People didn't always say “OKEN SEIKO, the best place for mini-pumps”

This only came to be after our tireless efforts.

We at OKEN SEIKO don't easily say we can't or won't. Every single one of our customer's requests is dealt with sincerity, squeezing out all our ideas and techniques in hopes of providing sufficient answers. These efforts have led our customers to call OKEN SEIKO the best place for mini-pumps. Our over 40-year journey wasn't without troubles. However, our pumps' miniaturization, quietness, and high durability, and our detailed responses to the needs of our clients, led to our current reputation.

We will not stop our pursuit of high-reliability in small parts capable of supporting the functions of devices such as Medical equipment, Automotive, Aircraft, and Home appliance.

Please leave your needs concerning the development and manufacturing of mini-air, vacuum, and liquid pumps to OKEN SEIKO. We'll handle your request regardless of how minor it may be. Feel free to contact us.
