Utility circulation duties requiring moderate-pressure liquid movement can integrate the Calpeda CM 4 for handling emulsions and lightly contaminated fluids within medium-capacity hydraulic systems. Its centrifugal open-impeller configuration supports stable liquid passage while maintaining compact installation characteristics.
Hydraulic capability extends to 15 m³/h maximum flow with head performance reaching 17.7 m, supporting increased discharge characteristics across larger circulation systems. Operation is supplied through a 230V single-phase induction motor utilizing 1.01 kW maximum input power with operating current of 5.7 A at approximately 2900 rpm.
Suspended particles up to 4 mm are accommodated within the hydraulic flow section through the open impeller arrangement without excessive internal restriction. The centrifugal circulation path supports dependable handling behaviour for moderately contaminated liquids during varying operating demand.
Mechanical rigidity is supported through cast iron construction of the casing and lantern bracket assembly. Carbon ceramic shaft seal faces with NBR elastomer support components assist reliable sealing performance, while the motor assembly incorporates capacitor-start operation, thermal overload protection, IP54 enclosure protection, and class F insulation. Liquid temperatures from -10°C to 90°C can be accommodated with permissible working pressure up to 6 bar.
