Higher-pressure clean water circulation applications can utilize the Calpeda NMX 25/120A where compact centrifugal construction and corrosion-resistant hydraulic materials are required. The pump combines a close-coupled motor arrangement with AISI 304 stainless steel hydraulic components, supporting reliable handling of clean liquids that are non-aggressive toward stainless steel materials. Its configuration is suitable for industrial utility circulation, irrigation support systems, service water transfer, and continuous-duty process water movement where installation space is limited.
Hydraulic capability extends to a maximum head of 35.3 m with flow rates reaching 9.6 m³/h. The hydraulic section is powered by a three-phase 415V induction motor delivering 1.5 kW rated output power and operating at 4.3 A under rated conditions. Operating speed remains approximately 2900 rpm through a two-pole motor configuration, contributing to stable pressure development and balanced hydraulic transfer during prolonged operating cycles. Threaded suction and discharge ports manufactured to ISO 228/1 standards simplify integration into compact pipework systems.
A closed impeller arrangement controls movement of clean, non-abrasive liquids with dependable hydraulic transfer characteristics. Direct motor-to-pump coupling reduces alignment requirements and vibration compared with separately coupled pump assemblies. The casing, shaft, impeller, and casing cover are constructed entirely from AISI 304 stainless steel for robust long-term durability in wet environments.
Ceramic alumina and carbon mechanical seal faces operate with EPDM elastomer components for reliable shaft sealing performance. Maximum permissible casing pressure reaches 10 bar, with liquid temperature handling supported from -10°C to +90°C. The three-phase induction motor integrates class F insulation alongside IP54 enclosure protection. The suction connection size is G 1 1/4 while the outlet connection size is G 1.
