Product Overview
The YUKEN A56-F-R-01-H-S-K-32 is a variable displacement axial piston pump from the renowned YUKEN A Series, engineered for high-pressure industrial hydraulic systems requiring precise flow control and energy-efficient operation. Utilizing an inclined swashplate working principle, this pump converts rotational mechanical input into hydraulic power through a set of axially arranged pistons reciprocating within a precision-machined cylinder barrel. The variable displacement mechanism allows the swashplate angle to be adjusted, enabling stepless control of output flow to match system demand, thereby reducing heat generation and power consumption. With a nominal displacement of 56 cm³/rev, this model is widely deployed as a central pressure source in demanding industrial circuits where reliability, response, and volumetric efficiency are critical.
