Utility water movement and clean liquid circulation systems can integrate the Calpeda NMX 25/70A where compact centrifugal construction and corrosion-resistant hydraulic materials are required. The pump uses a close-coupled design with AISI 304 stainless steel hydraulic components, supporting operation with clean, non-abrasive liquids that are compatible with stainless steel materials. Its reduced installation footprint makes it suitable for civil, industrial, irrigation, and general service applications where stable continuous circulation is necessary.
The hydraulic section delivers flow rates up to 5.4 m³/h with maximum head reaching 25.8 m. A three-phase 400V induction motor rated at 0.75 kW operates at 2.2 A and drives the pump through a two-pole configuration running at approximately 2900 rpm. This operating arrangement supports balanced pressure generation and controlled liquid transfer across continuous-duty service conditions. Threaded ISO 228/1 suction and discharge connections simplify installation into utility pipe systems and compact circulation layouts.
Liquid transfer is managed through a closed impeller configuration engineered for smooth hydraulic movement with clean fluids free from abrasive content. The impeller, shaft, casing, and casing cover are manufactured in AISI 304 stainless steel, contributing to corrosion resistance and hydraulic consistency during extended operating cycles. Because the motor and hydraulic section are directly coupled, alignment complexity is minimized while servicing access remains straightforward in confined installation environments.
Ceramic alumina and carbon mechanical seal faces operate together with EPDM elastomer components to support reliable sealing performance. 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 with IP54 enclosure protection, supporting dependable operation in utility and industrial service conditions. The inlet connection size is G 1 1/4 and the outlet connection size is G 1.
