Accumulator

Arrow Hydraulic Accumulators – Engineered for Performance & Safety

Arrow provides high-performance hydraulic accumulators designed to optimize system efficiency, absorb shocks, and ensure reliable energy storage across critical industries. Our solutions leverage advanced bladder, piston, and diaphragm technologies to meet diverse operational demands.

Accumulator Types & Technology Comparison

1. Bladder Accumulators

Best For: Rapid energy release, shock absorption

Applications:

Construction equipment (e.g., excavator boom control)

Industrial presses (stamping, injection molding)

Mobile hydraulics (agricultural machinery)

Advantages:
✔ Fast response time
✔ High cycle life (500,000+ cycles)
✔ Compact design

Disadvantages:
✖ Limited fluid compatibility (avoid high-water-content fluids)
✖ Bladder replacement required periodically

2. Piston Accumulators

Best For: High-pressure, large-volume storage

Applications:

Offshore oil & gas (BOP systems)

Heavy industrial machinery (steel mills, forging presses)

Energy storage (wind turbine pitch control)

Advantages:
✔ Handles high pressures (5000+ PSI)
✔ Compatible with all hydraulic fluids
✔ Long service life with minimal maintenance

Disadvantages:
✖ Slower response than bladder types
✖ Heavier and bulkier

3. Diaphragm Accumulators

Best For: Small to medium-volume applications

Applications:

Automotive suspensions

HVAC systems

Light industrial machinery

Advantages:
✔ Cost-effective for lower pressures
✔ Simple maintenance

Disadvantages:
✖ Limited volume capacity
✖ Not suitable for high-cycle applications
