2.2 PVE Series (Fixed Displacement Axial Piston Pump)

This series is a fixed displacement axial piston pump with simple structure, low cost and reliable performance. It is suitable for light track maintenance machinery with fixed working conditions, such as manual rail lifting jacks and small track cleaning machines, and can provide stable hydraulic power for single working mechanism.
