Abstract
Evaporative cooler pump apparatus includes a generally round housing having a plurality of slots on the bottom of the housing which provides the function of an integral screen for the pump to screen out debris and which provides the function of absorbing vibration or dampening vibration to prevent motor vibration from being transmitted to the evaporative cooler in which the pump is disposed. The pump apparatus further includes a circular housing for the pump motor, and may include a wall above the pump motor separating the pump motor from a blower disposed above the motor. Cooled air is drawn upwardly over the motor and is expelled outwardly.
