Service installations handling clean or slightly dirty liquids with varying suction conditions can utilize the Calpeda B-A 50-125B for dependable self-priming hydraulic operation. The centrifugal pump arrangement assists liquid transfer duties where suction pipelines may partially drain between operating cycles, reducing the need for repeated external priming procedures.
Hydraulic performance reaches flow rates up to 30 m³/h with discharge head extending to 15.5 m, supporting increased transfer capacity across moderate-pressure utility and drainage applications. The pump operates through a three-phase 415V induction motor rated at 1.1 kW rated output power with operating current of 2.7 A while maintaining rotational speed near 2900 rpm.
Liquid circulation is managed through an open bronze impeller capable of passing suspended solids up to 10 mm without interrupting hydraulic movement. The integrated self-priming chamber assists restoration of suction capability automatically after temporary air entry or interruption of liquid supply within the suction line.
Bronze construction is incorporated throughout the casing, impeller, cylindrical suction body, and lantern bracket to support operation with liquids suited to bronze hydraulic materials. Shaft sealing utilizes carbon ceramic mechanical seal faces with NBR elastomer support components, while the close-coupled motor assembly integrates class F insulation together with IP54 enclosure protection. Operating suitability covers liquid temperatures from -10°C to 90°C with maximum permissible working pressure up to 6 bar.
