An accessory kit with pressure reducing sandwich plate can be ordered from DYNATEC. ¹ Coupling for splined shaft according to ANSI B92.1a ² Other electrical connector might be diffenrent ³ Peference: SAE version from A-39 dynat

Technical data Notes on the choice of hydraulic fluid Hydraulic fluid In order to select the correct hydraulic fluid, it is necessary to know the operating temperature in the reservoir (open circuit) in relation to the ambient temperature. When using environmentally acceptable hydraulic fluids,the limitations regarding technical data and seals must be observed.Please contact us.When ordering,indicate the hydraulic fluid that is to be used. The hydraulic fluid should be selected so that within the operating temperature range, the viscosity lies within the optimum range(νopt), see shaded...

DG — Two-point control, directly operated The variable pump can be set to a minimum swivel angle by connecting an external control pressure to port X. This will supply control fluid directly to the stroke piston; a minimum control pressure of pst ≥ 725 psi (50 bar) is required.。 The variable pump can only be switched between Vg max or Vg min 。 Please note, that the required control pressure at port X is directly dependent on the actual operating pressure pB in port B. (See control pressure characteristic). Control pressure pst = 0 psi (0 bar) Control pressure pst ≥ 725 psi (50 bar) Control...

DR — Pressure control Circuit diagram,sizes 18 to 100 Hysteresis / pressure rise Static characteristic Setting rang¹ The pressure control limits the maximum pressure at the pump output within the pump control range. The variable pump only supplies as much hydraulic fluid as is required by the consumers.If the operating pressure exceeds the pressure setpoint set at the integrated pressure valve, the pump will adjust towards a smaller displacement and the control deviation will be reduced. The pressure can be set steplessly at the control valve. ¹ In order to prevent damage to the pump and...
