Industrial Hydraulic Department

Sumitomo Precision 's hydraulic control technology, which was originally developed for aircraft equipment, is now being applied to a variety of fields.
We entered the industrial equipment field in 1962. Since then, our applications have expanded to include not only civil engineering and construction machinery, steelmaking machinery, rolling mills, ships and high-speed craft, but also presses, injection molding machines, machine tools, and more.

Nowadays, as business as a whole becomes more globalized, the scope of our customers' activities is expanding worldwide, and as a pump manufacturer we are required to have a variety of global response capabilities.

We will continue to push forward with the goal of becoming the global No. 1 pump manufacturer in terms of "comprehensive strength" and "competitiveness."
