K8V Series Pump

Variable Displacement Swash Plate Design, Closed Loop.

The K8V series with a range in pump size from 71 to 130 cm3/rev are equipped with electric or hydraulic pilot displacement control. The K8V series pumps, having the integrated components required for a closed system, such as a charge pump, high and low-pressure relief valves, and a cut-off valve, enable a compact closed loop system.

The K8V series are variable displacement axial piston pumps for closed loop system. With the 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.
  • A charge pump, High/ Low-pressure relief valve, and Cut-off valve are a standard option
  • Electric proportional control, Hydraulic pilot displacement control, and Manual control are available.
