      Series advantages

      • Swash plate design axial piston variable pump for closed-loop hydrostatic transmission

      • As the swash plate passes through the center, the direction of the hydraulic oil flow changes smoothly

      • Two pressure relief valves are installed on the high-pressure side to prevent overloading

      • The built-in make-up pump acts as a make-up pump and control pump

      • The maximum make-up pressure is limited by the built-in low-pressure relief valve

      • New slewing components and bearings for improved transmission efficiency and higher input speed

      • The V40G pump features a one-piece housing and back cover design to reduce leakage points

      • Optimized housing design for vibration and noise reduction

      • Electrical proportional displacement control to meet the requirements of multi-industry applications

      • A variety of oil outlet connection methods to optimize the pipeline connection

      • An optional flushing valve can be installed directly on the pump body
