Orange Pumps CJ850-SW77 Cast Iron 3-Phase Shallow Well Pressure Pump for High Static Head with 60 Litre Tank

Static head distribution and automated water supply for vast site networks are the core service duties for this three-phase pressure pump. It is engineered for rural properties where clean water from dams or wells must be moved automatically over extreme terrain distances. The inclusion of a 60 litre pressure tank ensures that discharge pressure is available immediately while maximizing system efficiency.

The system features a 2.4 kW motor drawing 5.0 Amps per phase on a 415v three-phase supply for stable site activation. Hydraulic performance is characterized by a maximum head of approximately 79 m and delivers a maximum flow rate of 92 L/Min. This high-pressure profile is specifically optimized for overcoming vertical lift in automated property water networks.

Factory-fitted with the WK-CJ850 water kit and a Type D mechanical switch, the system includes a 60 litre pressure tank for automatic management. Its internal high-head SW77 injector works with the jet and venturi design to maximize pressure while effectively purging air from the casing. The 60 litre tank volume provides increased draw-off capacity to significantly reduce cycling and save wear on the motor.

Mechanical durability is provided by a solid cast iron body and a double race bearing system that protects the motor from axial forces. The Type D mechanical switch contains no sensitive electronics, providing high resistance to the effects of lightning and power surges common in remote areas. The unit handles liquid temperatures up to 65°C and includes a 2-year warranty.
