Orange Pumps CJ850-SW77 Cast Iron 3-Phase Shallow Well Pressure Pump for High Static Head with 35 Litre Tank

Expansive site distribution and overcoming static head are the primary service duties for this three-phase high-head pressure pump. It is designed for properties where clean water from underground sources or dams must be moved automatically over significant terrain distances. The inclusion of a 35 litre pressure tank provides a solution for maximizing efficiency in high-pressure automatic networks.

This model features a 2.4 kW motor operating on a 415v three-phase supply with a rated current draw of 5.0 Amps per phase. Hydraulic output is characterized by a maximum head of approximately 79 m and a maximum flow rate of 92 L/Min. This high-pressure configuration is optimized for overcoming pipe resistance and vertical lift in automated site water management.

Factory-fitted with the WK-CJ850 water kit and a Type D mechanical switch, the system utilizes a 35 litre pressure tank for automated operation. Its internal SW77 injector works with the jet and venturi design to maximize discharge pressure while purging air. The 35 litre tank ensures a 10.8 litre draw-off is available to satisfy small demands without triggering a full pump cycle.

Built for durability, the pump features a solid cast iron body and a double race bearing system that shares the motor load across two rows. The Type D mechanical switch contains no sensitive electronics, providing high resistance to power surges and lightning common in remote agricultural areas. The unit handles liquid temperatures up to 65°C and includes a comprehensive 2-year Orange Pumps warranty.
