AR SERIES

The AR Series from Yuken is a line of variable displacement axial piston pumps designed for energy-efficient, low-noise operation in high-performance hydraulic systems. These pumps are known for their compact construction, precise control, and reliable performance across a range of industrial and mobile applications.

Product Description

The AR Series pumps operate on the swash plate axial piston principle, providing variable flow rates that respond to system demand. The built-in pressure compensator automatically adjusts output to maintain constant pressure, reducing energy loss and heat generation. The compact design allows for easy integration into systems where space is limited.
