This is the 120V water pump that circulates water from the reservoir to the cooling pads on your PolarCool 48" evaporative cooler. If your unit's pump has failed or is delivering weak, uneven pad saturation, this is the direct replacement part — but only for the correct chassis and voltage, so check compatibility below before you order.
Water pumps in evaporative coolers see continuous duty cycles — they run whenever the cooling function is active, which makes them one of the more common wear items in a swamp cooler or portable evaporative unit. This 120V pump is built to restore pad wetting and consistent evaporative performance in PolarCool 48" systems. 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.
Critical Fitment & Requirements
- 120V pump — designed for PolarCool 48" Model units only.
- Compatible with SKU 6622-1310 only. Verify your unit's model/part reference before ordering.
- Does NOT fit 240V 48" models — those require the 240V pump, SKU 6422-0647.
- Not confirmed for use with any PolarCool model other than SKU 6622-1310.
Mismatched voltage is the most common return reason on evaporative cooler pumps — installers grab the pump on the shelf without confirming whether the unit is a 120V or 240V build, and it either fails to run or trips a breaker on first startup. Before you disconnect the old pump, trace the supply wiring back to the unit's data plate and confirm actual voltage, not just the model number on the housing. Use a multimeter to verify line voltage at the pump connector before energizing the replacement. This matches standard field-service practice for line-voltage verification prior to component swap, and it prevents a second truck roll for the wrong part.

FAQ
Will this pump fit my 48" PolarCool cooler?
It fits PolarCool 48" units that use SKU 6622-1310 and run on 120V power only. Verify your unit's part reference before ordering.
What voltage is this pump rated for?
This pump is a 120V unit. If your 48" model runs on 240V, you need SKU 6422-0647 instead.
Can I use this pump on a 240V 48" model?
No. The 240V 48" models require the 240V pump, SKU 6422-0647. This 120V pump is not interchangeable with that voltage.
Is this a genuine PolarCool part?
Yes. This is a genuine PolarCool replacement component, Part No. 6422-1310.
