Product Overview

The NACHI PVD-1B-32P-11G5-5677A 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 precisely angled swashplate acting against a rotating cylinder barrel containing multiple axial pistons. As a variable displacement unit, it delivers on-demand flow by modulating the swashplate angle, enabling energy-efficient operation, reduced heat generation, and precise actuator speed control in demanding industrial hydraulic systems. The PVD-1B series is widely specified for applications requiring high pressure, quiet operation, and reliable continuous duty performance.
