Where elevated transfer volume and stronger discharge pressure are required together, the Calpeda A 65-150A provides self-priming centrifugal operation for demanding utility and industrial liquid handling duties. The pump is suitable for movement of clean or slightly dirty water in systems exposed to changing suction conditions or intermittent operating cycles.
Maximum hydraulic flow reaches 57 m³/h while discharge head extends to 29 m, supporting efficient large-volume transfer across medium-pressure service applications. The hydraulic assembly is driven through a three-phase 400V induction motor rated at 4 kW output power with operating current of 9.6 A while maintaining rotational speed near 2900 rpm.
Liquid circulation is controlled through an open cast iron impeller engineered to accommodate suspended solids up to 10 mm during operation. Integrated self-priming functionality restores suction performance automatically whenever air enters the suction pipeline, assisting uninterrupted hydraulic transfer during variable operating conditions.
Cast iron construction across the pump casing, suction section, lantern bracket, and impeller provides structural strength during prolonged operating duty. Mechanical sealing incorporates carbon ceramic seal faces with NBR elastomer support materials, while the close-coupled motor assembly utilizes class F insulation together with IP54 environmental enclosure protection. Operating capability supports liquid temperatures between -10°C and 90°C with maximum permissible working pressure up to 6 bar.
