History
~Supporting our customers' safe continuous operation was also the beginning of TANKEN's history~
TANKEN SEAL SEIKO was founded after solving a customer's problem.
Since then, we have gained trust by responding to customer problems and have grown into what we are today.
1954
Masao Nagai, a pioneer of carbon, successfully solved a production problem caused by abnormal wear of mechanical seals installed in foreign-made pumps at a refinery in Yokohama by applying a carbon ring he developed himself.
1955/5
After being recommended by a customer, he founded Carbon Research Institute Co., Ltd.
We immediately began manufacturing carbon rings, the heart of mechanical seals.
Shortly thereafter, at the suggestion of a customer, we began manufacturing mechanical seals.
1959/5
The company was renamed Tanken Kogyo Co., Ltd.
1964/5
The company was renamed Tanken Seiko Co., Ltd.
As new plants are being built and expanded, our sincere response to all mechanical seal problems has been highly praised, and our adoption has expanded rapidly. At the same time, we have established a nationwide technical service network.
1993/10
The company name was changed to TANKEN SEAL SEIKO Co., Ltd.
The aim is to provide "support services for users' continuous safety operations."

2020/12
After much research starting about five years ago, the company developed a floating transport device that utilizes the carbon technology of its original business and exhibited it at an exhibition. The overwhelming response prompted the company to fully commercialize the floating transport device that utilizes carbon technology.
