Hydraulic and pneumatic equipment are used to control the distribution of fluids. They are also used in power generation applications where electrical motors are too costly, inefficient or unsafe.
Hydraulics rely on pumps to distribute liquid fluids for industrial processes and power generation, and pneumatic systems are powered by pressurized gases. Valves adjust the flow rate of fluids, and pipes carry the material through systems and facilities.
Both systems are widely used in construction, mining, chemical processing, and power generation applications.
