Portacool OK400 Evaporative Cooler Pump Replacement

Portacool OK400 Evaporative Cooler Pump Replacement is the official replacement pump assembly for the Portacool Cyclone OK400 portable evaporative cooler. In Portacool’s Cyclone parts catalog this item is listed as PUMP-CYC-3 and is documented in the Cyclone OK400 section of the owner’s manual as CYCLONE PUMP - OK400. The replacement component is designed to circulate water from the unit’s reservoir to the spray bar and cooling pads, enabling evaporation-based cooling that Portacool units rely on in hot conditions. By restoring proper water flow to the spray distribution path, the OK400 pump replacement supports consistent misting and pad wetting, which are essential for achieving the cooling performance expected from the Cyclone family. The PUMP-CYC-3 designation helps technicians verify they are installing the correct part for OK400 configurations, reducing downtime and helping maintain the unit’s original operating characteristics. This part is a targeted repair item for owners seeking to return their Cyclone OK400 to service after pump failure or routine maintenance, and it aligns with Portacool’s parts cataloging approach to model-specific replacement components.
