Orange Pumps CJ750-SW57 Cast Iron 3-Phase Jet Pump for Farm Water Supply & Irrigation with Single Impeller

Stock trough supply and multi-line irrigation are the core service duties for this three-phase self-priming jet pump, supplied with the SW57 injector, a balanced injector configuration suited to both pressure and flow. It is designed for commercial rural properties requiring a 415V solution for balanced pressure and flow delivery over expansive sites.

The unit features a 1.5 kW three-phase 415V motor that draws a rated current of 3.5 Amps per phase for stable operation. Hydraulic characteristics include a maximum head of up to 58 m and a maximum flow rate of up to 122 L/Min. This balanced performance profile makes it ideal for facilities that manage simultaneous livestock watering and irrigation tasks.

The SW57 injector works with the jet and venturi system to deliver balanced pressure and flow while maintaining a low motor load, working with the large oval casing to maintain a constant water reservoir for purging air from the suction line. This design ensures the pump can quickly establish flow from surface sources with significant vertical suction lift requirements.

Mechanical durability is provided by a solid cast iron body and a specialised double race bearing system that shares the operational load. The three-phase motor is designed for continuous operation in high ambient temperatures and features a stainless steel shaft for enhanced corrosion resistance. The unit is rated for liquid temperatures reaching up to 65°C and is backed by a 2-year Orange Pumps warranty.

FEATURES

• Heavy-duty 1.5 kW three-phase 415V induction motor ensures high electrical efficiency and dependable service in commercial rural sites.
• Balanced SW57 injector design provides a versatile performance curve suitable for both pressurised distribution and high-flow transfer.
• Advanced double race bearing assembly provides superior mechanical support, significantly reducing motor wear in high-load applications.
• Solid cast iron construction offers enhanced structural durability and long-term protection against external environmental elements.
• Efficient self-priming design utilises a large-volume oval casing to facilitate immediate suction from bores or surface water sources.
• Precision stainless steel shaft protects the motor internals from rust while maintaining the alignment of the internal hydraulic components.
• TEFC protection ensures the motor remains isolated from environmental contaminants such as moisture, dust, and local vermin.
• Cast iron bearing end shield reduces vibration and bearing stress to promote quiet and stable operation during continuous duty cycles.
