Orange Pumps CJ850-SW89 Cast Iron Shallow Well Jet Pump for Horticultural Irrigation with Single Impeller

Horticultural water distribution and rural irrigation are the primary service duties for this high-output self-priming jet pump, supplied with the SW89 injector, a balanced injector configuration suited to both pressure and flow. It is designed for properties requiring significant water volume delivered with consistent pressure from rivers or underground bores.

This model is powered by a high-performance 2.4 kW single-phase 240V motor that draws a rated current of 14.1 Amps. Hydraulic characteristics include a maximum flow rate of up to 146 L/Min and reaching a maximum head of up to 68 m. This performance profile provides a balanced solution for moving substantial liquid volumes over varied elevations across larger sites.

The SW89 injector works with the jet and venturi system to provide a balance of pressure and flow, utilising the large oval casing to maintain a constant water reservoir around the impeller, ensuring immediate suction establishment. This design is specifically engineered to handle installations with significant static head or long suction lines.

Built for longevity, the pump features a solid cast iron construction and a unique double race bearing system to manage mechanical stress. The motor is designed for full-load operation in high ambient temperatures and features a stainless steel shaft for enhanced corrosion resistance. The unit is rated for liquid temperatures reaching up to 65°C and includes a 2-year Orange Pumps warranty.
