PSVK2 series

Main advantages and scope of application of Kayaba PSVK2 Series hydraulic pumps

Kayaba PSVK2 series hydraulic pumps are two-section axial piston pumps with variable displacement, designed for modern construction equipment, particularly medium and large excavators. They combine high power, reliability and precise hydraulic flow control, making them an effective solution for difficult operating conditions.

Key advantages of Kayaba PSVK2 Series hydraulic pumps:

1. Two-section design (Twin Pump System)
   • Two independent pumps in one housing supply power to multiple hydraulic circuits (e.g. boom + travel).
   • Increased compactness and reduced number of individual components.
2. Variable displacement
   • Automatic adjustment of oil flow depending on load.
   • Provides energy-efficient operation and reduces fuel consumption.
3. High power and pressure
   • They operate at pressures up to 350 bar, which allows them to work with heavy loads.
   • They provide high speed and accuracy of movement of working bodies.
4. Integrated control systems
   • Equipped with electro-hydraulic flow and pressure regulators.
   • Support for intelligent flow control for modern technology.
5. Reliability in harsh conditions
   • High-precision Japanese processing and durable materials.
   • Protection against overload, water hammer and overheating.
6. Minimum noise and vibration levels
   • Specially designed to reduce noise pollution.
   • Smooth and quiet operation even under heavy load.
7. Compatibility with leading equipment manufacturers
   • Used in Komatsu, Hitachi, Doosan, Hyundai, Volvo and other machines.
   • Well-established as OEM solutions and as replacements in repairs.
