Characteristics of the Nachi PVD-2B-32/34/36/40 hydraulic pump
Nachi PVD-2B-32/34/36/40 hydraulic pumps are tandem (twin) axial piston pumps with variable displacement, designed for heavy-duty applications in special equipment. Their key advantages are high performance, energy efficiency and the ability to deliver two equal flows from one housing, which is ideal for running the chassis and working equipment simultaneously. Their compact design and low noise level make them the optimal choice for modern excavators.
