Product Overview

The NACHI PVD-1B-34P-3AG6-5314D is a variable displacement axial piston pump engineered by NACHI-FUJIKOSHI CORP., a globally recognized leader in precision hydraulic technology. Operating on the proven swashplate principle, this pump converts mechanical input power into high-pressure hydraulic flow through a precision-machined cylinder block and axial piston assembly. The variable displacement mechanism allows the swashplate angle to be modulated, enabling precise control of output flow to match system demand. This results in significant energy savings, reduced heat generation, and optimized cycle times in demanding industrial hydraulic circuits. The PVD series is specifically designed for open-loop systems requiring high pressure capability, compact installation envelopes, and reliable continuous-duty performance.
