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-capacity transfer across wide distribution networks. The three-phase 415V induction motor delivers 4 kW rated output power while operating with rated current of 9.6 A at approximately 2900 rpm.
The open cast iron impeller allows passage of suspended solids up to 10 mm without restricting internal flow movement. The automatic self-priming system assists rapid recovery of suction capability after shutdown, helping avoid manual intervention when intake lines partially empty between operating cycles.
Mechanical durability is supported through cast iron manufacture of the casing, cylindrical suction body, impeller, and lantern bracket assembly. A carbon ceramic mechanical seal with NBR elastomer support materials provides dependable shaft sealing, while the close-coupled motor configuration integrates IP54 enclosure protection together with class F insulation. Operating temperatures from -10°C to 90°C are supported alongside maximum permissible working pressure up to 6 bar.
