Abstract:

A pump assembly for circulating water in an evaporative cooler is provided. The pump assembly may include a housing which defines a cavity. The pump assembly may also include an impeller received in the cavity of the housing. Further, the pump assembly may include a rod which may be operatively associated with the impeller and extends out of the housing. Moreover, the pump assembly may include a connecting member which is operatively associated with the rod, and may be adapted to be operatively associated with a shaft of a fan assembly incorporated into the evaporative cooler. The connecting member may be adapted to transmit rotary motion of the shaft to the impeller, thereby enabling the pump assembly to circulate water in the evaporative cooler.
