Hydraulic axial piston pump K3VR series

closed circuittwo-speedsuction

Overview
The K3VR series are closed-circuit axial piston pumps designed for variable-speed control systems. The built-in large-capacity suction valve simplifies closed-circuit configuration and contributes to reduced noise and improved energy efficiency in industrial machinery.

Features

• Designed specifically for variable-speed control
• Two-step displacement switching control
• Built-in large-capacity suction valve
• Low pulsation and low-noise operation
• Wide model lineup covering 22–200 cm3

Control Curve
Example control curves illustrating pump response and displacement switching are provided on the product page to aid selection and tuning.
