Stauff® 2.0L Diaphragm Accumulator 250 Bar – STDA-200

The Stauff® STDA-200-NBR-P4-B-M-N-1 is a high-capacity 2.0L diaphragm accumulator engineered for robust energy storage and pressure stabilisation in large-scale hydraulic circuits. Rated for a maximum working pressure of 250 bar, this genuine Stauff® unit effectively dampens hydraulic shocks and pulsations to safeguard critical system components.

Designed for heavy-duty industrial and mobile hydraulic applications, this Type STDA configuration features a durable NBR (Buna-N®) diaphragm and a tamper-proof, non-repairable construction. We offer Australia-wide shipping for this model. To ensure safe transport and full compliance with dangerous goods regulations, this unit is supplied with no gas pre-charge.

Product Benefits & Performance

• High-Capacity Stabilisation: Provides significant pressure compensation and emergency power backup for high-flow systems.
• Mechanical Protection: Mitigates hydraulic "water hammer" effects to reduce mechanical stress, noise, and vibration.
• Maintenance-Free Reliability: The sealed, non-repairable (STDA) design ensures a durable, safety-first solution for demanding environments.
• Nationwide Dispatch: Shipped uncharged to facilitate fast delivery across Australia without dangerous goods restrictions.
