▼ History
Since its inception in 1953, the company has been contributing to the development of Japan’s major industries, such as petroleum refining, petrochemical, electric power, steelmaking, and shipbuilding, as well as public work projects, through designing, manufacturing, and selling of pumps, compressors, and steam turbines under the Worthington brand. Today’s Niigata Worthington, as a member of Flowserve Corporation group, has established a structural system to supply optimum, world-class pumps such as Worthington, Ingersoll-Dresser, Pacific, Byron Jackson, Pleuger, and Durco.
In 1987, Niigata Worthington founded Niigata Equipment Maintenance Co., Ltd. (NEMCO) specializing in the maintenance of rotating equipment. Consequently, the company focuses on not only the manufacture of equipment, but also on equipment diagnosis, consulting, repair, and maintenance services, which are highly rated by many industries ranging from petroleum refining and chemical, to nuclear power generation. In recent years, the company has been steadily achieving results in the fields of ultrahigh-performance centrifuges, water turbines for ecological power generation, wind turbines, etc. We intend to make a leap in the 21st century to become an enterprise that customers value, by developing and manufacturing various types of rotating equipment in response to the requirements of the times, and by striving to increase efficiency in rotating equipment maintenance.
