Key features and applications of Kawasaki K5V series hydraulic pumps
The Kawasaki K5V series hydraulic pumps are a new generation of variable displacient axial piston pumps, developed based on Kawasaki's many years of hydraulics expertise. They are primarily designed for mobile construction equipment, including modern medium and heavy excavators.
Here are the main advantages of Kawasaki K5V series pumps:
- Improved new generation design
- The K5V series is the successor to the popular K3V series, with improved reliability, performance, and efficiency.
- Designed taking into account modern requirients for economy, environmental friendliness and digital integration.
- High power density
- High working pressure (up to 350 bar) with compact dimensions.
- Allows you to place more power in a smaller volume of the hydraulic systi, which is important for modern technology.
- Twin pump design
- K5V models typically have two pump sections in one housing, allowing multiple functions to be controlled simultaneously (travel, boom, swing).
- Ideal for complex excavator hydraulic systis.
- High-precision electro-hydraulic control
- Support for modern controllers: Load Sensing (LS), electro-hydraulic controllers, EPC (Electronic Proportional Control).
- Allows you to precisely adapt flow rates to the load, reducing fuel consumption.
- Noise and vibration reduction
- Improved cylinder block geometry and flow channels help reduce noise and vibration—important for operator comfort.
- Reliability and long service life
- Wear-resistant materials, an optimized lubrication systi, and protection against internal leaks are used.
- Designed for long-term operation in difficult conditions (construction, mining).
- Energy efficiency and compliance with environmental standards
- Thanks to optimized energy consumption, the pump helps reduce the fuel consumption of the equipment.
- Meets modern environmental requirients (Tier IV/Stage V).
- Uniformity and easy maintenance
- Compatibility with systis and components of other Kawasaki models (e.g. K3V).
- Convenience in diagnostics, availability of spare parts, modular design.
Ideal applications for Kawasaki series K5V pumps:
- Crawler excavators (20–40+ tons)
- Quarrying and mining equipment
- Specialized machines with high load
