Orange Pumps CJ750-SW57 Cast Iron Jet Pump for Farm Water Supply & Irrigation with Single Impeller

Versatile farm water supply and stock trough replenishment are the core service duties for this self-priming jet pump, supplied with the SW57 injector, a balanced injector configuration suited to both pressure and flow. It is designed for rural properties that require a balance between high pressure for distribution and sufficient flow for watering livestock.

This model utilises a 1.5 kW single-phase 240V motor with a rated current draw of 9.7 Amps for efficient power management. Hydraulic output is characterised by a maximum flow rate of up to 122 L/Min and reaching a maximum head of up to 58 m. These parameters support a wide range of general-purpose agricultural tasks and medium-head water transfer requirements.

The SW57 injector works with the jet and venturi system to deliver balanced pressure and flow while maintaining a low motor load, allowing the pump to establish prime from surface sources. The large oval shape of the casing ensures that sufficient water is held around the impeller for immediate startup.

Construction includes a cast iron bearing end shield and a stainless steel shaft to minimise bearing stress and prevent corrosion. The inclusion of a double race bearing system ensures the motor can handle the radial forces caused by turbulence during high-velocity discharge. The unit is rated for liquid temperatures up to 65°C and includes a comprehensive 2-year Orange Pumps warranty.

FEATURES

• High-torque 1.5 kW motor is engineered to handle full-load service in remote locations with varied voltage supply conditions.
• Balanced SW57 injector configuration delivers an optimal mix of pressure and flow for versatile rural and agricultural applications.
• Innovative double race bearing technology enhances motor longevity by distributing radial and axial loads across dual bearing rows.
• Rugged cast iron pump body ensures enhanced structural stability and resistance to external environmental degradation.
• Integrated self-priming design utilises a large oval casing to maintain a consistent water reservoir for rapid air displacement.
• Stainless steel shaft construction protects the motor internals from corrosion and ensures long-term mechanical alignment.
• Standard thermal motor protection provides a critical fail-safe against overheating during continuous high-load pumping cycles.
• TEFC motor housing provides a robust barrier against environmental contaminants, ensuring internal electrical safety in outdoor sites.
