Orange Pumps CJ850-SW77 Cast Iron Shallow Well Pressure Pump for High Static Head with 60 Litre Tank

Remote property supply and automatic long-distance water delivery are the intended service duties for this specialised high-head pressure system. It is designed for sites requiring an automated clean water supply drawn from underground wells or dams over expansive site elevations. The inclusion of a 60 litre pressure tank maximizes efficiency while overcoming pipeline resistance and significant vertical lift.

Driven by a 2.4 kW single-phase 240v motor, the unit operates with a rated current draw of 14.1 Amps during operation. Hydraulic performance is characterized by a maximum head of approximately 79 m and a maximum flow rate of 92 L/Min. This configuration is optimized for installations requiring maximum static head for automatic site water networks and irrigation tasks.

The system is factory-supplied with the WK-CJ850 water kit and a Type D mechanical switch integrated with a 60 litre pressure tank for automatic operation. The internal SW77 injector works with the jet and venturi design to maximize discharge pressure while purging air. The large 60 litre tank provides increased draw-off capacity, delaying pump starts for small demands and reducing wear on the motor.

Construction hardware includes a rugged cast iron casing and a double race bearing system to manage mechanical stress across dual bearing rows. The Type D mechanical switch contains no sensitive electronics, providing high resistance to power spikes or lightning typical of rural farm sites. The assembly is rated for liquids up to 65°C and includes a comprehensive 2-year manufacturer warranty.
