PSVD

Main advantages and scope of application of Kayaba PSVD series hydraulic pumps

Kayaba PSVD hydraulic pumps are variable displacement axial piston pumps designed for use in construction, road construction and special equipment. They combine high performance with compactness and are ideal for hydraulic systems in excavators, skid steer loaders and other equipment.

Key advantages of Kayaba PSVD hydraulic pumps:

1. Variable displacement
   • Allows precise dosing of fluid flow during load changes.
   • Increases the energy efficiency of equipment, reducing fuel consumption.
2. Double section (two circuits in one housing)
   • A PSVD often has two pumps in one housing, which provides power to multiple circuits (e.g., motion and operating elements).
   • Space optimization and reduction of the number of components.
3. High reliability and resource
   • Japanese quality workmanship and materials.
   • Resistant to wear, work stably in difficult conditions (dirt, moisture, temperature changes).
4. Compact design
   • Ideal for mini appliances where every centimeter of space is critical.
   • Facilitates installation and maintenance.
5. Stable operation at high pressure
   • They operate at pressures up to 300 bar and higher, maintaining smoothness and accuracy of feed.
6. Built-in regulators and valves
   • May include pressure limiters, compensation and check valves.
   • Ensure safe and controlled operation.
7. Compatibility with well-known brands
   • Widely used in Hitachi, Yanmar, Takeuchi, Kubota, Kobelco, Komatsu, etc.
   • Availability of spare parts and maintainability.
