Orange Pumps CJ850-SW89 Cast Iron 3-Phase Jet Pump for Horticultural Irrigation with Single Impeller

Rural site management and irrigation are the intended applications for this three-phase self-priming jet pump, supplied with the SW89 injector, a balanced injector configuration suited to both pressure and flow. It is designed for commercial properties requiring a 415V solution for moving significant clean water volumes with substantial discharge pressure.

The unit features a 2.4 kW three-phase 415V motor with a rated current of 5.0 Amps per phase for stable and efficient performance. Hydraulic characteristics include a maximum head of up to 68 m and delivering a maximum flow rate of up to 146 L/Min. This balanced performance profile makes it ideal for large-scale agricultural distribution and facilities requiring high-velocity water movement.

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 significant water reservoir for purging air from long suction lines. This design ensures that the pump establishes prime quickly and maintains a stable discharge during intensive duty cycles.

Construction hardware includes a rugged cast iron pump casing and a unique double race bearing system to maximise mechanical longevity. The three-phase motor is designed for high-load service in high ambient temperatures and features a stainless steel shaft for enhanced rust protection. The unit is rated for liquid temperatures up to 65°C and is backed by a 2-year Orange Pumps warranty.

FEATURES
