Strengths of the Hydraulic Control Division

• Achieving high levels of efficiency and energy-saving performance
• Internal gear structure that achieves low pulsation and low noise
• Hydraulic and control technologies cultivated over many years

Hydraulic Equipment and Control Systems

Sumitomo Precision 's hydraulic pumps (QT pumps), which use special internal gears, have excellent performance, such as low pulsation and low noise, and are therefore being used in a wide range of fields, including injection molding machines, Precision presses, and various hydraulic devices.The QT pumps are also highly acclaimed for their excellent energy-saving properties.
Furthermore, our highly reliable hydraulic control valves are used not only in high-precision hydraulic systems but also in general and special vehicles, as well as high-speed ships and jetfoils, also known as aircraft of the sea. Our products also include high-performance hydraulic control systems for steel production facilities.

Coolant Equipment

Coolant pumps supply the coolant liquid essential for machining. Our wide range of coolant pump series provides strong support for cutting processes, helping to produce high-precision products and shorten processing times. Sumitomo Precision 's "High-Pressure Coolant Pump Series" is characterized by its excellent low noise and space-saving design, and is also highly effective in improving the working environment at machining sites. In addition, inverter control is possible, greatly contributing to energy savings.
We also handle coolant units equipped with coolant pumps, filter systems, and control devices.
