. Threaded ISO 228/1 suction and discharge ports simplify integration into utility circulation systems, while the direct-coupled motor assembly minimizes alignment requirements and saves space.
Mechanical sealing is achieved through ceramic alumina and carbon seal faces operating with EPDM elastomer support elements. The motor assembly is constructed with class F insulation, IP54 protection, and integrated thermal protection for extended operating reliability. Allowable liquid temperatures range from -10°C to +90°C with maximum working casing pressure up to 10 bar.
