Orange Pumps CJ750-SW38 Cast Iron Jet Pump for Water Tank Filling & Transfer with Single Impeller

Rapid tank filling and high-volume rural water transfer are the primary service duties for this high-output self-priming jet pump, supplied with the SW38 injector, a high-flow injector configuration designed for maximum water volume. It is engineered for high-capacity applications where clean water needs to be moved quickly from surface sources such as rivers or large dams.

Powered by a 1.5 kW single-phase 240V motor, the unit draws a rated current of 9.7 Amps for reliable field activation. Hydraulic performance reaches up to 172 L/Min in flow and delivers a maximum head of up to 45 m. This performance profile establishes the unit as a high-output solution for moving significant volumes over moderate elevations.

The SW38 injector works with the jet and venturi system to maximise water volume while maintaining efficient self-priming performance, supported by a large oval casing that holds a substantial volume of water to assist with self-priming and ensure the pump can establish suction from bores or wells without delay. The uniquely shaped hydraulic components are designed to deliver maximum water volume with a low motor load.

Mechanical integrity is maintained by a solid cast iron body and a unique double race bearing system that shares mechanical loads across two rows of bearings. This design is particularly effective in high ambient temperatures where motor longevity is critical. The pump features a stainless steel shaft and is backed by a 2-year Orange Pumps warranty.

FEATURES

• Heavy-duty 1.5 kW induction motor provides the high torque required for continuous high-volume water transfer in agricultural settings.
• Optimised SW38 injector design is specifically calibrated to deliver maximum flow rates for rapid tank replenishment and site management.
• Heavy-duty double race bearing arrangement offers improved strength and longevity by effectively managing axial forces from the impeller.
• Large-volume oval pump casing simplifies the priming process by ensuring a constant water supply is available to purge air from lines.
• Solid cast iron construction provides a rigid and durable platform that resists environmental corrosion and mechanical impacts in the field.
• High-grade stainless steel motor shaft ensures a rust-free operation and maintains precise alignment of the internal hydraulic components.
• Inbuilt thermal protection automatically shuts down the motor in the event of overheating to prevent permanent electrical damage.
• TEFC motor protection ensures the internal windings remain isolated from dust, moisture, and vermin for long-term operational reliability.
