A4VTG90HW32R-NLD10F001S-S

Features below:

1.Variable axial piston pump of swashplate design for hydrostatic closed circuit transmissions
2.Flow is proportional to drive speed and displacement and is infinitely variable
3.Output flow increases with the swivel angle of the swashplate from 0 to its maximum value
4.Flow direction changes smoothly when the swashplate is moved through the neutral position
5.A wide range of highly adaptable control devices is available for different control and regulating functions
6.The pump is equipped with two pressure-relief valves on the high pressure ports to protect the hydrostatic transmission (pump and motor) from overload
7.The high-pressure relief valves also function as boost valves
8.The integrated boost pump acts as a feed and control oil pump
9.The maximum boost pressure is limited by a built-in boost pressure relief valve
10.The integral pressure cut-off is standard
