Axial Piston Pumps (Open Loop)K7V series
The K7V series are variable displacement axial piston pumps of swash plate design, suitable for use in mobile applications such as Excavators, Cranes, etc.
With the Kawasaki's latest technologies for improving efficiency and lowering noise, they achieve the world's top-level pump efficiency and low noise which contribute to energy saving on applications and comfortable working environment.
A long life is obtained by adopting large capacity of bearing and thicker shaft which reduces the load on the edge of bearing rollers.
Features
- High Pump Efficiency
- Low Noise
- High Reliavility
- High Power Density

Applications
Excavator System
Most common hydraulic system for the hydraulic excavators is a system with the variable displacement pump in the open center control system. Electronically controlled positive displacement control system, which is one of the excavator system, can optimize each operating function to provide efficient, smooth and precise control performance.
