AXIAL PISTON PUMP A4VTG90
• Nominal pressure 400 bar
• Maximum pressure 450 bar
• Closed circuit
• For the drum drive in ready-mix concrete mixers
Features:
• Variable displacement pump in axial piston swash plate design for hydrostatic transmissions in a closed circuit
• The volume flow is proportional to the drive speed and the displacement volume and is infinitely variable
• As the swash plate swings out, the volume flow increases from 0 to its maximum value Jerk-free change in the flow direction of the volume flow when the swash plate is adjusted through the zero position
• Two pressure relief valves for the respective high-pressure side to protect the hydrostatic transmission (pump and motor) from overloading
• The high-pressure relief valves are also feed valves
• The integrated feed pump serves as a feed and control oil pump
• The maximum feed pressure is protected by the integrated feed pressure relief valve
