Miller 35 GPH 150 PSI Coolant Pump with Bypass

Restore Your Cooler's Performance

Is your water cooler making noise or failing to circulate coolant? The Miller 226987 Coolant Pump is the direct OEM replacement you need to get your system back up and running. A functioning pump is the heart of your water-cooled setup, and when it wears out, your expensive torches are at risk of overheating and burning out. This pump is built tough to handle the daily grind of the welding shop, delivering a robust 35 gallons per hour to keep your equipment cool under fire.

Designed for easy installation into compatible Miller Coolmate units, this pump takes the guesswork out of repairs. It comes pre-set to 150 PSI, so you don't have to worry about calibration—just install it and get back to welding. The built-in bypass feature is a lifesaver; if you accidentally step on a coolant line or flow gets restricted, the pump won't burn itself out. It simply bypasses the pressure until the flow is restored. Trust genuine Miller parts to keep your shop running smoothly and your downtime to a minimum.
