Established in 1996, Dooch is a Korean booster pump manufacturer that mainly produces energy-saving electronic control pumps, booster pump systems, and industrial & household pumps. 

By localizing the pump-exclusive inverter and control device, which are the core technologies of electronic control pumps, Dooch has obtained NEP certification for booster pumps and excellent procurement product certifications for the first time in Korea. 

In addition, Dooch Chinese subsidiary and the Chinese Architectural Design Institute participated as responsible authors in the National Standard for digital-integrated individual inverter control booster pump system. The technology was applied from July 1, 2020.

The booster pump had already been designated as an excellent item through NEP (New Excellent Product) certification, which is a new technology certification system in Korea, and the pump technology has proven from China.
