Clean and slightly dirty liquid transfer duties in utility, drainage, and service installations can be handled by the Calpeda B-A 50-125C through its self-priming centrifugal hydraulic arrangement. The pump is suited to operating conditions where suction lines may not remain fully flooded between working cycles, allowing recovery of pumping action without repeated manual priming intervention.
Hydraulic output reaches flow rates up to 27 m³/h while developing discharge head up to 12.8 m, supporting high-volume liquid movement under moderate-pressure operating conditions. A three-phase 415V induction motor supplies 0.75 kW rated output power with rated current of 2.3 A while maintaining operating speed near 2900 rpm.
Stable hydraulic transfer is maintained through an open bronze impeller designed to pass suspended solids up to 10 mm without restricting circulation. The self-priming chamber arrangement assists evacuation of air from the suction circuit during startup while supporting dependable hydraulic recovery after temporary interruption of liquid supply.
Bronze construction is utilized across the casing, impeller, cylindrical suction section, and lantern bracket for compatibility with liquids suited to bronze hydraulic materials. Mechanical sealing incorporates carbon ceramic seal faces together with NBR elastomer support elements, while the close-coupled motor assembly integrates class F insulation and IP54 enclosure protection. Liquid handling capability covers temperatures from -10°C to 90°C with permissible working pressure up to 6 bar.
