Rotary Piston Pumps

We began our operations as a wooden and cast mold manufacturer in 1950. Since then, we have used our expertise in technology to produce products that require high precision, such as automobile engine parts. We have supplied engine components, such as manifolds, to leading car brands like Mitsubishi Motors, Toyota, and Suzuki.

By using this technology, we manufacture pumps starting from the raw material stage. This means we have full control over all production stages. We monitor both the manufacturing and assembly of our pumps, ensuring that we meet the highest quality standards. Thanks to our unique manufacturing techniques and specially developed materials like Nakamura Metal No. 3, we continue to stay ahead of our competitors.

Currently, we are the market leader in Japan, and we export a large number of pumps to many countries worldwide. We continue to move forward with our vision of always ensuring “Technology & Reliability.”
