Hydraulic Units

Hydraulic aggregates from FGB are designed to supply power to servo-hydraulic systems of various kinds. These kinds of systems make high demands on the pressure oil with respect to cleanliness and constant operating pressures. The aggregates we develop in-house are used at permanent operating pressures up to 300 bar and deliver flow rates adapted to the consumption. The pressure oil supply has been specially trimmed to the particular requirements of servo-hydraulic applications. For instance, the operating pressure can be set either manually or electrically between 50 and 280 bar. The flow rate adapts to the needs of the respective consumer via an axial piston pump with pressure control. The oil temperature in the tank is kept almost constant by means of a controlled bypass cooling system. The filter system has a separate cooling circuit.

The hydraulic units are used in the following areas, among others:

  • Test bench building
  • General engineering
  • Press building

Technical data:

  • Automatic adjustment of the flow rate to the corresponding demand via a control pump
  • Separate filter / cooling circuit
  • Low oil temperature fluctuation in the tank due to regulated bypass cooling
  • Low noise level due to soundproofing measures
  • Standard sizes: 30, 60, 100, 180, 250, 500 litres per minute conveyed volume
  • Coupling of the aggregates possible
