Higher discharge performance for emulsions and moderately contaminated liquids is provided by the Calpeda CM 41 within medium-capacity centrifugal circulation systems. The open-impeller hydraulic arrangement supports unrestricted liquid movement across utility service installations and auxiliary hydraulic equipment where increased pressure capability is required.
Maximum head reaches 22.4 m while maintaining flow capacity up to 15 m³/h, supporting elevated hydraulic operation across larger circulation networks. The pump operates through a 230V single-phase induction motor utilizing 1.44 kW maximum input power with operating current of 7.4 A while maintaining rotational speed near 2900 rpm.
Stable internal liquid movement is assisted through an open impeller configuration capable of handling suspended particles up to 4 mm without obstructing hydraulic circulation. The centrifugal flow section supports dependable operating behaviour for lightly contaminated liquids during varying service demand.
Structural support is provided through cast iron manufacture of the casing and lantern bracket assembly. Mechanical shaft sealing utilizes carbon ceramic seal faces with NBR elastomer support materials, while the motor incorporates capacitor-start operation, internal thermal overload protection, class F insulation, and IP54 enclosure protection. Operating capability supports liquid temperatures from -10°C to 90°C with working pressure capability up to 6 bar.
