Light industrial water pressure and automatic domestic supply are the core applications for this Junior Jet kit JJ400. It is specifically designed for small to medium households and rural properties requiring a reliable, high-pressure water source. The system manages clean water transfer from tanks, bores, and dams for continuous-duty domestic service.
Hydraulic performance for this 0.75 kW model reaches a maximum total head of 52 m and a maximum flow rate of 98 L/Min at 50Hz. Operating on a 240v single-phase supply, the motor draws a rated current of 4.5 Amps. These specifications establish the delivery capacity for standard pressure boosting and garden irrigation tasks.
Mechanical delivery is provided by a jet-assisted horizontal single-stage centrifugal assembly. This functional design facilitates shallow well lifts of 7.6m and deep well lifts up to 27m with appropriate injector combinations. The closed impeller system focuses on maximizing pressure output while maintaining high hydraulic efficiency.
Structural hardware consists of a heavy-duty Cast Iron pump casing and injector housing for mechanical durability. The internal assembly features a glass-filled polycarbonate impeller and a carbon/ceramic mechanical seal. This complete kit is supplied with a factory-fitted pressure switch and a 24L steel pressure tank for automatic operation.
