Axial Piston Pumps (Closed Loop)K8V series

The K8V series are variable displacement axial piston pumps for closed loop system.
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.
Delivery flow is controlled precisely in response to control signal by mechanical feedback of swash plate tilting position.

Features

  • World's top-level pump efficiency and low noise
  • Precise flow control by position feedback of swash plate tilting position.
  • High reliability and Long life for high pressure spec.
  • Charge pump, High/Low pressure relief valve, and Cut-off valve are standard option.
  • Electric proportional control, Hydraulic pilot displacement control and Manual control are available.
