Orange Pumps CJ650-SW47 Cast Iron Shallow Well Pressure Pump for Stock Trough Supply with 18 Litre Tank

Automatic water supply for stock troughs and irrigation lines is the primary service duty for this pressure system. It is engineered for rural environments where clean water must be drawn from shallow wells, dams, or rivers to supply water on demand. The integration of a pressure tank makes it an ideal solution for installations requiring immediate, automatic water delivery.

Operating on a 240v single-phase power supply, the 1.1 kW motor draws a rated current of 7.4 Amps. Hydraulic output is defined by a maximum flow rate of up to 122 L/Min and reaching a maximum head of up to 43 m. These specifications support efficient water transfer across small to medium farm properties with varied suction lift conditions.

This model is supplied with the WK-CJ30-50 water kit, which includes the Type D mechanical switch, pressure gauge, gate valve, and an 18 litre pressure tank. The SW47 injector works with the jet and venturi design to provide a balanced combination of pressure and flow while purging air from the casing to assist self-priming. The pressure tank provides approximately 5.6 litres of water draw-off between pump starts, helping reduce pump cycling and maintaining water availability for small demand.

Construction features a solid cast iron body and a double race bearing system that helps the motor handle axial forces from the impeller and radial forces caused by water turbulence. The unit includes a stainless steel shaft, TEFC protection against dust and moisture, and a carbon ceramic shaft seal for reliable operation. The hydraulically tuned pump and integrated pump design generate maximum water flow and pressure while maintaining a low motor load.
