PVK Series - Hydraulic Axial Piston Pumps
| Variable Displacement Piston Pump for Excavators & Construction Machinery

The PVK Series Hydraulic Pump is a high-performance Variable Displacement Piston Pump developed by YEOSHE Hydraulic Technology specifically for excavators and construction machinery.
The pump features a compact design, allowing installation in confined engine compartments, and is equipped with a Constant Power Control mechanism, enabling the hydraulic pump to automatically adjust output according to operating conditions. This ensures effective utilization of engine power while improving overall operating speed and productivity.

The PVK Series is particularly suitable for 4–5 ton class excavators, combining high efficiency, stability, and durability. It provides a reliable and cost-effective hydraulic solution for small to medium construction equipment.
Through the integration of variable displacement control, constant power control, and a high-efficiency structural design, the PVK Series enhances machine response and operational productivity while reducing unnecessary energy loss, making it suitable for both OEM equipment integration and the aftermarket replacement sector.
