Hydraulic accumulators store the energy of pressurized oil in the system to:
Meet sudden flow demands
Reduce pump load
Absorb hydraulic shocks and vibrations
Provide safety in emergency situations
Improve energy efficiency
Incorrectly selected or improperly installed accumulators can cause cavitation, excessive pressure fluctuations, and significant reduction in equipment lifespan.

| Support Brackets & Clamps | Quick and easy installation, carbon/stainless steel | Mounting and securing accumulators |
| Safety Blocks | Ensure safety during accumulator maintenance and operation | Standard and special applications |
| Parameter | Typical Range |
|---|---|
| Operating Pressure | 100 – 350 bar |
| Volume Capacity | 0.5 – 200 liters |
| Gas Pre-Charge | 30 – 150 bar |
| Material | Steel, stainless steel |
| Standards | ISO 4413, CE, PED |
Pressure & Volume: Must match system requirements
Gas Pre-Charge: Incorrect adjustment reduces performance
Type Selection: Piston, diaphragm, or bladder depending on application
Material: Steel or stainless steel depending on environment
Standards: ISO and CE compliance mandatory
Incorrect gas pre-charge → performance loss
Insufficient volume → pressure fluctuations
Inappropriate material → corrosion risk
Installation errors → internal leakage and early failure
Neglected maintenance → reduced system safety
