Nachi PVD-0B — variable displacement axial piston pump 24 cm³
Nachi PVD-0B is a split-flow variable displacement axial piston hydraulic pump of the PVD series. It generates two equal independent flows from two sections within a single housing, ensuring synchronous supply to the left and right travel motors and guaranteeing straight-line travel of the crawler undercarriage without operator correction. The next frame size in the series after PVD-00B, designed for mini excavators in the 2–2.5 tonne class. Variants within the frame size (PVD-0B-18, PVD-0B-19, PVD-0B-21, PVD-0B-24) differ in displacement while sharing the same rotary group and housing.
