Little Giant CP3-230 Evaporative Cooler Pump

The Little Giant CP3-230 Evaporative Cooler Pump is a heavy-duty, 1/30 HP replacement unit engineered for high-demand HVAC cooling systems. Pro-grade 230V swamp cooler pumps like the CP3-230 are designed to handle commercial evaporative cooling applications up to 21,000 CFM, providing a maximum flow rate of 563 GPH at a 1-foot head. This concentric fan-cooled replacement pump features moisture-proof windings and a corrosion-resistant one-piece steel motor shaft to withstand constant moisture exposure. The 12-foot shut-off head ensures reliable vertical lift, while the snap-off volute plate and mesh debris screen simplify routine maintenance on the job site. With universal mounting configurations and a 90-degree barbed elbow, this high-capacity cooler pump offers seamless integration into existing equipment, making it a reliable choice for contractors managing large-scale recirculating water systems and industrial displays.

Key Benefits

• High-Volume Performance: Rated for systems up to 21,000 CFM, delivering 563 GPH at 1' and 231 GPH at 10' for consistent pad saturation.
• Industrial Build Quality: Features a flame-retardant housing and thermal overload protection to prevent motor failure during peak operation.
• Service-Friendly Design: Tool-free snap-off volute and removable mesh screen allow for rapid cleaning of mineral deposits and debris.
• Simplified Installation: Universal mounting bracket and a 90-degree barbed elbow compatible with 5/8" and 3/4" I.D. flex tubing.

Common Questions

Is the CP3-230 compatible with residential 115V outlets?
No, this specific model is wound for 230V operation. Ensure your power supply matches the 230V requirement to avoid immediate motor damage.

Can this pump be used in 15,000 CFM units?
Yes, while it is optimized for units up to 21,000 CFM, its 1/30 HP motor provides excellent performance for 15,000 CFM commercial coolers requiring high lift or faster turnover.

How do I prevent the pump from clogging with hard water scale?
The integrated mesh debris screen captures larger particles, but regular flushing of the snap-off volute is recommended to maintain the 5.2 PSI pressure rating.
