A4VSG Axial piston variable High pressure pump , Closed circuit pumps

Control device

Hydraulic control HM 1/2, volume dependent (see data sheet 92076)
The pump displacement can be steplessly adjusted in relation to the pilot oil volume in ports X1 und X2.
Application:
  2-point circuit
  Base device for servo or proportional controls

Control system EO1/2
The stepless control of the displacement flow is accomplished by means of a proportional valve and electrical feedback of the swivel angle. Thus, the control can be used as an electric displacement control.
Optional:
Control pressure range (EO1, EO2)
Short circuit valve (EO1K, EO2K)
