Replacement Bonaire evaporative cooler pumps for Bonaire, Celair and Climate Tech coolers, including genuine Fasco JRM28, JRM38 and JRM50 pumps. If your cooler blows warm air and the pads stay dry, the pump is a likely cause.
Frequently asked questions
How do I know which Bonaire pump I need?
The number on your old pump’s label tells you which size you need, so replace like for like. This range includes the Fasco E/P28 JRM28, E/P38 JRM38 and E/P50 JRM50 pumps for Bonaire and Celair coolers.
How do I know if my evaporative cooler pump is working?
With the cooler running in cooling mode, the pads should be evenly wet within a few minutes. If the pads stay dry, or the pump hums without water flowing, the pump or water supply has a problem.
Why is my cooler pump running but the pads are dry?
Common causes are a blocked pump inlet, a blocked water distribution pipe or spreader, or a low water level. The evaporative cooler pump guide walks through the checks.

About Bonaire & Celair evaporative cooler pumps
The pump lifts water from the cooler tank up to the distribution system so the filter pads stay evenly wet. When it fails, the cooler still blows air but it will not cool, and you may hear a hum with no water flowing.
Most Bonaire and Celair roof-mounted coolers use a Fasco JRM-series pump. The JRM38 suits most Bonaire Integra and Celair models, the JRM28 suits smaller units, and the JRM50 suits the larger high-flow models. Check the label on your old pump or the model plate on the cooler to confirm the right part.
Before replacing a pump, clean the pump inlet screen and check the water level. A blocked screen or a stuck float valve can look like a failed pump.
