The Ebara Corporation traces its origins to the foundation of the Inokuty Type Machinery Office in 1912 and has been taking on social and technological challenges with a spirit of passion and dedication (netsu to makoto ) ever since. With an eye towards delivering its customers, and society as a whole, superior solutions to engineering problems, Ebara has evolved into a world leader for the production of environmental and industrial machinery. Along the way it has come to be recognised for developing an industry standard variety of products ranging from pumps to blowers, chillers and waste water machinery.
Founding Inokuty Type Machinery Office
The Inokuty Type Machinery Office was founded by Issey Hatakeyama with the goal of turning Dr. Inokuty’s world leading volute pump research into manufactured products. The logo of the office was designed after the name of Dr. Inokuty, who invented the Inokuty type volute pump.
The Founder: Issey Hatakeyama
Issey Hatakeyama was born in 1881 in Ishikawa Prefecture. He studied under Professor Ariya Inokuty, who was a world authority on volute pumps, at the College of Engineering, Tokyo Imperial University (the current University of Tokyo). Later, he established EBARA CORPORATION. He loved Noh plays and the tea ceremony, and was an avid art collector. He established the Hatakeyama Memorial Museum of Fine Art to make his art collection available to the general public.
The Professor: Dr. Ariya Inokuty, Tokyo Imperial University
Dr. Ariya Inokuty, Professor of Tokyo Imperial University, was born in 1856. In 1905, he published the article "The Theory of Volute Pumps", in which he systematically discussed the mechanism of centrifugal pumps. His article was applauded around the world as "the standard for theory on this kind of pump".
Receipt of an order for pumps of a record-breaking large-size from Tokyo City: Pumps manufactured on the basis of the theory and the technology
EBARA received an order for pumps of a large volute type with a diameter of 1,140 mm, a record-high at the time. The pumps, each weighing over 20 tons, were painstakingly completed. The factory lacked crane facilities and was so small that full machining work was not possible there. Therefore, after the pumps were assembled and tested, the crew chiseled, filed, and drilled holes in them, all by hand and on site. Currently, one of these pumps is placed on the premises of EBARA's head office as a monument symbolizing the spirit of "Netsu to Makoto (Passion and Dedication)".
Establishment of EBARA CORPORATION
The Office changed its name to EBARA CORPORATION in pursuit of expanding its business to other products in addition to the Inokuty type pump. The EBARA logo was designed by combining "荏" (The first character of EBARA in Japanese) with the pattern of a centrifugal pump impeller.

Production of the first axial-flow pump in Japan
Launch of production of pumps in Japan for city water
Making continuous efforts to promote the use of domestically-produced pumps, EBARA successfully proved that the performance of its pump was on par with that of foreign products in a comparison conducted at the Yodobashi water treatment plant in Tokyo. It consequently launched domestic production of pumps for city water.

EBARA technologies required by society
During the phase of economic recovery and rapid growth of Japan, EBARA faced an ever- increasing demand for advanced technologies from its customers. To respond to this demand, it strived to develop new products and technologies. It also made efforts to extend its business to segments such as compressors and turbines by actively introducing advanced technologies. In addition, it worked to develop products and technologies necessary for social infrastructure such as water and sewerage systems, stormwater drainage facilities, and waste incinerators, all of which were required to create a better society to live in.
Start of a plan for expansion of small-size pumps business through standardization and mass production
EBARA formulated a new strategy of mass production and sales of standard pumps, by standardizing the process for production and design of small-size pumps. The first standard pump was developed in 1956. Eventually, the product line was expanded to include multi-stage pumps and submersible pumps.

Construction of the Fujisawa Plant
EBARA established Japan's first system for mass production of standard pumps. In 1966, production of chillers also started there.
In 2008, the cumulative production volume of standard pumps reached over 15 million at the Fujisawa Plant.
Sales of the first super critical pressure feed water pump produced in Japan
The trend toward super critical pressure thermal power plants emerged due to the increasing demand for large-scale thermal power generation.
Entry into technical cooperation with Elliott Company for Elliott compressors
EBARA embarked on business in compressors for the petroleum refining/petrochemical industry.
Construction of the Sodegaura Plant
The Plant's mainstay products included Elliot's compressors and turbines.

Spread of EBARA technologies in society
EBARA developed a new business segment centered on semiconductor production that supports our advanced information society, as well as new products and technologies that meet the needs of society by saving energy and lowering environmental burdens. As developing countries have become the driving force in our global economy, EBARA's business has continued to spread across the globe.
Establishment of Corporate Logo (Current)
Taking the letter "E", the first in our name, as its motif, the Logo of EBARA CORPORATION is based on the following image targets as the backbones of the character of our corporate activities and our corporate stance.
Opening up the future of water, air, and the environment • High quality • Proactive • Internationally-minded • Diversity • Growth potential • A machinery engineering company • Dependability • New technologies
Movement into a new industry reflecting the trends of the times
Launch of a new business project for the semiconductor industry Targeting the semiconductor industry, which has a very short cycle of technological change, the Precision Machinery Business started to offer products necessary for semiconductor production. The list included dry vacuum pumps to create a clean production environment and chemical mechanical polishing (CMP) systems to produce nano-scale surface finishes.
