NACHI PVD-2B-40P-6G3-4515H PVD Series Excavator Piston Pump

NACHI PVD Series Piston Pump

The NACHI PVD is a variable displacement axial piston pump developed for compact excavator hydraulic systems.

Unlike a simple single-output pump, the PVD is designed to provide two equal flow outputs from one pump assembly. This configuration is particularly useful for excavator hydraulic systems because balanced flow can help maintain straight-line travel performance.

The PVD series also uses constant horsepower control. The control system is designed to make effective use of the available engine power while preventing the hydraulic pump from demanding excessive power.

Another important characteristic is its compact size. NACHI specifically describes the PVD as suitable for installation in limited engine-room space.

Key features of the NACHI PVD series include:
Variable displacement axial piston design
Two equal flow outputs from one pump
Constant horsepower control
Compact overall construction
Suitable for mini and compact excavators
