Variable pump application
Variable pump is so called because its displacement volume can be changed. It generally has two types: the axial piston pump and the radial piston pump. This pump is widely applied in the hydraulic transmission system in many industries, such as metallurgy, mining, engineering machinery, shipbuilding, civil aviation ground equipment and more.
