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
