Product Overview
The NACHI PVD-0B-18P-6G3-4191A 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-ground cylinder block and axial piston assembly, with displacement infinitely adjustable via an integrated compensator control. The PVD series is purpose-built for compact, high-efficiency hydraulic power units where stable pressure delivery, low pulsation, and precise flow control are essential. With its 18 cm³/rev nominal displacement and robust construction, the PVD-0B-18P-6G3-4191A serves as a direct-fit replacement for OEM installations in demanding industrial and mobile hydraulic systems.
