NACHI PVD-00B-14/15/16 Hydraulic Pump
1. Product Overview
The NACHI PVD-00B series pumps are compact variable displacement axial piston pumps manufactured by NACHI-FUJIKOSHI. Models PVD-00B-14, PVD-00B-15, PVD-00B-16 are widely fitted on mini excavators ranging from 1 ton to 3.5 tons. This series is the main hydraulic power source for small construction machinery, characterized by small size, lightweight structure, low noise and reliable performance. It supports multiple control modes and is a mainstream original main pump for micro excavators.
