Utility circulation installations requiring increased discharge pressure can utilize the Calpeda NMXLM 25/90A where corrosion-resistant hydraulic materials and compact centrifugal construction are important operating considerations. The hydraulic section is manufactured in AISI 316L stainless steel for operation with liquids that are non-aggressive toward stainless steel materials while supporting continuous-duty clean liquid handling applications.
Maximum hydraulic head reaches 28.2 m with flow rates extending to 6.6 m³/h. The hydraulic assembly operates through a single-phase 230V induction motor rated at 1.1 kW with operating current of 7 A and maximum input power of 1.5 kW. Operating speed remains approximately 2900 rpm through a two-pole motor configuration supporting stable pressure generation during prolonged circulation duty.
Hydraulic transfer characteristics are controlled through a closed impeller arrangement intended for clean, non-abrasive liquids. Threaded ISO 228/1 suction and discharge ports simplify installation into compact utility circulation systems, while the direct-coupled motor arrangement minimizes alignment requirements within confined installation environments.
Ceramic alumina and carbon seal faces combined with EPDM elastomer elements support dependable sealing performance during continuous-duty operation. Motor construction incorporates class F insulation together with IP54 enclosure protection, while liquid temperature capability ranges from -10°C to +90°C with maximum permissible working pressure up to 10 bar.
