Applications requiring increased clean water circulation capacity can integrate the Calpeda NMX 25/120C where stainless steel hydraulic construction and compact centrifugal design are important installation considerations. The pump is configured with a close-coupled motor arrangement that reduces overall installation space while supporting reliable operation with liquids that are non-aggressive toward AISI 304 stainless steel materials. Its hydraulic layout is suited to utility circulation, irrigation support, service water handling, and industrial transfer systems operating under continuous-duty conditions.
Maximum hydraulic output reaches 10.8 m³/h with head capability extending to 19.4 m. The hydraulic section is driven by a three-phase 400V induction motor rated at 0.75 kW with operating current of 2.2 A. A two-pole motor operating at approximately 2900 rpm supports smooth circulation characteristics and stable flow transfer during prolonged operating cycles. Threaded suction and discharge connections manufactured to ISO 228/1 standards simplify installation into utility pipe systems and compact circulation assemblies.
Hydraulic transfer is managed through a closed impeller arrangement intended for balanced movement of clean, non-abrasive liquids. The casing, shaft, impeller, and casing cover are manufactured in AISI 304 stainless steel, contributing to corrosion resistance and long-term hydraulic stability in service water applications. Because the motor and hydraulic assembly are directly coupled, alignment requirements are minimized while maintenance access remains straightforward in confined installation environments.
Mechanical sealing incorporates ceramic alumina and carbon seal faces together with EPDM elastomer support components. The pump is suitable for liquid temperatures ranging from -10°C to +90°C with maximum permissible working pressure up to 10 bar. Motor construction includes class F insulation and IP54 enclosure protection for continuous-duty operation in industrial and utility service conditions. The inlet connection size is G 1 1/4 and the outlet connection size is G 1.
