Orange Pumps CJ650-SW66 Cast Iron Shallow Well Jet Pump for High Pressure Farm Irrigation with Single Impeller

High-pressure water distribution and agricultural irrigation are the core applications for this self-priming shallow well jet pump, supplied with the SW66 injector, a high-head injector configuration designed for applications where discharge pressure takes priority over maximum flow. It is specifically configured for scenarios where clean water must be moved over elevated terrain or delivered through long pipe networks from dams or underground tanks.

Driven by a 1.1 kW single-phase 240V motor, the unit draws a rated current of 7.4 Amps during standard operation. 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 performance profile is optimised for high-head requirements where pressure delivery is prioritised over raw volume.

The SW66 injector works with the jet and venturi system to increase discharge pressure, with the large oval pump body maintaining a reservoir of water to ensure excellent self-priming behaviour by purging air locks. This design facilitates immediate water delivery upon startup, even in installations with high static suction lift.

Constructed for longevity, the pump utilises a cast iron bearing end shield and a stainless steel shaft to minimise mechanical stress. It incorporates specialised double race bearings that are better at handling the radial forces caused by water turbulence at varied flow rates. The assembly is rated for continuous duty with liquids up to 65°C and is backed by a 2-year Orange Pumps warranty.

FEATURES

• Robust cast iron construction ensures the pump remains a durable fixture in harsh outdoor agricultural and horticultural environments.
• Precision SW66 injector configuration is engineered specifically to maximise discharge pressure for high-head water distribution tasks.
• Large-capacity oval pump casing provides a significant water reservoir to ensure reliable self-priming and air purging from suction lines.
• Advanced double race bearing system provides superior support for the rotating assembly, reducing wear during high-pressure service cycles.
• Heavy-duty 1.1 kW motor is built for continuous service with a low operating temperature to help maintain low motor operating temperatures.
• Corrosion-resistant stainless steel shaft ensures a secure and durable connection between the motor and the hydraulic impeller.
• Standard thermal overload protection is integrated into the motor to safeguard against electrical failure or overheating during peak summer duty.
• Weatherproof TEFC motor housing provides critical protection against environmental contaminants including dust, moisture, and pests.
