Orange Pumps CJ850-SW89 Cast Iron Shallow Well Pressure Pump for Garden Irrigation with 35 Litre Tank

Horticultural irrigation and automatic site distribution are the core duties for this high-performance single-phase pressure pump. It is designed for properties requiring an automated clean water source with a focus on consistent discharge pressure. The integration of a 35 litre pressure tank ensures that irrigation networks maintain steady flow with reduced pump cycling.

Driven by a 2.4 kW single-phase 240v motor, the unit operates with a rated current of 14.1 Amps for stable site-wide supply. Hydraulic characteristics include reaching a maximum head of approximately 68 m and delivering a maximum flow rate of 146 L/Min. This performance profile is ideally suited to nursery and agricultural applications requiring pressurised delivery over varied elevations.

Equipped with the WK-CJ850 water kit and a Type D mechanical switch, the system utilizes a 35 litre pressure tank for automated management. Its internal SW89 injector is hydraulically tuned for balanced pressure and flow, while the jet and venturi design purges air from the casing. The 35 litre tank maintains a 10.8 litre draw-off reservoir, saving significant wear and energy costs over time.

Mechanical durability is provided by a solid cast iron body and a double race bearing system that shares the motor load across two rows. The Type D mechanical switch is engineered for high electrical tolerance against surges common in remote areas. The entire assembly is rated for liquids up to 65°C and is backed by a 2-year Orange Pumps warranty on all major components.
