Nachi PVD-2B — variable displacement axial piston pump 50 cm³
Nachi PVD-2B 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 frame size is designed for mini excavators in the 3–5 tonne class. Variants within the frame size (PVD-2B-34, PVD-2B-36, PVD-2B-38, PVD-2B-40, PVD-2B-42, PVD-2B-50) differ in displacement while sharing the same rotary group and housing. Right-hand (P) and left-hand (L) shaft rotation variants are available.

PVD-2B model code structure
Example: PVD-2B-40P-16G5-5220A
- PVD — split-flow piston pump
- 2B — frame size (max. 45 cm³/rev)
- 26 / 31 / 32 / 34 / 36 / 38 / 40 / 42 / 44 / 50 — maximum total displacement, cm³/rev
- P — right-hand rotation; L — left-hand rotation
- 3DPS / 3DS / 3 — port or mounting variant
- G3 / G5 / G6A — seal type and gear pump configuration (6 / 8 / 9 / 11 / 12 / 16 / 18 = displacement of the larger gear section, cm³/rev; the same piston section displacement can be combined with different gear pumps)
- 4515H / 4787J / 4117F / 5220A — serial specification suffix
