Utility liquid movement and compact service circulation duties can be handled by the Calpeda C 20 through its cast iron centrifugal arrangement. The open-impeller geometry supports auxiliary equipment applications and industrial transfer duties where unrestricted liquid movement is preferred within confined installation spaces.
Operating performance reaches 4.8 m³/h maximum flow with discharge head extending to 12.3 m, supporting balanced low-to-medium pressure liquid handling across compact hydraulic systems. The unit operates through a three-phase 415V induction motor delivering 0.25 kW rated output power with operating current of 1 A while maintaining rotational speed near 2900 rpm.
Suspended particles up to 4 mm are permitted to pass through the open impeller arrangement without creating excessive internal flow restriction. The centrifugal hydraulic path assists stable circulation behaviour for moderately contaminated liquids under varying service conditions.
Cast iron manufacture across the hydraulic casing and lantern bracket assembly provides mechanical rigidity during operating service. Shaft sealing relies on carbon ceramic mechanical seal faces combined with NBR elastomer support components, while the motor assembly incorporates class F insulation and IP54 enclosure protection. Liquid temperatures from -10°C to 90°C are supported alongside maximum working pressure up to 6 bar.
