Orange Pumps CJ650-SW66 Cast Iron Shallow Well Pressure Pump for Pressurised Irrigation with 35 Litre Tank

Pressurised irrigation and automatic high-pressure water delivery are the core applications for this shallow well pressure system. It is engineered for rural sites where clean water from dams or wells must be automatically moved over significant elevations or through long pipelines. The larger pressure tank ensures that irrigation systems maintain stable pressure with fewer pump interventions.

Driven by a 1.1 kW single-phase 240v motor, the unit operates with a rated current draw of 7.4 Amps. Hydraulic performance is defined by a maximum head of up to 54 m and delivers a maximum flow rate of up to 70 L/Min. This high-pressure profile is designed for applications where vertical lift and discharge head are the primary system requirements.

This model is supplied with the WK-CJ30-50 water kit, which includes the Type D mechanical switch, pressure gauge, gate valve, and a 35 litre pressure tank. The SW66 injector works with the jet and venturi design to provide higher discharge pressure while purging air from the casing for reliable self-priming. The pressure tank provides increased water draw-off between pump starts, helping reduce pump cycling and maintaining water availability for small demand.

Construction incorporates a solid cast iron body and a double race bearing system that helps the motor handle axial forces from the impeller and radial forces caused by water turbulence. The unit includes a stainless steel shaft, TEFC protection against dust and moisture, and a carbon ceramic shaft seal for reliable operation. The hydraulically tuned pump and integrated pump design generate maximum water flow and pressure while maintaining a low motor load.
