A SERIES

The A Series from Yuken Hydraulics consists of variable displacement swash plate axial piston pumps designed for high efficiency, stable pressure control, and compact form factors. Known for their quiet operation and long service life, these pumps are widely used in a variety of industrial hydraulic systems where reliable pressure and flow control are critical.

Product Description

The Yuken A Series pumps utilize a swash plate axial piston mechanism with variable displacement control, allowing the pump to adjust output flow according to the hydraulic system's demands. This reduces energy consumption, heat generation, and mechanical stress on system components. The pumps are equipped with pressure compensators and can be adapted with various control options, including remote pressure control and load sensing.
