Aiming for further "customer safety continuous operation support service"
In 1955, we started manufacturing and selling mechanical seals for rotating machines such as pumps and agitators, and have continued for about 70 years under the motto of our company motto, "support service for customers' continuous safety operation." We have received high praise and trust from the market for our customer-oriented support that supports safe and stable operations through our directly managed service stations.
Our company was founded in 1955 when we succeeded in domestically producing carbon rings, which are the main components of mechanical seals. Since then, we have learned not only carbon, but also mechanical seal technology, and furthermore, how to handle it, with the guidance of our customers, through repeated training. We are proud that we are still contributing to society with our self-developed products such as porous carbon and support services.
In the future, we will continue to contribute to the realization of an earth-friendly social environment, including a carbon-neutral society, in the development of technologies, products, services, and materials, and continue to take on the challenge of being a company that is needed.
"If you tanken (explore), you will succeed"
Without forgetting this founding spirit, we will continue to refine our unique technical capabilities and contribute to meeting the needs of our customers and society.
