Nachi PVD-3B — variable displacement axial piston pump 66 cm³
Nachi PVD-3B is the largest frame size of the split-flow PVD series manufactured by Nachi. The design features two independent sections in a single housing, each generating an equal flow — synchronous supply to the left and right travel motors prevents the machine from deviating from a straight course without operator intervention. Designed for excavators in the 7–12 tonne class. Within the frame size, variants PVD-3B-54P, PVD-3B-56P and PVD-3B-60 are available — with different displacements and shaft rotation directions (P — right-hand, L — left-hand) while sharing the same rotary group and housing.
