Fast-moving clean water applications require more than basic transfer capability, especially where suction conditions fluctuate or rapid priming performance is essential. The Calpeda NGXM 4/22 combines high-flow hydraulic performance with self-priming jet pump operation, making it suitable for water circulation duties, garden distribution systems, and above-ground transfer arrangements.
Producing flow rates up to 140 L/Min with maximum head reaching 34.8 m, the pump supports efficient clean water movement across irrigation layouts, washing stations, and pressure-assisted supply systems. Its integrated ejector system assists automatic priming performance while maintaining suction lift capability up to 9 m during shallow-well operation.
Hydraulic stability is enhanced through an exclusive diffuser geometry paired with an integrated flow control device that assists in minimizing turbulence and lowering running noise. Internal air evacuation around the mechanical seal also contributes to operational reliability by helping reduce seal stress during temporary abnormal suction conditions.
The compact close-coupled construction simplifies installation where available space is restricted while supporting retrofit suitability across existing systems. Both the casing and casing cover are manufactured from AISI 304 stainless steel for corrosion resistance, while the brass impeller supports durable hydraulic efficiency across demanding clean water applications.
Single-phase 230V operation includes integrated thermal motor protection together with IP54 enclosure protection and Class F insulation. Continuous-duty operation is supported for liquid temperatures up to 35°C with maximum permissible casing pressure reaching 8 bar.
