• Variable axial piston pump which integrates boost pump, relief valve and filtration, for closed circuit. 
• Motor output speed can be infinitely changed from zero to maximum through manually controlling pump. 
• Flow direction changes smoothly when the swash plate is moved through the neutral position. 
• Adaptively variable displacement makes a stronger drive power and higher system efficiency. 
• Pressure relief valve is provided on each pressure port to protect hydrostatic transmission from overloading.
• High pressure relief valves with integrated boost function.
• Integrated boost pump has functions to replenish oil and cool down . 
• Compact, small dimensions, light weight and low noise.
