A Genuine Cross-Brand Platform for Mini & Compact Excavators
Mini and compact excavators from Hitachi (ZX30U-class), Komatsu (PC40-class), and several other brands genuinely converge on the same Nachi PVD combination pump platform — a piston pump and gear pump built into one housing, running all the machine's hydraulic functions. The body brand won't tell you the exact pump variant; that comes from the pump's own nameplate.
Nachi's dominance in the mini/compact excavator segment reflects genuine engineering specialization — the PVD series was purpose-built to fit the tight packaging and cost constraints of small excavators, combining what would otherwise be two separate pumps into one unit. This is exactly why the pump shows up across so many different excavator brands rather than each manufacturer building its own compact-class solution.
| Machine Class | Common Nachi Part | Brands Documented |
|---|---|---|
| Mini (~1-2 tonne) | PVD-1B-32P | Multiple mini excavator brands |
| Compact (~3-4 tonne) | PVD-2B-36L / PVD-2B-40P | Hitachi ZX30U-class, Komatsu PC40-class |
| Compact (~4-5 tonne) | PVD-2B-45P / PVD-2B-50P | Multiple compact excavator brands |
