Drainage systems, irrigation transfer duties, and utility liquid handling applications requiring increased hydraulic output can utilize the Calpeda AM 50-125A. Its self-priming centrifugal arrangement supports dependable operation in systems where suction levels fluctuate or intake lines partially empty between working cycles.
Maximum flow handling extends to 33 m³/h while discharge head reaches 19.5 m, creating balanced delivery characteristics for larger-volume service duties. The hydraulic section is powered through a 240V single-phase motor delivering 1.5 kW rated output power and operating current of 10.4 A while maintaining rotational speed near 2900 rpm.
An open cast iron impeller supports unrestricted circulation while permitting suspended solids up to 10 mm to pass through the pump section. The self-priming system automatically re-establishes suction after dry periods or interrupted liquid supply, providing dependable hydraulic recovery without manual intervention.
Cast iron manufacture across the pump casing, impeller, lantern bracket, and cylindrical suction body ensures structural durability during continuous-duty operation. Shaft sealing relies on carbon ceramic seal faces combined with NBR elastomer support components, while the motor incorporates thermal overload protection, class F insulation, and IP54 environmental protection. Liquid handling suitability covers temperatures from -10°C to 90°C with maximum working pressure up to 6 bar.
