Hydraulic Tanks. Store fluids for a hydraulic power unit or circulating-oil system. Choose a tank capacity about three times greater than your requirement to allow for heat dissipation. Tanks with only a drain connection require you to drill your own inlet/outlet connection and add pipe suction flanges (sold separately).

Studies on a 20-ton hydraulic excavator show that the energy that can be potentially regenerated during one duty cycle from the boom, arm, bucket, and swing is as high as 260.4 kJ [3]. For a typical excavator truck-loading cycle, research shows that without energy regeneration the overall efficiency of the centralized system is as low as 22.5% [ 4 ].
