Where Accumulators Improve Equipment Performance

OEMs and integrators pair accumulators with Purpose-Built cylinders in applications that need smoother load control.

Common Accumulator Applications:

Shock reduction during actuator reversal.
Added stability in material handling and lifting systems.
Emergency actuation in case of loss of main pump flow.
Dampens pressure fluctuations in hydraulic systems.

Aggressive Hydraulics Piston Accumulator Components

Our piston accumulators use a sealed piston assembly that separates hydraulic fluid from nitrogen gas. The system pressure moves the piston and compresses the gas. As pressure falls, the gas expands and pushes the fluid back into the circuit.

Accumulator Sizing Considerations

Correct sizing depends on accurate calculations.

Minimum and maximum pressure.
Required usable volume.
Space considerations.
Load mass and operating speed.
Required response time and duty cycle.

Integration Best Practices

You get the best results from an accumulator when the following criteria are met.

Mount the accumulator close to the actuator circuit.
Use isolation valves for servicing.
Charge with nitrogen using proper equipment and procedures.
Use clean, compatible hydraulic fluid.
Maintain the accumulator pre-charge as part of your service plan.
