Orange Pumps CJ750-SW57 Cast Iron Shallow Well Pressure Pump for Rural Water Supply with 35 Litre Tank

Rural water supply and automatic property distribution are the primary service duties for this pressure pump system. It is designed for properties that require an automatic clean water supply from dams or shallow wells with a focus on both pressure and volume. The 35 litre pressure tank provides a solution for maintaining pressure across multiple troughs and irrigation lines automatically.

Operating on a 240v single-phase supply, the 1.5 kW motor delivers a rated current draw of 9.7 Amps. Hydraulic characteristics include a maximum flow rate of up to 122 L/Min and reaching a maximum head of up to 58 m. This balanced performance profile is suited to general-purpose agricultural tasks requiring automatic delivery for farm infrastructure.

This model is supplied with the WK-CJ30-50 water kit, which includes the Type D mechanical switch, pressure gauge, gate valve, and a 35 litre pressure tank. The SW57 injector works with the jet and venturi design to provide a balanced combination of pressure and flow while purging air from the casing for reliable self-priming. The pressure tank provides increased water draw-off between pump starts, helping reduce pump cycling and maintaining water availability for small demand.

Construction incorporates 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.
