Stauff® 2.8L Diaphragm Accumulator 250 Bar – STDA-280-NBR-P4-B-M-N-1
The Stauff® STDA-280-NBR-P4-B-M-N-1 is a maximum-capacity 2.8L diaphragm accumulator engineered for high-volume energy storage and superior pressure stabilisation. Rated for a maximum working pressure of 250 bar, this genuine Stauff® unit provides critical dampening for hydraulic shocks and pulsations in heavy-duty industrial and mobile circuits.
Ideal for large-scale hydraulic applications, this Type STDA configuration features a robust NBR (Buna-N®) diaphragm and a tamper-proof, non-repairable construction for maximum safety. We offer Australia-wide shipping for this model. To ensure safe transit and comply with dangerous goods regulations, this unit is supplied with no gas pre-charge.
Product Benefits & Performance
- Maximum Energy Storage: The largest in the STDA series, providing significant pressure compensation and emergency power for high-demand systems.
- Industrial-Grade Stabilisation: Mitigates hydraulic "water hammer" and mechanical vibration in large-bore hydraulic lines.
- Maintenance-Free Safety: Sealed, non-repairable (STDA) design ensures long-term reliability without the need for internal servicing.
- Safe Nationwide Dispatch: Shipped uncharged to facilitate immediate delivery across Australia without dangerous goods restrictions.
