High-volume drainage and liquid transfer duties can integrate the Calpeda AM 50-125C where dependable self-priming operation is required in utility, irrigation, and civil service installations. The hydraulic configuration supports movement of clean and slightly dirty liquids while maintaining automatic suction recovery after shutdown periods or temporary interruption of suction conditions.
Hydraulic capacity reaches flow rates up to 27 m³/h with maximum head extending to 12.8 m, supporting efficient transfer of larger liquid volumes across low-pressure operating systems. The pump operates through a 240V single-phase induction motor delivering 0.75 kW rated output power with rated current of 5.8 A while maintaining operating speed near 2900 rpm.
Liquid circulation is maintained through an open cast iron impeller arrangement capable of handling suspended solids up to 10 mm without restricting hydraulic movement. The self-priming centrifugal design supports dependable restart performance during intermittent-duty operation while assisting stable liquid transfer where varying suction levels are encountered.
Cast iron construction across the casing, lantern bracket, cylindrical suction section, and impeller assembly contributes structural rigidity during prolonged operating duty. Shaft sealing is controlled through carbon ceramic mechanical seal faces with NBR elastomer components, while the single-phase motor integrates internal thermal protection, IP54 enclosure protection, and class F insulation. Operating capability covers liquid temperatures from -10°C to 90°C with permissible working pressure up to 6 bar.
