Pressure-oriented shallow well extraction and clean water transfer applications can integrate the Calpeda NG 5/16 self-priming jet pump for dependable operation across residential, agricultural, and utility service systems. The integrated ejector arrangement supports stable suction capability for installations requiring elevated discharge pressure and reliable priming performance.
Hydraulic output reaches 59 m maximum head with flow rates extending to 4.5 m³/h, supporting efficient pressure delivery across medium-demand water distribution systems. The three-phase 400V induction motor provides 1.1 kW rated output power with operating current of 2.7 A while maintaining approximately 2900 rpm rotational speed for continuous-duty operation.
Flow movement is controlled through a brass impeller arrangement supporting stable jet-assisted hydraulic transfer of clean liquids and slightly dirty surface water. Noryl diffuser and nozzle sections contribute to controlled internal circulation characteristics while assisting efficient suction performance during varying operating demand.
Cast iron construction across the pump casing, casing cover, and diffuser plate provides structural support for prolonged operating conditions. Mechanical sealing incorporates carbon ceramic faces with NBR elastomer support elements, while the motor assembly integrates class F insulation and IP54 protection. Operating capability supports liquid temperatures up to 40°C with maximum permissible working pressure reaching 10 bar.
