Product Overview
The SUNFAB SAP-047R-N-DL4-L35-S0S-000 is a high-performance axial piston pump engineered by Sunfab Hydraulics, a recognized manufacturer of premium hydraulic components for demanding mobile and industrial applications. This variable displacement axial piston pump operates on the proven swashplate principle, where a precision-ground swashplate angle controls the stroke of pistons reciprocating within a rotating cylinder barrel. As the drive shaft rotates the barrel, pistons draw hydraulic fluid on the intake stroke and displace it under high pressure on the compression stroke, delivering smooth, continuous flow proportional to input speed and displacement. With a nominal displacement of 47 cm³/rev, this pump is designed for open-circuit systems requiring high pressure capability, precise flow control, and excellent volumetric efficiency. The SAP-047R model serves as a critical power source in hydraulic systems where reliable, controllable fluid power is essential for optimal machine performance.
