A4VTG Series Axial piston variable pump

— Variable axial piston pump of swashplate design for hydrostatic drives in closed circuit
— The flow is proportional to the drive speed and displacement.
— The flow increases as the angle of the swashplate is adjusted from zero to its maximum value.
— Flow direction changes smoothly when the swashplate is moved through the neutral position.
— Two pressure-relief valves are provided on the high pressure ports to protect the hydrostatic tansmission(pump and motor) from overload.
— The high-pressure relief valves also function as boost valves.
— The integrated boost pump acts as a feed pump and control pressure supply.
— The maximun boost pressure is limited by a built-in boost pressure-relief valve.
— Tapered shaft option for direct drive shaft yoke installation.
