Axial Piston Brueninghaus Hydromatik A10VG18 A10VG28 A10VG45 A10VG63 Rexroth A10VG pump, for the control by HD, MD, HW, DG, DA, and EP etc.  
the A10VG series Features below:
Variable axial piston pump of swashplate design for hydrostatic closed circuit transmission
Flow is proportional to drive speed and displacement and is infinitely variable
Output flow increases with the swivel angle of the swashplate from 0 to its maximum value
Flow direction changes smoothly when the swashplate is moved through the neutral position
A wide range of highly adaptable control devices is available for different control and regulating functions
The pump is equipped with two pressure relief valves on the
high pressure ports to protect the hydrostatic transmission (pump and motor) from overload
The pressure relief valves also function as boost valves
The integrated boost pump acts as a feed and control oil pump
The maximum boost pressure is limited by a built-in boost pressure relief valve.
