Baile Hydraulic A4VTG Hydraulic pump A4VTG071EP3 A4VTG071EP4 A4VTG071HW1 Rexroth Axial Piston Variable Pump

Series 33
Sizes NG71, 90
Nominal pressure 5800 psi (400 bar)
Maximum pressure 6500 psi (450 bar)
Closed circuit
For the drum drive in mobile concrete mixers

Features
– 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 transmission (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 maximum boost pressure is limited by a built-in boost
pressure-relief valve.
– Tapered shaft option for direct drive shaft yoke installation
