With full Apex Fusion compatibility and a maximum flow rate of 2,000 gallons per hour, the COR-20 offers powerful, quiet, and energy-efficient water circulation—customizable from anywhere through your Apex controller.
Unlike conventional pumps, the COR-20 features advanced safety protocols, temperature monitoring, and fail-safe configurations that protect your system in real time. Its quiet, brushless motor design ensures long service life and dependable performance, making it the perfect choice for sump return, closed-loop circulation, or auxiliary pumping applications.
