This is the replacement water pump for PolarCool 240V 48" evaporative coolers — it pushes water from the reservoir up to the cooling pads so the unit can produce cool air. If your 48" cooler's airflow feels warm or the pads are running dry, a worn pump is a common cause.
The 6422-0647 is a genuine PolarCool replacement pump built for the 240V 48" cooler line. It's a direct swap for the original unit, so you're restoring factory-designed water circulation rather than adapting a generic part. Note: If you would like to review the manufacturer Product Specifications, Warranty, Brochure, etc., for this system, please refer to the "Resources (System Manuals and Warranty)" Tab above on this page.
