Dear, customers

I am SANG YOUNG JEONG Chairman of DOOCH Co., Ltd.
Thank you for sincerely visiting DOOCH Pump website.

Since our establishment in 1998, we extend our deepest appreciation to all customers who have placed their
trust in DOOCH Pump and continued to use our products. With the goal of strengthening technological
competitiveness in the pump industry, DOOCH has remained committed to a clear path—one driven by
technology and a spirit of challenge at its core.

DOOCH is a specialized pump manufacturer producing energy-saving electronically controlled pumps
(EPUMP) as well as industrial pumps. Through our in-house R&D center, we have successfully localized key
technologies of electronically controlled pumps, including pump-dedicated inverters and control systems.
Building on these achievements, we became the first company in Korea to obtain NEP certification for booster pumps
and to be recognized as an Excellent Procurement Product, growing into a technologyinnovation-driven enterprise.

As a recognized leader in electronically controlled pump technology in Korea, we will continue our unwavering commitment
to providing high-quality, competitive products and dependable services.

Looking ahead, we will actively expand into overseas markets under the "dooch" brand and strive to grow
into a global electronically controlled pump manufacturer representing Korea.
Thank you.
