Utility drainage installations and clean water transfer systems can integrate the Calpeda A 50-125C where self-priming centrifugal performance is required. The pump handles clean or slightly dirty water and is suited to applications where fluctuating suction conditions may cause pipelines to partially empty between operating cycles.
Maximum flow capacity extends to 27 m³/h while discharge head reaches 12.8 m, supporting balanced liquid movement across medium-capacity transfer systems. Power is supplied through a three-phase 415V induction motor delivering 0.75 kW rated output power with operating current of 2.3 A and rotational speed near 2900 rpm.
An open cast iron impeller assists unrestricted liquid movement while allowing suspended solids up to 10 mm to pass without interrupting hydraulic circulation. Stable transfer performance is maintained during fluctuating liquid levels through the integrated self-priming configuration and anti-siphon operating behaviour.
Mechanical strength is supported through cast iron manufacture of the casing, lantern bracket, cylindrical suction section, and impeller assembly. Carbon ceramic mechanical seal faces operate together with NBR elastomer support components for shaft sealing stability, while the close-coupled motor incorporates class F insulation and IP54 enclosure protection. Operating capability supports liquid temperatures from -10°C to 90°C with maximum permissible working pressure up to 6 bar.
