Large-volume water movement across irrigation networks, drainage pits, and utility transfer systems can integrate the Calpeda A 50-125B where dependable restart capability is important during changing suction conditions. The self-priming centrifugal arrangement supports movement of clean and slightly dirty liquids while restoring suction performance automatically after temporary interruption of liquid supply.
Hydraulic operation balances moderate discharge pressure with increased flow delivery, generating maximum head up to 15.5 m while moving up to 30 m³/h across the operating range. The three-phase 415V induction motor delivers 1.1 kW rated output power with operating current of 2.7 A and runs at approximately 2900 rpm for continuous-duty performance.
Liquid circulation is handled through an open cast iron impeller allowing passage of suspended solids up to 10 mm during operation. The self-priming configuration restores suction capability automatically after temporary stoppage or air entry into the suction pipeline, supporting continued hydraulic transfer without requiring manual intervention.
Structural components including the pump casing, lantern bracket, impeller assembly, and cylindrical suction body are manufactured from cast iron for operational rigidity. Carbon ceramic mechanical seal faces with NBR elastomer support elements control shaft sealing, while the motor assembly features class F insulation and IP54 enclosure protection. Liquid temperatures from -10°C to 90°C are supported alongside maximum permissible working pressure up to 6 bar.
