All our pumps are proudly Made in the USA!
If the unit is a rebuilt pump, please note it was professionally reconditioned by a U.S. rebuilder near Denver, CO, between the late 1980s and early 1990s.
Regarding Photos: Due to our volume of identical, interchangeable inventory, we use representative stock photos for this model. The image is for reference only and may depict a specific manufacturer (e.g., 'AC'). You will receive a pump that meets all listed specifications, which may be from the manufacturer shown or a fully equivalent alternative.
