Hydraulic Accumulators
Improving Your Manufacturing Efficiency


Hydraulic Accumulators


Rexroth hydraulic accumulators save energy and improve manufacturing efficiency by using the accumulator as a storage device to store hydraulic pump output flow when system demand is low and supplement output when demand is high.

Our hydraulic accumulators are used to:
  • Store power for intermittent duty cycles, economizing hydraulic pump drive power
  • Provide emergency or standby power
  • Compensate for leakage loss
  • Provide suspension in vehicles
  • Dampen pulsations and shocks of a periodic nature
