Product Overview
The SUNFAB SAP-056R-N-DL4-L35-S0S-000 is a high-performance axial piston pump engineered by Sunfab Hydraulics, a globally recognized manufacturer of premium hydraulic components for demanding mobile and industrial applications. This variable displacement axial piston pump utilizes a precision swashplate design, where the angle of the swashplate governs the stroke of the pistons within the rotating cylinder barrel, enabling infinitely variable flow output proportional to the control input. With a nominal displacement of 56 cm³/rev, this pump delivers exceptional volumetric efficiency and high-pressure capability, making it a critical power source in closed and open-loop hydraulic systems. The SAP series is specifically designed for robust continuous duty, offering superior performance in applications requiring precise flow control, high power density, and reliable operation under extreme operating conditions.
