Orange Pumps CJ850-SW77 Cast Iron Shallow Well Jet Pump for High Head Water Supply with Single Impeller

Long-distance water supply and high-head distribution are the core applications for this high-output self-priming jet pump, supplied with the SW77 injector, the highest-head injector available in the CJ range. It is specifically engineered for rural properties where clean water must be moved over significant elevations or through extensive pipe networks from deep bores or dams.

Driven by a powerful 2.4 kW single-phase 240V motor, the unit operates with a rated current draw of 14.1 Amps. Hydraulic performance is defined by a maximum head of up to 79 m and delivers a maximum flow rate of up to 92 L/Min. This high-pressure configuration is optimised for applications requiring the highest head within the CJ range.

The SW77 injector is designed to work with the jet and venturi system to increase discharge pressure, utilising the large oval pump casing to hold a substantial volume of priming water to ensure that air locks are purged and suction is established rapidly upon startup. This design ensures stable hydraulic performance even in installations with extreme suction lift requirements.

Construction hardware includes a solid cast iron body and a unique double race bearing system that provides reliable mechanical support for the motor. The assembly features a high-grade stainless steel shaft and TEFC motor protection for reliable operation in high ambient temperatures. The unit is rated for liquid temperatures up to 65°C and includes a comprehensive 2-year Orange Pumps warranty.

FEATURES

• 2.4 kW induction motor provides the power required for high-head rural water management tasks.
• Specialised SW77 injector configuration is engineered for maximum vertical lift and pressurised delivery over expansive sites.
• Heavy-duty double race bearing design ensures enhanced motor longevity by distributing heavy axial and radial operational loads.
• Rugged cast iron casing offers improved structural strength and long-term resistance to environmental corrosion in farm sites.
• Advanced self-priming mechanism utilises a large oval-shaped pump body to ensure quick and reliable suction establishment.
• Corrosion-resistant stainless steel motor shaft protects the assembly from rust and maintains precise internal hydraulic alignment.
• Integrated thermal protection automatically safeguards the motor windings from damage caused by abnormal high-pressure load cycles.
• TEFC motor housing provides an effective barrier against dust, moisture, and pests to maintain consistent electrical performance.
